107 ideas

1. Philosophy / E. Nature of Metaphysics / 5. Metaphysics beyond Science
Metaphysics goes beyond the empirical, so doesn't need examples [Kant]
     Full Idea: Metaphysics doesn't let itself be held back by anything empirical, and indeed goes right to Ideas, where examples themselves fail.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 412.36)
2. Reason / A. Nature of Reason / 4. Aims of Reason
The hallmark of rationality is setting itself an end [Kant]
     Full Idea: Rational nature separates itself out from all other things by the fact that it sets itself an end.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 437.82)
2. Reason / F. Fallacies / 2. Infinite Regress
Vicious regresses force you to another level; non-vicious imply another level [Baron/Miller]
     Full Idea: A regress is vicious if the problem at level n can only be solved at level n+1; it is non-vicious if it can be solved at n, but the solution forces another level n+1, where the problem can be reformulated.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 2.3.2)
     A reaction: So in a vicious regress you chase the apparent solution, but never attain it. In the non-vicious you solve it, but then find you have a new problem. I think.
5. Theory of Logic / L. Paradox / 7. Paradoxes of Time
A traveller takes a copy of a picture into the past, gives it the artist, who then creates the original! [Baron/Miller]
     Full Idea: Suppose an art critic travels back in time with a copy of an artist's masterpiece, gives the artist the copy, and the artist copies it. The copy of the copy turns out to be the original mastepiece. The artwork seems to come from nowhere.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 8.6)
     A reaction: Lovely thought. Is the example possible (even with time travel)? How would the critic possess the copy before making the time journey? What if the critic decided not to travel back in time? Can a picture exist if no one has imagined it first?
7. Existence / C. Structure of Existence / 1. Grounding / a. Nature of grounding
Grounding is intended as a relation that fits dependences between things [Baron/Miller]
     Full Idea: Grounding is a posit introduced by metaphysicians in an attempt to devise a relation that can accommodate dependence between things in the world.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 5.6)
     A reaction: Grounding is a recent concept which seems to have lots of enemies, but I assume you can only reject it if you reject the concept of dependence - yet that seems a fairly obvious fact to me. My favoured metaphysical relation is 'determination'.
9. Objects / E. Objects over Time / 2. Objects that Change
How does a changing object retain identity or have incompatible properties over time? [Baron/Miller]
     Full Idea: The problems of temporary intrinsics are reconciling the indiscernibility of identicals with change in an object over time, and the problem of something have incompatible properties over time (such as tired and not-tired).
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 7.3.1)
     A reaction: Loosely speaking, I would offer some sort of essentialism as the answer to these problems. People are not essentially sitting down, or tired. Or we can relativise properties to times t1 and t2.
12. Knowledge Sources / A. A Priori Knowledge / 5. A Priori Synthetic
The categorical imperative is a practical synthetic a priori proposition [Kant]
     Full Idea: With the categorical imperative or law of morality we have a very serious difficulty, because it is a synthetic a priori practical proposition.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 420.50)
15. Nature of Minds / B. Features of Minds / 5. Qualia / b. Qualia and intentionality
Qualities of experience are just representational aspects of experience ('Representationalism') [Harman, by Burge]
     Full Idea: Harman defended what came to be known as 'representationalism' - the view that qualitative aspects of experience are nothing other than representational aspects.
     From: report of Gilbert Harman (The Intrinsic Quality of Experience [1990]) by Tyler Burge - Philosophy of Mind: 1950-2000 p.459
     A reaction: Functionalists like Harman have a fairly intractable problem with the qualities of experience, and this may be clutching at straws. What does 'represent' mean? How is the representation achieved? Why that particular quale?
16. Persons / F. Free Will / 1. Nature of Free Will
Free will is a kind of causality which works independently of other causes [Kant]
     Full Idea: Will is a kind of causality belonging to living beings so far as they are rational. Freedom would then be the property this causality has of being able to work independently of determination by alien causes.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 446.97)
16. Persons / F. Free Will / 2. Sources of Free Will
We shall never be able to comprehend how freedom is possible [Kant]
     Full Idea: We shall never be able to comprehend how freedom is possible.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 456.115)
16. Persons / F. Free Will / 4. For Free Will
We cannot conceive of reason as being externally controlled [Kant]
     Full Idea: We cannot possibly conceive of a reason as being consciously directed from outside in regard to its judgements.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 448.101)
16. Persons / F. Free Will / 5. Against Free Will
Kant made the political will into a pure self-determined "free" will [Kant, by Marx/Engels]
     Full Idea: Kant made the materially motivated determinations of the will of the French bourgeois into pure self-determinations of the "free will", of the will in and for itself.
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by K Marx / F Engels - The German Ideology §II
     A reaction: This is the social determinism of Marx and Engels. Most commentators would say that Kant was taking the idea of "free will" from religion rather than politics, but presumably Marx would merely reply "same thing!"
18. Thought / A. Modes of Thought / 3. Emotions / c. Role of emotions
Kant thought emotions are too random and passive to be part of morality [Kant, by Williams,B]
     Full Idea: Kant thinks emotions can't contribute to moral worth because emotions are too capricious, they are too passive, and they are fortuitously distributed by nature.
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Bernard Williams - Morality and the emotions p.226
     A reaction: [compressed] If, like Kant, you want morality to be concerned with rational principles, then you will want morality to be clear, stable and consistent - which emotions are not. I'm with Williams on this one.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / b. Rational ethics
Kant united religion and philosophy, by basing obedience to law on reason instead of faith [Taylor,R on Kant]
     Full Idea: Kant united the two ideas of virtue (as being and as doing) into the idea of a law that is founded not upon faith but upon reason. Thus in one stroke he united the seemingly irreconcilable philosophical and religious ethics, preserving the best of both.
