64 ideas

1. Philosophy / A. Wisdom / 1. Nature of Wisdom
Wisdom is knowing the highest good, and conforming the will to it [Kant]
     Full Idea: Wisdom, theoretically regarded, means the knowledge of the highest good and, practically, the conformability of the will to the highest good.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.II.II.V)
     A reaction: This seems a narrow account of wisdom, focusing entirely on goodness rather than truth. A mind that valued nothing but understood everything would have a considerable degree of wisdom, in the normal use of that word.
1. Philosophy / D. Nature of Philosophy / 3. Philosophy Defined
What fills me with awe are the starry heavens above me and the moral law within me [Kant]
     Full Idea: Two things fill the mind with ever new and increasing wonder and awe, the oftener and the more steadily we reflect on them: the starry heavens above me and the moral law within me.
     From: Immanuel Kant (Critique of Practical Reason [1788], Concl)
     A reaction: I am beginning to think that the two major issues of all philosophy are ontology and metaethics, and Kant is close to agreeing with me. He certainly wasn't implying that astronomy was a key aspect of philosophy.
1. Philosophy / D. Nature of Philosophy / 5. Aims of Philosophy / e. Philosophy as reason
Consistency is the highest obligation of a philosopher [Kant]
     Full Idea: Consistency is the highest obligation of a philosopher and yet the most rarely found.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.1.1.§3)
     A reaction: I agree with this, and it also strikes me as the single most important principle of Kant's philosophy, which is the key to his whole moral theory.
1. Philosophy / E. Nature of Metaphysics / 5. Metaphysics beyond Science
Metaphysics is just a priori universal principles of physics [Kant]
     Full Idea: Metaphysics only contains the pure a priori principles of physics in their universal import.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.II.II.VI)
     A reaction: 'Universal' seems to imply 'necessary'. If you thought that no a priori universal principles were possible, you would be left with physics. I quite like the definition, except that I think there would still be metaphysics even if there were no physics.
3. Truth / C. Correspondence Truth / 3. Correspondence Truth critique
The only way to specify the corresponding fact is asserting the sentence [Williams,M]
     Full Idea: The trouble with appeal to facts in the correspondence theory is that, in general, we have no way of indicating what fact a sentence, when true, corresponds to other than asserting the sentence.
     From: Michael Williams (Problems of Knowledge [2001], Ch.12)
3. Truth / D. Coherence Truth / 1. Coherence Truth
Coherence needs positive links, not just absence of conflict [Williams,M]
     Full Idea: It is often claimed that coherence is more than 'absence of conflict' between beliefs; it also involves 'positive connections'.
     From: Michael Williams (Problems of Knowledge [2001], Ch.10)
Justification needs coherence, while truth might be ideal coherence [Williams,M]
     Full Idea: Contemporary coherence theorists are advancing a theory of justification, not of truth, …with those who argue that truth is also coherence explaining it in terms of ideal coherence, or coherence at the limit of enquiry.
     From: Michael Williams (Problems of Knowledge [2001], Ch.10)
5. Theory of Logic / A. Overview of Logic / 3. Value of Logic
Deduction shows entailments, not what to believe [Williams,M]
     Full Idea: The rules of deduction are rules of entailment, not rules of inference. They tell us what follows from what, not what to believe on the basis of what.
     From: Michael Williams (Problems of Knowledge [2001], Ch.18)
10. Modality / A. Necessity / 11. Denial of Necessity
There is no necessity higher than natural necessity, and that is just regularity [Quine]
     Full Idea: In principle I see no higher or more austere necessity than natural necessity; and in natural necessity, or our attribution of it, I see only Hume's regularities
     From: Willard Quine (Necessary Truth [1963], p.76)
     A reaction: Presumably this allows logical necessity as a 'lower' necessity, but denies 'metaphysical' necessity, in line with Hume and other tough empiricists. Personally I adore metaphysical necessities, but they are a bit hard to establish conclusively.
10. Modality / C. Sources of Modality / 1. Sources of Necessity
Necessity cannot be extracted from an empirical proposition [Kant]
     Full Idea: It is a clear contradiction to try to extract necessity from an empirical proposition.
     From: Immanuel Kant (Critique of Practical Reason [1788], Pref)
     A reaction: This is precisely the idea which Kripke challenged, claiming that the necessary essences of natural kinds such as gold have to be discovered empirically. All my intuitions are with Kant (and Hume) on this, but it is a complex issue…
11. Knowledge Aims / A. Knowledge / 4. Belief / a. Beliefs
We could never pin down how many beliefs we have [Williams,M]
     Full Idea: Asking how many beliefs I have is like asking how many drops of water there are in a bucket. If I believe my dog is in the garden, do I also believe he is not in the house, or in Siberia?
     From: Michael Williams (Problems of Knowledge [2001], Ch.11)
11. Knowledge Aims / B. Certain Knowledge / 1. Certainty
Propositions make error possible, so basic experiential knowledge is impossible [Williams,M]
     Full Idea: Propositional content is inseparable from possible error. Therefore no judgement, however modest, is indubitable. So if basic experiential knowledge has to be indubitable, there is no such knowledge.
     From: Michael Williams (Problems of Knowledge [2001], Ch. 8)
11. Knowledge Aims / C. Knowing Reality / 2. Phenomenalism
Phenomenalism is a form of idealism [Williams,M]
     Full Idea: Phenomenalism is a form of idealism.
     From: Michael Williams (Problems of Knowledge [2001], Ch.12)
12. Knowledge Sources / B. Perception / 4. Sense Data / a. Sense-data theory
Sense data avoid the danger of misrepresenting the world [Williams,M]
     Full Idea: The point of insisting on the absolute immediacy of sense data is that representation always seems to involve the possibility of misrepresentation.
     From: Michael Williams (Problems of Knowledge [2001], Ch. 8)
12. Knowledge Sources / B. Perception / 4. Sense Data / d. Sense-data problems
Sense data can't give us knowledge if they are non-propositional [Williams,M]
     Full Idea: Acquaintance with sense data is supposed to be a form of non-propositional knowledge, but how can something be non-propositional and yet knowledge?
     From: Michael Williams (Problems of Knowledge [2001], Ch. 8)
13. Knowledge Criteria / A. Justification Problems / 1. Justification / a. Justification issues
Is it people who are justified, or propositions? [Williams,M]
     Full Idea: What exactly is supposed to be 'justified': a person's believing some particular proposition, or the proposition that he believes?
     From: Michael Williams (Problems of Knowledge [2001], Ch. 1)
     A reaction: A key distinction. See my comment on Idea 3752. What would justify a sign saying 'treasure buried here'? People can be justified in believing falsehoods. How could a false proposition be justified?
13. Knowledge Criteria / B. Internal Justification / 2. Pragmatic justification
What works always takes precedence over theories [Williams,M]
     Full Idea: A theory that represents working practices as unworkable is a bad theory.
     From: Michael Williams (Problems of Knowledge [2001], Ch.13)
     A reaction: Good point. There's a lot of this about in epistemology, especially accusations of circularity or infinite regress, which (if true) don't somehow seem to worry the cove on the Clapham omnibus.
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / b. Basic beliefs
Experience must be meaningful to act as foundations [Williams,M]
     Full Idea: If we are to treat experience as the foundation of knowledge, then experience must itself be understood to involve propositional content.
     From: Michael Williams (Problems of Knowledge [2001], Ch. 8)
     A reaction: This sounds right, but since pure 'experience' obviously doesn't have propositional content, because it needs interpretation and evaluation, then this strategy won't work.
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / c. Empirical foundations
Are empirical foundations judgements or experiences? [Williams,M]
     Full Idea: Empirical foundationists must decide whether knowledge ultimately rests on either beliefs or judgements about experience, or on the experiences or sensations themselves.
     From: Michael Williams (Problems of Knowledge [2001], Ch. 8)
     A reaction: This clarifies the key issue very nicely, and I firmly vote for the former option. The simplest point is that error is possible about what sensations are taken to be of, so they won't do on their own.
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / f. Foundationalism critique
Foundationalists are torn between adequacy and security [Williams,M]
     Full Idea: The foundationalists dilemma is to define a basis for knowledge modest enough to be secure but rich enough to be adequate.
     From: Michael Williams (Problems of Knowledge [2001], Ch. 7)
     A reaction: ..And that is just what they are unable to do, precisely because adequate support would have to have enough content to be defeasibe or fallible.