     From: comment on Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Richard Taylor - Virtue Ethics: an Introduction Ch.8
     A reaction: An interesting analysis that sounds exactly right. Taylor's point is that Kant subjects himself to an authority, when the underpinnings of the authority are no longer there. There is a religious strand in the altruistic requirements of utilitarianism too.
The categorical imperative says nothing about what our activities and ends should be [MacIntyre on Kant]
     Full Idea: As to what activities we ought to engage in, what ends we should pursue, the categorical imperative seems to be silent.
     From: comment on Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Alasdair MacIntyre - A Short History of Ethics Ch.14
     A reaction: I think this is the fatal objection to Kant's view. He says, for example, that promise-breaking is inconsistent with a belief that promises are good, but who said promises are good? No ethical system can get started without values.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / e. Human nature
Kant thought human nature was pure hedonism, so virtue is only possible via the categorical imperative [Foot on Kant]
     Full Idea: Kant was a psychological hedonist about all actions except those done for the sake of the moral law, and this faulty theory of human nature prevented him from seeing that moral virtue might be compatible with the rejection of the categorical imperative.
     From: comment on Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Philippa Foot - Morality as system of hypothetical imperatives p.165
     A reaction: Nice. Kant wasn't unusual in his view, which seems standard in the Renaissance and Enlightenment. Aristotle understood that it is human nature, on the whole, to want to be a good citizen, since we are social beings.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / j. Ethics by convention
We must only value what others find acceptable [Kant, by Korsgaard]
     Full Idea: We are limited to pursuits which are acceptable from the standpoint of others; ..hence we can't value just anything, and there are things which we must value.
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Christine M. Korsgaard - Intro to 'Creating the Kingdom of Ends' x
     A reaction: This at least moves towards greater objectivity, compared with Idea 9749, but it now seems deeply conservative. Our values become lowest common denominator. We need space for the Nietzschean moral hero, who creates new values.
22. Metaethics / B. Value / 1. Nature of Value / a. Nature of value
Kant focuses exclusively on human values, and neglects cultural and personal values [Kekes on Kant]
     Full Idea: Kant grossly inflated the importance of the human dimension of value in which moral considerations are indeed overriding. He unjustifiably denied the perfectly reasonable contributions of the cultural and personal dimensions to human well-being.
     From: comment on Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by John Kekes - The Human Condition 05.5
     A reaction: Excellent to see someone talking about the ultimate values that reside behind Kant's theory. Without such assumptions his theory is, frankly, ridiculous (as Mill explained).
22. Metaethics / B. Value / 1. Nature of Value / d. Subjective value
Our rational choices confer value, arising from the sense that we ourselves are important [Kant, by Korsgaard]
     Full Idea: According to Kant, we confer value on the objects of our rational choices. ..When we choose things because they are important to us we are taking ourselves to be important. Hence our humanity is a source of value.
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Christine M. Korsgaard - Intro to 'Creating the Kingdom of Ends' ix
     A reaction: He's trying to filter to out our gormless choices with the word 'rational', but it is common sense that I may choose things despite thinking they have little value, like watching soap opera. A more objective account of value seems needed. See 9750!
Values are created by human choices, and are not some intrinsic quality, out there [Kant, by Berlin]
     Full Idea: Kant's fundamental sermon is that a value is made a value (or, at least, a duty) by human choice and not by some intrinsic quality in itself, out there. Values are what humans freely choose to live, fight and die for.
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Isaiah Berlin - The Roots of Romanticism Ch.4
     A reaction: If this is right, then it would appear that the great Kant is the father of relativism, which wouldn't please him. However, his whole system rests on what is consistent and rational, and that seems to a value that is above our choices.
22. Metaethics / B. Value / 2. Values / f. Altruism
Reverence is awareness of a value which demolishes my self-love [Kant]
     Full Idea: Reverence is awareness of a value which demolishes my self-love.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 401.16 n)
     A reaction: Presumably simple love of someone or something could achieve this, without the addition of reverence. I'm suspicious of this idea, because some dreadful people have commanded reverence.
We may claim noble motives, but we cannot penetrate our secret impulses [Kant]
     Full Idea: We are pleased to flatter ourselves with the false claim to a nobler motive, but in fact we can never, even by the most strenuous self-examination, get to the bottom of our secret impulsions.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 407.26)
     A reaction: Sounds more like Nietzsche than Kant. If some impulsions are totally hidden from us, then they are presumably irrelevant to any rational or moral thinking. Look at the deeds.
22. Metaethics / C. The Good / 1. Goodness / g. Consequentialism
A good will is not good because of what it achieves [Kant]
     Full Idea: A good will is not good because of what it effects or accomplishes.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 394.3)
     A reaction: This invites the obvious objection of the well-meaning fool, who causes misery despite meaning well. I firmly hold the view that what matters is what we do, not what we intend.
The good of an action is in the mind of the doer, not the consequences [Kant]
     Full Idea: What is essentially good in an action consists in the mental disposition, let the consequences be what they may.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 416.43)
     A reaction: Dreadful idea. I always claim that consequences are relevant in Kant, in formulating and choosing maxims for action, but this idea seems to refute my view. This is a slogan for the Spanish Inquisition.
23. Ethics / B. Contract Ethics / 2. Golden Rule
The 'golden rule' cannot be a universal law as it implies no duties [Kant]
     Full Idea: The 'golden rule' is merely derivative from our principle, but it cannot be a universal law since it isn't the ground of duties to oneself or others (since it implies a breakable contract).
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 430.68 n)
23. Ethics / C. Virtue Theory / 1. Virtue Theory / a. Nature of virtue
Virtue lets a rational being make universal law, and share in the kingdom of ends [Kant]
     Full Idea: A morally good attitude of mind (or virtue) claims the intrinsic value of dignity, because it affords a rational being a share in the making of universal law, which therefore fits him to be a member in a possible kingdom of ends.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 435.79)
23. Ethics / C. Virtue Theory / 1. Virtue Theory / d. Virtue theory critique
Kant thinks virtue becomes passive, and hence morally unaccountable [Kant, by Annas]
     Full Idea: Kant thinks that if virtue becomes a stable disposition of the person, then it turns into a rigid mechanical habit, with respect to which the person is passive, and thus not fully morally accountable.