Strong justification eliminates error, but also reduces our true beliefs [Williams,M]
     Full Idea: A strongly justificationist view of rationality may not be so rational; we want the truth, but avoiding all errors and maximising our number of true beliefs are not the same thing.
     From: Michael Williams (Problems of Knowledge [2001], Ch. 7)
     A reaction: An interesting dilemma - to avoid all errors, believing nothing; to maximise true belief, believe everything. It is rational to follow intuition, guesses, and a wing and a prayer - once you are experienced and educated.
13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / c. Coherentism critique
Why should diverse parts of our knowledge be connected? [Williams,M]
     Full Idea: Why should political theory ever have much to do with quantum physics, or pet care with parliamentary history?
     From: Michael Williams (Problems of Knowledge [2001], Ch.11)
     A reaction: This hardly demolishes the coherence account of justification, since your views on pet care had better be coherent, for your pet's sake. It's a pity people can make their politics cohere with their ethics.
Coherence theory must give a foundational status to coherence itself [Williams,M]
     Full Idea: Coherence theory implicitly assigns the criteria of coherence a special status. …In so far as this status is assigned a priori, the coherence theory represents a rationalistic variant of foundationalism.
     From: Michael Williams (Problems of Knowledge [2001], Ch.11)
     A reaction: Nice move, to accuse coherence theorists of foundationalism! Wrong, though, because the a priori principles of coherence are not basic beliefs, but evolved pragmatic procedures (or something...).
13. Knowledge Criteria / C. External Justification / 1. External Justification
Externalism does not require knowing that you know [Williams,M]
     Full Idea: From an externalist point of view, knowing about one's reliability is not required for 'first-order' knowledge.
     From: Michael Williams (Problems of Knowledge [2001], Ch. 2)
     A reaction: Ah. 'First-order knowledge' - what's that? What we used to call 'true belief', I would say. Adequate for animals, and a good guide to daily life, but uncritical and unjustifiable.
Externalism ignores the social aspect of knowledge [Williams,M]
     Full Idea: A problem with pure externalism is that it ignores the social dimension of knowledge.
     From: Michael Williams (Problems of Knowledge [2001], Ch. 2)
     A reaction: This seems to be contradicted by Idea 3573, which allows a social dimension to agreement over what is reliable. I am inclined to take knowledge as an entirely social concept.
13. Knowledge Criteria / C. External Justification / 2. Causal Justification
In the causal theory of knowledge the facts must cause the belief [Williams,M]
     Full Idea: According to Goldman's early causal theory of knowledge, my belief that p counts as knowledge if and only if it is caused by the fact that p. This is sufficient as well as necessary, and so does not involve justification.
     From: Michael Williams (Problems of Knowledge [2001], Ch. 2)
     A reaction: I take his theory simply to be false because what causes a belief is not what justifies it. I expect my mother to ring; the phone rings; I 'know' it is my mother (and it is), because I strongly expect it.
How could there be causal relations to mathematical facts? [Williams,M]
     Full Idea: It is not clear what would even be meant by supposing that there are causal relations to mathematical facts.
     From: Michael Williams (Problems of Knowledge [2001], Ch. 2)
     A reaction: I agree, though platonists seem to be willing to entertain the possibility that there are causal relations, for which no further explanation can be given. Better is knowledge without a causal relation.
Only a belief can justify a belief [Williams,M]
     Full Idea: Justification requires logical rather than causal connections. That is the point of the slogan that only a belief can justify a belief.
     From: Michael Williams (Problems of Knowledge [2001], Ch.10)
     A reaction: It seems better to talk of 'rational' connections, rather than 'logical' connections. It isn't 'logical' to believe that someone despises me because their lip is faintly curled.
13. Knowledge Criteria / C. External Justification / 3. Reliabilism / a. Reliable knowledge
Externalist reliability refers to a range of conventional conditions [Williams,M]
     Full Idea: The radical externalists' key notion is 'reliability', which is a normative condition governing adequate performance, involving reference to a range of conditions which we decide rather than discover.
     From: Michael Williams (Problems of Knowledge [2001], Ch. 2)
     A reaction: If we can decide whether a source is reliable, we can also decide whether a reliable source has performed well on this occasion, and that will always take precedence.
13. Knowledge Criteria / C. External Justification / 3. Reliabilism / b. Anti-reliabilism
Sometimes I ought to distrust sources which are actually reliable [Williams,M]
     Full Idea: I may reach a belief using a procedure that is in fact reliable, but which I ought to distrust.
     From: Michael Williams (Problems of Knowledge [2001], Ch. 1)
     A reaction: The tramp on the park bench who gives good share tips. The clock that is finally working, but has been going haywire for weeks. Reliabilism is a bad theory.
13. Knowledge Criteria / C. External Justification / 5. Controlling Beliefs
We control our beliefs by virtue of how we enquire [Williams,M]
     Full Idea: We control our beliefs by virtue of how we enquire.
     From: Michael Williams (Problems of Knowledge [2001], Ch. 1)
13. Knowledge Criteria / D. Scepticism / 1. Scepticism
Scepticism just reveals our limited ability to explain things [Williams,M]
     Full Idea: All the sceptic's arguments show is that there are limits to our capacity to give reasons or cite evidence.
     From: Michael Williams (Problems of Knowledge [2001], Ch.13)
13. Knowledge Criteria / D. Scepticism / 2. Types of Scepticism
Scepticism can involve discrepancy, relativity, infinity, assumption and circularity [Williams,M]
     Full Idea: The classical Five Modes of Scepticism are Discrepancy (people always disagree), Relativity ('according to you'), Infinity (infinite regress of questions), Assumption (ending in dogma) and Circularity (end up where you started).
     From: Michael Williams (Problems of Knowledge [2001], Ch. 5)
     A reaction: I take Relativity to be different from scepticism (because, roughly, it says there is nothing to know), and the others go with Agrippa's Trilemma of justification, which may have solutions.
14. Science / A. Basis of Science / 1. Observation
Seeing electrons in a cloud chamber requires theory [Williams,M]
     Full Idea: Armed with enough theory, we can see electrons in a cloud chamber.
     From: Michael Williams (Problems of Knowledge [2001], Ch.10)
19. Language / A. Nature of Meaning / 7. Meaning Holism / a. Sentence meaning
Foundationalists base meaning in words, coherentists base it in sentences [Williams,M]
     Full Idea: In the foundationalist picture the meaning of individual words (defined ostensively) is primary, and that of sentences is derivative. For coherentists sentences come first, with meaning understood functionally or inferentially.
     From: Michael Williams (Problems of Knowledge [2001], Ch.10)
     A reaction: Coherentism about language doesn't imply coherentism about justification. On language I vote for foundationalism, because I am impressed by the phenomenon of compositionality.
20. Action / B. Preliminaries of Action / 2. Willed Action / a. Will to Act
Can pure reason determine the will, or are empirical conditions relevant? [Kant]
     Full Idea: This is the first question: Is pure reason sufficient of itself to determine the will, or is it only as empirically conditioned that it can do so?
     From: Immanuel Kant (Critique of Practical Reason [1788], Intro)
     A reaction: This seems to be the core question of intellectualism, which goes back to Socrates. You can only accept the question if you accept the concept of 'pure' reason. Values seem to be needed for action, as well as empirical circumstances.
The will is the faculty of purposes, which guide desires according to principles [Kant]
     Full Idea: The will could be defined as the faculty of purposes, since they are always determining grounds of the faculty of desire according to principles.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.1.II)
     A reaction: Do animals have wills? Kant implies that you can only have a will if you have principles. Compare Hobbes' rather less elevated definition of the will (Idea 2362).
20. Action / C. Motives for Action / 3. Acting on Reason / a. Practical reason
The sole objects of practical reason are the good and the evil [Kant]
     Full Idea: The sole objects of a practical reason are thus those of the good and the evil.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.1.II)
     A reaction: Of course, you may aim to achieve x because it is good, while I judge x to be evil.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / b. Rational ethics
Only human reason can confer value on our choices [Kant, by Korsgaard]
     Full Idea: Kant argues that only human reason is in a position to confer value on the objects of human choice.
     From: report of Immanuel Kant (Critique of Practical Reason [1788]) by Christine M. Korsgaard - Aristotle and Kant on the Source of Value 8 'Kant'
     A reaction: If the source of value is humans, then it is not immediately clear why it is only our reason that does the conferring. What is the status of a choice on which reason fails to confer value? The idea is that reason, unlike desire, has intrinsic value.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / h. Expressivism
People cannot come to morality through feeling, because morality must not be sensuous [Kant]
     Full Idea: In the subject there is no antecedent feeling tending to morality; that is impossible, because all feeling is sensuous, and the drives of the moral disposition must be free from every sensuous condition.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.1.III)
     A reaction: I'm not quite clear (even after reading Kant) why moral drives 'must' be free of sensuousness. Aristotle gives a much better account, when he tells us that the sensuous drives must be trained in the right way, and must be in harmony with the reason.