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Julia Annas - The Morality of Happiness 2.1
23. Ethics / C. Virtue Theory / 3. Virtues / f. Compassion
Generosity and pity are vices, because they falsely imply one person's superiority to another [Kant, by Berlin]
     Full Idea: For Kant, generosity is a vice, because it is a form of condescension and patronage, and pity is detestable, because it entails a superiority on the part of the pitier, which Kant stoutly denied.
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Isaiah Berlin - The Roots of Romanticism
     A reaction: An interesting view, but being too proud to receive help from friends strikes me as a greater vice. How can friendship and community be built, if we do not rush to help one another when needed? The virtue is generosity without condescension.
23. Ethics / C. Virtue Theory / 3. Virtues / h. Respect
Kantian respect is for humanity and reason (not from love or sympathy or solidarity) [Kant, by Sandel]
     Full Idea: Kantian respect is unlike love. It's unlike sympathy. It's unlike solidarity or fellow feeling. ...Kantian respect is for humanity as such, for a rational capacity that resides, undifferentiated, in all of us.
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Michael J. Sandel - Justice: What's the right thing to do? 05
     A reaction: Why is it 'undifferentiated'? If reason is the source of the respect, why don't greater powers of reason command greater respect? The nice thing is that the rejected versions involve bias, but Kant's version does not.
23. Ethics / D. Deontological Ethics / 1. Deontology
If 'maxims' are deeper underlying intentions, Kant can be read as a virtue theorist [Kant, by Statman]
     Full Idea: It has been argued that by 'maxim' Kant does not mean a specific intention for some discrete act, but the underlying intention by which the agent orchestrates his numerous more specific intentions, ...which leads to a virtue reading of Kant.
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Daniel Statman - Introduction to Virtue Ethics §7
     A reaction: Kant admired virtue of character, and would want to fit it into the framework of his moral duties. Nevertheless a virtue would often seem to be beyond words, and principles seem to crumble in the face of complex cases.
We can ask how rational goodness is, but also why is rationality good [Putnam on Kant]
     Full Idea: We can reverse the terms of the comparison and ask not how rational is goodness, but why is it good to be rational?
     From: comment on Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Hilary Putnam - Reason, Truth and History
     A reaction: [Putnam doesn't mention Kant]. This seems to me to be the biggest question for Kant. See Idea 1403. The main point of tbe romantic movement, I take it, is that purely rational living does not bring happiness or fulfilment.
Kant follows Rousseau in defining freedom and morality in terms of each other [Taylor,C on Kant]
     Full Idea: Kant follows Rousseau in defining freedom and morality essentially in terms of each other.
     From: comment on Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Charles Taylor - Sources of the Self §20.2
     A reaction: An interesting comment on the modern tendency to overvalue freedom at the expense of the other civic virtues.
The only purely good thing is a good will [Kant]
     Full Idea: It is impossible to conceive anything at all in the world, or even out of it, which can be taken as good without qualification, except a good will.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 393.1)
     A reaction: This is precisely the thought of Epictetus, that the will is the source of goodness, because morality resides in choices (as opposed to character, or states of affairs).
The will is good if its universalised maxim is never in conflict with itself [Kant]
     Full Idea: The will is absolutely good if it cannot be evil - that is, if its maxim, when made into a universal law, can never be in conflict with itself.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 437.81)
Other causes can produce nice results, so morality must consist in the law, found only in rational beings [Kant]
     Full Idea: Agreeable results could be brought about by other causes;…therefore nothing but the idea of the law in itself, which is present only in a rational being, can constitute that pre-eminent good which we call moral.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 401.15)
It is basic that moral actions must be done from duty [Kant]
     Full Idea: The first proposition of morality is that to have moral worth an action must be done from duty.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], p.19), quoted by Brian Davies - Introduction to the Philosophy of Religion 9 'Religion'
     A reaction: [p.19 in Beck tr] In Aristotle's account these are 'controlled' actions [enkrateia], which are a step below virtuous actions, which combine reason and pleasure.
23. Ethics / D. Deontological Ethics / 2. Duty
Telling the truth from duty is quite different from doing so to avoid inconvenience [Kant]
     Full Idea: To tell the truth for the sake of duty is something entirely different from doing so out of concern for inconvenient results.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 402.18)
Men are subject to laws which are both self-made and universal [Kant]
     Full Idea: Man is subject only to laws which are made by himself and yet are universal.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 432.73)
Dutiful actions are judged not by purpose, but by the maxim followed [Kant]
     Full Idea: An action done from duty has its moral worth, not in the purpose to be attained by it, but in the maxim according to which it is decided upon.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 399.13)
Kant was happy with 'good will', even if it had no result [Kant, by Marx/Engels]
     Full Idea: Kant was satisfied with "good will" alone, even if it remained entirely without result.
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by K Marx / F Engels - The German Ideology §II
     A reaction: Kant is obviously a million miles away from Marxist pragmatism. And yet the members of the revolutionary class can only be identified and endorsed if they show a particular kind of will.
A categorical imperative sees an action as necessary purely for its own sake [Kant]
     Full Idea: A categorical imperative would be one which represented an action as objectively necessary in itself apart from its relation to a further end.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 414.39)
There are no imperatives for a holy will, as the will is in harmony with moral law [Kant]
     Full Idea: For the divine or holy will there are no imperatives: 'I ought' is here out of place, because 'I will' is already of itself necessarily in harmony with the law.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 414.39)
Kant has to attribute high moral worth to some deeply unattractive human lives [Kant, by Graham]
     Full Idea: An implausible and uncomfortable conclusion to be drawn from Kant's conception of morality is that we must attribute high moral worth to deeply unattractive human lives.