22. Metaethics / B. Value / 1. Nature of Value / f. Ultimate value
Kant may rate two things as finally valuable: having a good will, and deserving happiness [Orsi on Kant]
     Full Idea: In some interpretations it appears that for Kant two things are finally valuable: good will (unconditionally), and deserved happiness (conditionally on the value of good will).
     From: comment on Immanuel Kant (Critique of Practical Reason [1788]) by Francesco Orsi - Value Theory 2.2
     A reaction: It doesn't sound difficult to reconcile these two. Just ask 'what is required of someone to deserve happiness?'.
An autonomous agent has dignity [Würde], which has absolute worth [Kant, by Pinkard]
     Full Idea: For Kant, there is something about beings that can act autonomously that is itself of 'absolute worth', which Kant calls the 'dignity' [Würde] of each such agent.
     From: report of Immanuel Kant (Critique of Practical Reason [1788]) by Terry Pinkard - German Philosophy 1760-1860 02
     A reaction: This answers my puzzle about where Kant's fundamental values come from. Surely wicked actions can be autonomous? Autonomous actions aren't thereby good actions. A 'good' will, course, whatever that is. Rational? My problem with existentialist ethics.
The good will is unconditionally good, because it is the only possible source of value [Kant, by Korsgaard]
     Full Idea: Kant argues that the good will is unconditionally good because it is the only thing able to be a source of value.
     From: report of Immanuel Kant (Critique of Practical Reason [1788]) by Christine M. Korsgaard - Aristotle and Kant on the Source of Value 8 'Kant'
     A reaction: The obvious worry is the circularity of resting a theory of value on identifying a 'good' will as its source.
Good or evil cannot be a thing, but only a maxim of action, making the person good or evil [Kant]
     Full Idea: If something is held to be absolutely good or evil in all respects and without qualification, it could not be a thing but only the manner of acting, i.e., it could only be the maxim of the will, and consequently the acting person himself is good or evil.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.1.II)
     A reaction: It goes on to deny that pain is intrinsically evil, but his reason for the claim is not clear. Nevetheless, I think he is right. This remark is an important bridge between Enlightenment concerns with law and Greek concerns with character.
22. Metaethics / C. The Good / 1. Goodness / g. Consequentialism
Morality involves duty and respect for law, not love of the outcome [Kant]
     Full Idea: All the morality of actions may be placed in their necessity from duty and from respect for the law, and not from love for or leaning toward that which the action is to produce.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.1.III)
     A reaction: Kant tries to reject consequentialism, but you cannot assess your duty or the universal law without an assessment of probable consequences, and we could never choose between laws if we did not already see value in the outcome.
22. Metaethics / C. The Good / 2. Happiness / a. Nature of happiness
Our happiness is all that matters, not as a sensation, but as satisfaction with our whole existence [Kant]
     Full Idea: Our happiness is the only thing of importance, provided this is judged, as reason requires, not according to transitory sensation but according to the influence which this contingency has on our whole existence and our satisfaction with it.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.1.II)
     A reaction: This is closer to the Greek eudaimonia than to the modern conception of happiness, which is largely just a feeling. Kant's view seems more like a private judgement on your whole life, where the Greek idea seems more public and objective.
Happiness is the condition of a rational being for whom everything goes as they wish [Kant]
     Full Idea: Happiness is the condition of a rational being in the world with whom everything goes according to his wish and will.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.II.II.V)
     A reaction: For such a sophisticated and rational philosopher this seems a rather crude notion. Reluctant alcoholics don't fit. Bradley has a much better definition (Idea 5655).
22. Metaethics / C. The Good / 2. Happiness / c. Value of happiness
Morality is not about making ourselves happy, but about being worthy of happiness [Kant]
     Full Idea: Morality is not properly the doctrine of how we should make ourselves happy, but how we should become worthy of happiness.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.II.II.V)
     A reaction: Whatever else you think of Kant's moral theory, this remark is a clarion call we can all recognise. Suppose we all somehow ended up in a state of maximal happiness by systematically betraying one another.
23. Ethics / C. Virtue Theory / 1. Virtue Theory / a. Nature of virtue
The highest worth for human beings lies in dispositions, not just actions [Kant]
     Full Idea: The highest worth which human beings can and should procure for themselves lies in dispositions and not in actions only.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.1.II)
     A reaction: This leaves the problem of the well-meaning fool, who has wonderful dispositions but poor judgement. What Kant is describing here is better known as virtue. See Idea 58.
Virtue is the supreme state of our pursuit of happiness, and so is supreme good [Kant]
     Full Idea: Virtue (as the worthiness to be happy) is the supreme condition of whatever appears to us to be desirable and thus of all our pursuit of happiness and, consequently, the supreme good.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.II.II)
     A reaction: Thus Kant can claim to be a virtue theorist, but giving us a very different account of how virtue arises. He emphasises elsewhere (Idea 6197) that the supreme good must be in the will, not in the outcome. 'Virtue' is here a rather thin concept.
23. Ethics / C. Virtue Theory / 2. Elements of Virtue Theory / c. Motivation for virtue
Moral law is holy, and the best we can do is achieve virtue through respect for the law [Kant]
     Full Idea: The moral law is holy (unyielding), although all the moral perfection to which man can attain is still only virtue, that is, a rightful disposition arising from respect for the law.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.II.II.V)
     A reaction: In comparison with Aristotle's view of virtue this is very passive and external. Aristotle doesn't need laws for virtue, he needs inner harmony and a grasp of what has high value.
23. Ethics / D. Deontological Ethics / 3. Universalisability
No one would lend money unless a universal law made it secure, even after death [Kant]
     Full Idea: If my maxim is 'augment my property by all safe means', I can't make that a law allowing me to keep a dead man's loan, because no one would make a loan if that were the moral law.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.1.1.§4)
     A reaction: This is a simple illustration of Kant's strategy and it shows clearly how, for all his talk of 'pure reason', his moral law is strongly guided by consequences, and that these can only judged by prior values - for example, that loans are a good thing.
Universality determines the will, and hence extends self-love into altruism [Kant]
     Full Idea: The form of universality is itself the determining ground of the will, …and from this limitation alone, and not from the addition of any exernal drive, the concept of obligation arises to extend the maxim of self-love also to the happiness of others.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.1.1.§8)
     A reaction: This is the heroic and optimistic part of Kant's philosophy, the attempt to derive altruism from pure reason. The claim seems to be that maxims don't motivate until they have been universalised. I fear that only altruism could add such motivation.
23. Ethics / D. Deontological Ethics / 5. Persons as Ends
Everyone (even God) must treat rational beings as ends in themselves, and not just as means [Kant]
     Full Idea: In the order of ends, man (and every rational being) is an end in himself, i.e., he is never to be used merely as a means for someone (even for God) without at the same time being himself an end.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.II.II.V)
     A reaction: The worry here is that Kant has set up an exam that you have to pass before you can be treated as a moral end. Animals and the ecosystem will fail the exam, and even some human beings will be borderline cases. We should respect everything.
23. Ethics / D. Deontological Ethics / 6. Motivation for Duty
A holy will is incapable of any maxims which conflict with the moral law [Kant]
     Full Idea: A holy will is one which is incapable of any maxims which conflict with the moral law
     From: Immanuel Kant (Critique of Practical Reason [1788], I.1.1.§7)
     A reaction: If such a will is 'incapable' of conflicting with moral law, it will not need to think or assess before action. This means that Kant's moral ideal can ultimately exclude the free-thinking intellect. Kant is describing a state of true Aristotelian virtue.
Reason cannot solve the problem of why a law should motivate the will [Kant]
     Full Idea: How a law in itself can be the direct motive of the will (which is the essence of morality) is an insoluble problem for the human reason.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.1.III)
     A reaction: If that is the great man's final word, then it is tempting to switch to an empirical moral theory, such as that of Hobbes or Hume or E.O. Wilson, which starts from what motivations are available, and builds morality up from that.