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Gordon Graham - Eight Theories of Ethics Ch.6
     A reaction: Graham quotes a loathsome character from a Victorian novel, who coldly 'does her duty'. Indeed it might be that a robot could be programmed with the categorical imperative (though it would need a table of values first). Virtue theory is the answer.
Kantian duty seems to imply conformism with authority [MacIntyre on Kant]
     Full Idea: Anyone educated into the Kantian notion of duty will (so far) have been educated into easy conformism with authority.
     From: comment on Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Alasdair MacIntyre - A Short History of Ethics Ch.14
     A reaction: The Nazi Eichmann cited Kant at his trial for mass murder. I'm not sure the criticism is fair. There are surely times when the categorical imperative will go quite contrary to what the irrational authorities are implementing?
23. Ethics / D. Deontological Ethics / 3. Universalisability
Almost any precept can be consistently universalized [MacIntyre on Kant]
     Full Idea: With sufficient ingenuity, almost every precept can be consistently universalized.
     From: comment on Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Alasdair MacIntyre - A Short History of Ethics Ch.14
     A reaction: A concise statement of J.S.Mill's point (Idea 3762). The point is that Kant seems to allow burglary, as long as you don't complain when you are burgled. What sort of maxim would a suicidal mass murderer being willing to universalize?
23. Ethics / D. Deontological Ethics / 4. Categorical Imperative
Act as if your maxim were to become a universal law of nature [Kant]
     Full Idea: The universal imperative may also run as follows: 'Act as if the maxim of your action were to become through your will a universal law of nature'.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 421.52)
If lying were the universal law it would make promises impossible [Kant]
     Full Idea: I can indeed will to lie, but I can by no means will a universal law of lying; for by such a law there could properly be no promises at all.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 403.19)
Act according to a maxim you can will as a universal law [Kant]
     Full Idea: I ought never to act except in such a way that I can also will that my maxim should become a universal law.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 402.17)
The categorical imperative smells of cruelty [Nietzsche on Kant]
     Full Idea: The categorical imperative smells of cruelty.
     From: comment on Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Friedrich Nietzsche - On the Genealogy of Morals II.§6
     A reaction: I presume this is because it is so pure and impersonal. Seems harsh. Nowadays we don't think pure just has to be cruel, but Nietzsche may have assumed it had to be.
The intuition behind the categorical imperative is that one ought not to make an exception of oneself [Kant, by Finlayson]
     Full Idea: Kant's first formulation of the categorical imperative is supposed to capture the widespread intuition that one ought not to make an exception of oneself.
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by James Gordon Finlayson - Habermas Ch.6:83
     A reaction: Interesting. I always take the plain English version to be 'what if everybody did that?' Suppose I were to forgive everyone, except myself?
Universalising a maxim needs to first stipulate the right description for the action [Anscombe on Kant]
     Full Idea: Kant's rule about universalisable maxims is useless without stipulations as to what shall count as a relevant description of an action with a view to constructing a maxim about it.
     From: comment on Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by G.E.M. Anscombe - Modern Moral Philosophy p.176
     A reaction: This is one of the key objections to Kant (along with his need for preliminary values). One man's 'terrorist' is another man's 'freedom fighter'. The charge adds up to Nietzsche's view, that Kant could never shake off his very conventional prejudices.
The categorical imperative will not suggest maxims suitable for testing [MacIntyre on Kant]
     Full Idea: The doctrine of the categorical imperative provides me with a test for rejecting proposed maxims; it does not tell me whence I am to derive the maxims which first provide the need for a test.
     From: comment on Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Alasdair MacIntyre - A Short History of Ethics Ch.14
     A reaction: Nice objection. 'What if we all stood on one leg for an hour (in this crisis)?' Question for Kant: what sort of maxims should we consider, when faced with a dilemma. Mill will obviously suggest happiness as a target. Good of society? My own good?
Why couldn't all rational beings accept outrageously immoral rules of conduct? [Mill on Kant]
     Full Idea: Kant fails, almost grotesquely, to show that there would be any logical or physical impossibility in the adoption by all rational beings of the most outrageously immoral rules of conduct.
     From: comment on Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by John Stuart Mill - Utilitarianism Ch.1
I can universalize a selfish maxim, if it is expressed in a way that only applies to me [MacIntyre on Kant]
     Full Idea: If we enquire whether I can consistently universalize the maxim 'I may break my promises only when.....', the gap can be filled by a description devised so that it will apply to my present circumstances, but to very few others.
     From: comment on Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Alasdair MacIntyre - A Short History of Ethics Ch.14
     A reaction: Another good objection to Kant. There is just a huge problem with how you state the maxim under discussion. One man's 'terrorist' is another man's 'freedom fighter'. 'Do everything possible to implement the will of God'.
Suicide, false promises, neglected talent, and lack of charity all involve contradictions of principle [Kant, by PG]
     Full Idea: Kant's four illustrations of the Categorical Imperative are: the contradiction of suicide, the contradiction of false promises, the contradiction of neglecting your talents, and the contradiction of neglecting charity.
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 422.53) by PG - Db (ideas)
Always treat yourself and others as an end, and never simply as a means [Kant]
     Full Idea: Act in such a way that you always treat humanity whether in your own person or in the person of any other, never simply as a means, but always at the same time as an end.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], AA429 p.96), quoted by Terry Pinkard - German Philosophy 1760-1860 02
     A reaction: This sets up the Kingdom of Ends. Note that this does not prohibit using people as a means. It just asks you to respect waiters and shop assistants. It seems to say you should not treat 'your own person' merely as a means. Prostitution?
Morality is the creation of the laws that enable a Kingdom of Ends [Kant]
     Full Idea: Morality consists in the relation of all action to the making of laws whereby alone a kingdom of ends is possible.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], AA434 p.102), quoted by Terry Pinkard - German Philosophy 1760-1860 02
     A reaction: Each individual gives themselves a law in the categorical imperative. Presumably the kingdom of ends is the convergence of these laws, because the categorical imperative has to be rational.
23. Ethics / D. Deontological Ethics / 5. Persons as Ends
Rational beings necessarily conceive their own existence as an end in itself [Kant]
     Full Idea: Rational nature exists as an end in itself; this is the way in which a man necessarily conceives his own existence.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 429.66)
The maxim of an action is chosen, and not externally imposed [Kant, by Bowie]
     Full Idea: Kant does not dictate what the maxim (the principle) of my action should be, and this is the crux. The individual has to decide the basis for their actions, rather than have it imposed on them, which differentiates us from the world of nature.
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Andrew Bowie - German Philosophy: a very short introduction 1
     A reaction: Apparenty this inspired the Romantic era (the Age of Freedom?) just as much as the French Revolution. It is the chief doctrine of extreme individualism - except that the maxim chosen should be one on which rational beings should agree.
Always treat humanity as an end and never as a means only [Kant]
     Full Idea: Act so that you treat humanity, whether in your own person or that of another always as an end and never as a means only.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]), quoted by Gordon Graham - Eight Theories of Ethics Ch.6
     A reaction: Does this really mean that I can't just negligently buy a newspaper without making an effort to respect its seller? How do I ensure that I treat myself as an end, and don't slip into treating myself as a means? What would that be like? Prostitution?
23. Ethics / D. Deontological Ethics / 6. Motivation for Duty
Only a good will makes us worthy of happiness [Kant]
     Full Idea: A good will seems to constitute the indispensable condition of our very worthiness to be happy.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 393.2)
The function of reason is to produce a good will [Kant]
     Full Idea: Since reason has been imparted to us as a practical power, which thus influences the will, its true function must be to produce a will which is good.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 396.7)
For Kant, even a person who lacks all sympathy for others still has a motive for benevolence [Kant, by Hursthouse]
     Full Idea: Kant, we may suppose, would say that if a man were 'cold in temperament and indifferent to the sufferings of others', he would still find in himself a source that would enable him to do what is benevolent.
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Rosalind Hursthouse - On Virtue Ethics Ch.4
     A reaction: This identifies a strong appeal of Kant's theory - that whether we are morally good should not be a matter of luck in our upbringing or natural temperament. How is the vicious person to be saved, if not by reason?
If we are required to give moral thought the highest priority, this gives morality no content [Williams,B on Kant]
     Full Idea: The Kantian view of what is important is that people should give moral considerations the highest deliberative priority, which Hegel attacked because it gives moral thought no content.
     From: comment on Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Bernard Williams - Ethics and the Limits of Philosophy Ch.10
     A reaction: Interesting. This points towards empathy and compassion as motivators, rather than reason, because there is some content to the morality, which calls out to us.
If Kant lives by self-administered laws, this is as feeble as self-administered punishments [Kierkegaard on Kant]
     Full Idea: Kant thought that man is his own law - he binds himself under the law which he gives himself. This is how lawlessness or experimentation is established. This is no more rigorously earnest than Sancho Panza's self-administered blows to his own ass.
     From: comment on Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Søren Kierkegaard - The Journals of Kierkegaard JP-I, 188
     A reaction: It really is tempting to go easy on yourself rather than on others. Kant had the right ideas, but human beings aren't as disciplined as the categorical imperative requires. [SY]
Our inclinations are not innately desirable; in fact most rational beings would like to be rid of them [Kant]
     Full Idea: Inclinations, as a source of needs, are so far from having an absolute value to make them desirable for their own sake that it must rather be the universal wish of every rational being to be wholly free from them.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 428.65)
Actions where people spread happiness because they enjoy it have no genuine moral worth [Kant]
     Full Idea: There are many spirits of so sympathetic a temper that they find an inner pleasure in spreading happiness around them. ..I maintain that an action of this kind, however right and amiable it may be, has still no genuinely moral worth.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], p.66)
     A reaction: We understand what he means (that principle is everything), but this still seems a big hole in his account, one which drives us to Aristotle's sensible views about what a nice person is really like.
24. Political Theory / A. Basis of a State / 3. Natural Values / c. Natural rights
Rational beings have a right to share in the end of an action, not just be part of the means [Kant]
     Full Idea: A violator of the rights of man intends to use the person of others merely as a means, not considering that they should be used only as beings who must themselves be able to share in the end of the very same action.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 430.68)
25. Social Practice / A. Freedoms / 4. Free market
Kant is the father of the notion of exploitation as an evil [Kant, by Berlin]
     Full Idea: Kant is the father of the notion of exploitation as an evil.
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Isaiah Berlin - The Roots of Romanticism Ch.3
     A reaction: This is central to the idea of Kant as the main father of liberalism, the idea that every individual deserves respect, and hence has rights. The idea would also be a crucial element in Europe turning against slavery.
25. Social Practice / D. Justice / 2. The Law / c. Natural law
Kant completed Grotius's project of a non-religious basis for natural law [Scruton on Kant]
     Full Idea: Kant is often held to have completed a task begun by Grotius, giving a basis for natural law which does not invoke the will of God, but rather commands God himself to obedience.
     From: comment on Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Roger Scruton - A Dictionary of Political Thought 'Kant'
     A reaction: This project, if successful, would clinch the naturalistic response to the Euthyphro Question (Ideas 336 and 337). It is a key issue for atheists, who generally wish to deny that their lack of religion leads inevitably to amorality.
25. Social Practice / D. Justice / 3. Punishment / b. Retribution for crime
Retributive punishment is better than being sent to hospital for your crimes [Kant, by Berlin]
     Full Idea: Kant believed in retributive punishment, because he thought that a man would prefer being sent to prison to going to hospital.