25. Social Practice / F. Life Issues / 4. Suicide
A permanent natural order could not universalise a rule permitting suicide [Kant]
     Full Idea: The maxim of freely disposing of my life could not hold as a universal law of nature, …because no one could choose to end his life, for such an arrangement could not constitute a permanent natural order.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.1.1.I)
     A reaction: This sort of claim brings out the advantanges of Aristotelian 'particularism' (expounded by Dancy). Obviously universal suicide isn't promising, but no one wants that. A few suicides in extreme cases will have no effect at all on the natural order.
28. God / A. Divine Nature / 6. Divine Morality / b. Euthyphro question
Obligation does not rest on the existence of God, but on the autonomy of reason [Kant]
     Full Idea: It is not to be understood that the assumption of the existence of God is necessary as a ground for all obligation in general (for this rests, as has been shown, solely on the autonomy of reason itself).
     From: Immanuel Kant (Critique of Practical Reason [1788], I.II.II.V)
     A reaction: This shows that Kant agrees with Plato about the Euthyphro Question - that is, they both think that morality is logically and naturally prior to any gods. I agree. Why would we admire or worship or obey gods if we didn't think they were good?
28. God / B. Proving God / 2. Proofs of Reason / c. Moral Argument
We have to postulate something outside nature which makes happiness coincide with morality [Kant]
     Full Idea: The existence must be postulated of a cause of the whole of nature, itself distinct from nature, which contains the ground of the exact coincidence of happiness with morality.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.II.II.V)
     A reaction: I can see that we need a concept of how happiness could be made proportional to morality, but I can't make sense of the assumption that it is actually possible, and hence something must exist that would achieve it.
Belief in justice requires belief in a place for justice (heaven), a time (eternity), and a cause (God) [Kant, by PG]
     Full Idea: To believe in justice in an unjust world, you have to believe in a place of perfect justice (heaven), a time for perfect justice (eternity), and a cause of perfect justice (God).
     From: report of Immanuel Kant (Critique of Practical Reason [1788], I.II.II.V) by PG - Db (ideas)
     A reaction: Compare Boethius in Idea 5765. I can see that we might need to grasp the ideals of eternal justice in order to understand morality, but belief in their genuine possibility, or even actuality, doesn't seem to follow.
28. God / B. Proving God / 3. Proofs of Evidence / a. Cosmological Proof
To know if this world must have been created by God, we would need to know all other possible worlds [Kant]
     Full Idea: We can't infer the existence of God from knowledge of this world, because we should have to know all possible worlds in order to compare them - in short, we should have to be omniscient - in order to say that it is possible only through a God.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.II.II.VI)
     A reaction: A nice remark, but not wholly convincing. This argument would block all attempts to work out necessities a priori, such as those of maths and logic. Must we know all possible worlds intimately to know that 2+2 is always 4?
28. God / B. Proving God / 3. Proofs of Evidence / c. Teleological Proof critique
Using God to explain nature is referring to something inconceivable to explain what is in front of you [Kant]
     Full Idea: To have recourse to God in explaining the arrangements of nature is not a physical explanation but a confession that one has come to the end of philosophy, since one assumes something of which one has no concept to conceive what is before one's eyes.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.II.II.VI)
     A reaction: Hume had many objections to the design argument, some of them positively sarcastic, but none as ruthless as this, since Kant (here) seems to find God to be a totally empty concept, and hence a complete non-starter as explanation for anything.
From our limited knowledge we can infer great virtues in God, but not ultimate ones [Kant]
     Full Idea: Since we know only a small part of the world, and cannot compare it with all possible worlds, we can infer from the order, design and magnitude to a wise, beneficent and powerful Author, but not that He is all-knowing, all-good, and all-powerful.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.II.II.VI)
     A reaction: This is very much in the spirit of David Hume, who inferred from the flaws in the world that God did not seem to be entirely competent. Hume is also more imaginative, in seeing that God might be a committee, or a hired workman.
28. God / C. Attitudes to God / 4. God Reflects Humanity
In all naturalistic concepts of God, if you remove the human qualities there is nothing left [Kant]
     Full Idea: One can confidently challenge all pretended natural theologians to cite one single definitive attribute of their object, of which one could not irrefutably show that, when everything anthropomorphic is removed, only the word remains.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.II.II.VI)
     A reaction: This idea derives from Hume's very empiricist view of our understanding of God (Idea 2185), but Kant is (remarkably) more hostile than Hume, because he actually implies that most people's concept of God is totally vacuous.