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Isaiah Berlin - The Roots of Romanticism Ch.4
     A reaction: That is, even criminals welcome the dignity of being treated as if they are actually responsible for their deeds, and are not just victims of inner forces. Criminals demand free will! Truth is best, though; many of them are not responsible at all.
25. Social Practice / F. Life Issues / 6. Animal Rights
Non-rational beings only have a relative value, as means rather than as ends [Kant]
     Full Idea: Beings whose existence depends not on our will but on nature have, if they are non-rational beings, only a relative value as means and are consequently called 'things' (rather than 'persons').
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 428.65)
     A reaction: Ugh. Is there nothing in between 'persons' and 'things'? How about a deeply comatose human, or an embryo? It is a gross distortion to think of a chimpanzee as a 'thing'.
26. Natural Theory / C. Causation / 1. Causation
Modern accounts of causation involve either processes or counterfactuals [Baron/Miller]
     Full Idea: The two major contemporary theories of causation are process theories and counterfactual theories. …Process theories treat it as something to be discovered. …Counterfactual theories ignore processes, and treat it in terms of truth and falsity.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 6.1)
     A reaction: I take the counterfactual theory to be a specialised branch of the project of analytic metaphysics, which seeks the logical form of causation sentences, using possible worlds semantics. In the real word its processes or nothing.
26. Natural Theory / C. Causation / 4. Naturalised causation
The main process theory of causation says it is transference of mass, energy, momentum or charge [Baron/Miller]
     Full Idea: According to contemporary process theories of causation it consists of the transference of a 'mark', which is always some conserved quantity. Candidates (from science) are mass, energy, momentum and electric charge.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 6.2.2)
     A reaction: Given my commitment to physicalism, this is my preferred theory of causation. It began with the suggestion of energy-transfer, but has broadened into the present idea. It is an updated version of the Newton view, as the meeting of objects.
If causes are processes, what is causation by omission? (Distinguish legal from scientific causes?) [Baron/Miller]
     Full Idea: Process theories of causation face a serious problem, such as killing a plant by failing to water it - a cause by omission. …Defenders of the theory propose two concepts of causation: one for legal and one for scientific contexts.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 6.2.3)
     A reaction: Not much of a problem, I think. Clearly the scientific concept has priority. The plant died of dehydration, resulting from the consumption and evaporation of the available water. The human causes of that situation are legion.
26. Natural Theory / C. Causation / 9. General Causation / c. Counterfactual causation
The counterfactual theory of causation handles the problem no matter what causes actually are [Baron/Miller]
     Full Idea: The chief advantage of the counterfactual theory of causation is that it is flexible enough to handle causation no matter what in the world underlies the causal facts in question.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 6.3)
     A reaction: It has this advantage because it makes no attempt to explain causation, but merely gives an accurate map of the truth and falsity of causal statements. It describes how we think about causation.
Counterfactual theories struggle with pre-emption by a causal back-up system [Baron/Miller]
     Full Idea: Counterfactual theories of causation have difficulty accommodating pre-emption, which involves the existence of causal back-up systems that undermine counterfactual dependence.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 6.5)
     A reaction: E.g. If your stone hadn't broken the window first, my stone would have broken it instead. So in the nearest world the withholding of your stone doesn't save the window.
27. Natural Reality / A. Classical Physics / 2. Thermodynamics / d. Entropy
There is no second 'law' of thermodynamics; it just reflects probabilities of certain microstates [Baron/Miller]
     Full Idea: According to contemporary statistical mechanics the second law of thermodynamics is not really a law at all, but merely reflects to probabilities of certain microstates, conditional on local boundary conditions having certain properties.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 5.6.1)
     A reaction: A nice illustration of how metaphysicians have been seduced by the 'laws' of nature into falsely inferring all sorts of natural necessities. Entropy is normally assumed to be totally inevitable, because of some natural force. It's just a pattern.
27. Natural Reality / C. Space / 6. Space-Time
In relativity space and time depend on one's motion, but spacetime gives an invariant metric [Baron/Miller]
     Full Idea: While spatial and temporal distances in relativity depend on one's relative state of motion, spatiotemporal distances within Minkowski spacetime do not. It therefore provides an invariant metric for describing the distances between things.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 4.2)
     A reaction: I doubt whether this solves all the worries which philosophers have, about relativity giving an account of time which contradicts our concept of time in every other area of our understanding.
27. Natural Reality / D. Time / 1. Nature of Time / f. Eternalism
The block universe theory says entities of all times exist, and time is the B-series [Baron/Miller]
     Full Idea: The standard block universe theory combines EntityEverywhenism with the B-theory of time.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 1.4)
     A reaction: This is also known as 'eternalism'. These authors emphasise that there is an ontological commitment to the objects of past and future in eternalism, as well as the B-series view of the moments of time.
27. Natural Reality / D. Time / 1. Nature of Time / g. Growing block
How can we know this is the present moment, if other times are real? [Baron/Miller]
     Full Idea: According to the spotlight and growing block views, there is a single objectively present moment, and also other objectively existing moments. But then how do persons in those different moments know which one is present?
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 1.6)
     A reaction: [compressed example] This sceptical thought leads either towards Presentism (we know we are present because that's all there is), or Eternalism (there is no present moment, so no problem). A good objection to spotlight and growing block.
If we are actually in the past then we shouldn't experience time passing [Baron/Miller]
     Full Idea: If the past really exists, and we are in it, rather than in the present, then we should rationally conclude that we are not experiencing the passage of time. …But then we have no basis for arguing that time is dynamic.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 1.6)
     A reaction: [compressed] It is certainly difficult to conceive how past times and entities could be real in every way, except that the experience of time passing has been removed. But if past people experience passing, they must believe they are present…
27. Natural Reality / D. Time / 1. Nature of Time / h. Presentism
Erzatz Presentism allows the existence of other times, with only the present 'actualised' [Baron/Miller]
     Full Idea: The 'erzatz presentism' view is that either the past and present exist, or all times exist, but only the present is 'actualised'. Standard Presentism says no times exist other than the present.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 1.7.2)
     A reaction: Ersatz presentism is obviously a close relative of the moving spotlight and growing block views. No account seems possible of the distinction between 'exists' and 'actualised' (other than the former being a mere abstract concept).
How do presentists explain relations between things existing at different times? [Baron/Miller]
     Full Idea: A chief challenge facing presentism is how to give an account of cross-temporal relations, which link things that exist with things that do not.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 2.2)
     A reaction: The problem of whether to keep a dubious death-bed promise is a bit of a puzzle for all of us, whatever our metaphysical view of time. None of us deny the reality of our great-great-grandparents.
Presentism needs endurantism, because other theories imply most of the object doesn't exist [Baron/Miller]
     Full Idea: Presentism is more naturally paired with endurantism, since if we pair it with perdurantism or transdurantism we have to say that most of any persisting object does not exist, and while that is not incoherent it is not very attractive.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 7.2.2)
     A reaction: (I think perdurance is time slices, and transdurance is the complete time worm). My preferred combination is this one: all that exists is the complete objects at the present moment. It also needs strong commitment to the truth of tensed verbs.
How can presentists move to the next future moment, if that doesn't exist? [Baron/Miller]
     Full Idea: If Presentism is true, how do we manage to travel from this moment to the next moment, a moment that is, at present, a future and hence non-existent moment?
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 8.3.1)
     A reaction: The reply would have to be that the metaphor of 'travel' is inappropriate for the movement through time. Travel needs a succession of existing places. The advancement of time is nothing like that. Nice question, though.
27. Natural Reality / D. Time / 1. Nature of Time / i. Denying time
Most of the sciences depend on the concept of time [Baron/Miller]
     Full Idea: Without time it is hard to make sense of historical research, evolutionary biology, psychology, chemistry, biology, cosmology, social science, archaeology, practical reason, evidence, human agency and causation.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 1.8)
     A reaction: [compressed] I do find it extraordinary that relativistic physicists cheerfully embrace an eternalist theory of time which seems to render nearly all of the other sciences meaningless.
27. Natural Reality / D. Time / 2. Passage of Time / a. Experience of time
For abstractionists past times might still exist, althought their objects don't [Baron/Miller]
     Full Idea: If past moments are seen as abstract (rather than concrete) it doesn't follow that because past objects no longer exist that therefore past times do not exist. The abstractionist needs to say which times are concretely realised.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 1.7.2)
     A reaction: Abstractionists see times as representations of change, rather than as substances.
The error theory of time's passage says it is either a misdescription or a false inference [Baron/Miller]
     Full Idea: According to the cognitive error theory of the passage of time, …it is either our misdescription of our temporal phenomenology, or some mechanism of our brain infers that the phenomenology is caused by time actually passing.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 3.3.1)
     A reaction: [compressed] I think I have some sympathy with the misdescription view. If you imaginatively gradually remove all the changing events in your experience, that doesn't end with a raw experience of pure time, because there is no such thing.
27. Natural Reality / D. Time / 2. Passage of Time / b. Rate of time
It is meaningless to measure the rate of time using time itself, and without a rate there is no flow [Baron/Miller]
     Full Idea: It seems we are forced to measure the rate of time's passing against itself. But that's just not a meaningful rate. So time has no rate. So it doesn't flow. So there is no such thing as temporal passage.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 2.3.1)
     A reaction: It is suggested that you can exchange dollars one for one, so time might move at one second per second. But you can't exchange your own dollars with yourself at one-for-one. That is meaningless. Time is NOT a substance which flows.
27. Natural Reality / D. Time / 2. Passage of Time / d. Time series
The C-series rejects A and B, and just sees times as order by betweenness, without direction [Baron/Miller]
     Full Idea: The C-series sees times not as directed, but as unchanging, and ordered in terms of the betweenness relation. The C-theory also asserts that the A-series and B-series do not exist.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 1.2)
     A reaction: This is McTaggart's idea. Compare this with A-series ordering by past, present and future, and B-series ordering by earlier-than, later-than and simultaneous. The main point is that A and B have a direction, but C does not.
27. Natural Reality / D. Time / 2. Passage of Time / e. Tensed (A) series
The A-series has to treat being past, present or future as properties [Baron/Miller]
     Full Idea: One of the limitations of the A-series is that temporal passage then presupposes the existence of properties of being present, being past and being future.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 2.1)
     A reaction: Metaphysicians happily talk about 'properties' all the time, and most of them never grasp how ambiguous and obscure that concept is. The idea that my recent scratching of my chin first acquired the 'present' property and then lost it is incoherent.
27. Natural Reality / D. Time / 2. Passage of Time / f. Tenseless (B) series
The B-series can have a direction, as long as it does not arise from temporal flow [Baron/Miller]
     Full Idea: The view that time has a direction is entirely consistent with the B-theory of time, as long as time's having a direction is not a matter of it having temporal flow.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 5.5)
     A reaction: I'm not sure how you could account for an intrinsic direction to time if it is not because of the 'flow'. The B-series seems to invite a reductive account of time's direction (e.g. to entropy).
27. Natural Reality / D. Time / 2. Passage of Time / g. Time's arrow
Static theories cannot account for time's obvious asymmetry, so time must be dynamic [Baron/Miller]
     Full Idea: One argument for the dynamic theory of time is that time is, obviously, asymmetric, and as static theories can't account for this asymmetry, we ought to posit temporal passage to explain it.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 5)
     A reaction: The B-series view (unlike the C-series) asserts that there is an order from past to future, but it offers no explanation of that fact. Physicists love to tell you the order could be in either direction, But why an 'order' at all?
The direction of time is either primitive, or reducible to something else [Baron/Miller]
     Full Idea: Primitivism is the view that time has a direction, and that its having that direction is intrinsic to time itself. Reductionism is the view that time has a direction, but its having that direction is reducible to something else.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 5.3.1)
     A reaction: The general suggestion for the second theory is that time's direction reduces to some aspect of the laws of nature. I strongly incline to the primitive view. Something's got to be primitive.
The kaon does not seem to be time-reversal invariant, unlike the rest of nature [Baron/Miller]
     Full Idea: The laws of nature are time-reversal invariant, with the small exception of the kaon (a type of sub-atomic particle)
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 5.3.2)
     A reaction: If that fact about the kaon were very secure indeed, then that would mean the collapse of the claims about the time-invariance of the laws. Since time-invariance is still routinely asserted, I assume it is not secure.
Maybe the past is just the direction of decreasing entropy [Baron/Miller]
     Full Idea: We could say that what we call the past is just the direction towards (for instance) decreasing entropy, and the direction we call the future is the direction towards increasing entropy.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 5.3.3)
     A reaction: One problem is that locally entropy can sometimes go the other way, which would imply local pockets with a reversed time's arrow,.
We could explain time's direction by causation: past is the direction of causes, future of effects [Baron/Miller]
     Full Idea: An option for accounting for the direction of time would be to appeal to the direction of causation …to the future is the direction towards which there are effects, and the past is the direction towards which there are causes.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 5.6.2)
     A reaction: The obvious problem is that we can no longer pick out a cause by saying it 'precedes' its effect. It is not obvious what other criterion can be used to distinguish them (esp. given Hume's regularity account).
27. Natural Reality / D. Time / 2. Passage of Time / h. Change in time
Static time theory presents change as one property at t1, and a different property at t2 [Baron/Miller]
     Full Idea: The static theory of time appeals to an 'at-at' notion of change, which analyses change as objects or events having one property at time t1, and a different property at t2. (The worry about this is that it describes variation, but not real change).
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 1.4)
     A reaction: I suppose observing a different property at t2 is observing the result of a change, rather than the process. But then the process might be broken down into micro-gradations of properties. Maybe only results can be observed.
27. Natural Reality / D. Time / 2. Passage of Time / j. Time travel
If a time traveller kills his youthful grandfather, he both exists and fails to exist [Baron/Miller]
     Full Idea: It is surely true that if a time traveller travels back in time and succeeds in shooting his youthful grandfather then the time traveller both exists and fails to exist.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 8.2)
     A reaction: This is the best known paradox of time travel. It is a special dramatic case of making any change to the past. If the traveller kills his neighbour's grandfather, his neighbour should vanish. Moving a speck of dust could have enduring results.
Presentism means there no existing past for a time traveller to visit [Baron/Miller]
     Full Idea: A time traveller can only travel to a location if the location exists, But if Presentism is true then past locations do not exist, so time travel to the past is impossible.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 8.3.1)
     A reaction: Might a time machine actually restore the past time which had ceased to exist? Then the problem is the information needed to achieve that.
27. Natural Reality / D. Time / 2. Passage of Time / k. Temporal truths
The past (unlike the future) is fixed, along with truths about it, by the existence of past objects [Baron/Miller]
     Full Idea: It is the existence of past objects that explains why the past is fixed, and why there are truths about the past, and it is the non-existence of future objects that explains why the future is malleable.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 1.3)
     A reaction: The authors label this view 'EntityNowandThenism', and it comes in a section on the 'Temporal Ontology'.
27. Natural Reality / D. Time / 3. Parts of Time / e. Present moment
The moving spotlight says entities can have properties of being present, past or future [Baron/Miller]
     Full Idea: The moving spotlight theorist maintains that there are special temporal properties that entities possess, namely the properties of being present, being past and being future.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 1.5.3)
     A reaction: Are these thought to be intrinsic properties of the objects, or (more plausibly) relational properties, between objects and times? Either view is weird. Does some godlike part of time scurry along, illuminating things, like a mouse under a carpet?
The present moment is a matter of existence, not of acquiring a property [Baron/Miller]
     Full Idea: Rather than treating presentness as an acquired property …. presentism equates the metaphysical specialness of the present with existence.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 2.2)
     A reaction: It seems like common sense to say that the recent scratching of my chin came into existence and then went out of existence (rather than that it acquired and then lost a property).
28. God / A. Divine Nature / 6. Divine Morality / b. Euthyphro question
We judge God to be good by a priori standards of moral perfection [Kant]
     Full Idea: Where do we get the concept of God as the highest good? Solely from the idea of moral perfection, which reason traces a priori.
     From: Immanuel Kant (Groundwork of the Metaphysic of Morals [1785], 408.29)
We can only know we should obey God if we already have moral standards for judging God [Kant, by MacIntyre]
     Full Idea: On Kant's view it never follows that we ought to do what God commands, for we would have to know that we always ought to do what God commands, but that would need a standard of moral judgement independent of God's commands. God's commands are redundant.
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Alasdair MacIntyre - After Virtue: a Study in Moral Theory Ch.4
     A reaction: This strikes me as a very powerful argument, even an undeniable one. How could you accept any authority if you didn't have some standards for accepting it, even if the standard was just to be awestruck by someone's charisma and will-power?
28. God / B. Proving God / 2. Proofs of Reason / c. Moral Argument
God is not proved by reason, but is a postulate of moral thinking [Kant, by Davies,B]
     Full Idea: Kant speaks of God not as something known or proved to exist by virtue of rational argument, but as a postulate of moral reflection (that is, of 'practical reason').
     From: report of Immanuel Kant (Groundwork of the Metaphysic of Morals [1785]) by Brian Davies - Introduction to the Philosophy of Religion 9 'Morality'
     A reaction: Presumably it is a necessary postulate, which makes this a transcendental argument, surely?
