| 21422 | Moral self-knowledge is the beginning of all human wisdom [Kant] |
| Full Idea: Moral self-knowledge, which seeks to penetrate into the depths (the abyss) of one's heart that are quite difficult to fathom, is the beginning of all human wisdom. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 441 I.I) | |
| A reaction: I'm not clear what I am supposed to be looking for on this quest. I'm guessing that being completely honest about one's own maxims in moral action would be a good start. And maybe confronting one's murkier desires. |
| 21408 | For any subject, its system of non-experiential concepts needs a metaphysics [Kant] |
| Full Idea: A philosophy of any subject (a system of rational knowledge from concepts) requires a system of pure rational concepts independent of any conditions of intuition, that is, a metaphysics. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 375 Pref) | |
| A reaction: 'Pure rational concepts' must be a priori, and (in Kant's case) transcendental - i.e. discovered from the study of presuppositions. Does this actually say that the philosophies of science, biology, psychology, economics etc each needs a metaphysics? |
| 17729 | Examining concepts can recover information obtained through the senses [Jenkins] |
| Full Idea: My idea is that conceptual examination might be a way of recovering information previously obtained through the senses. | |
| From: Carrie Jenkins (Grounding Concepts [2008], 4.8) | |
| A reaction: Now you're talking! This is really interesting conceptual analysis, rather than the sort of stamp-collecting approach to analsis practised by the duller sort of philosopher. But why bother with conceptual examination, when you have senses? |
| 21416 | Philosophers should not offer multiple proofs - suggesting the weakness of each of them [Kant] |
| Full Idea: It is a highly unphilosophic expedient to resort to a number of proofs for one and the same proposition, consoling oneself that the multitude of reasons makes up for the inadequacy of any one of them taken by itself. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 403 Intro XIII) | |
| A reaction: This makes philosophical proofs sound very mathematical in character, whereas I think most reasons for a proposition given in philosophy are more like evidence, which can clearly accumulate in a rational way. Some maths proofs are better than others. |
| 17740 | Instead of correspondence of proposition to fact, look at correspondence of its parts [Jenkins] |
| Full Idea: Instead of considering only a proposition's 'correspondence to the facts', we should also consider the correspondence between parts of the proposition and parts of the world (a 'correspondence-as-congruence' view). | |
| From: Carrie Jenkins (Grounding Concepts [2008], Final - Branching) | |
| A reaction: This is something like Russell's Othello example (1912), except that the parts there, with relations seemed to add up to the whole proposition. For Jenkins, presumably parts might correspond, but the whole proposition fail to. |
| 17884 | Mathematical set theory has many plausible stopping points, such as finitism, and predicativism [Koellner] |
| Full Idea: There are many coherent stopping points in the hierarchy of increasingly strong mathematical systems, starting with strict finitism, and moving up through predicativism to the higher reaches of set theory. | |
| From: Peter Koellner (On the Question of Absolute Undecidability [2006], Intro) |
| 17893 | 'Reflection principles' say the whole truth about sets can't be captured [Koellner] |
| Full Idea: Roughly speaking, 'reflection principles' assert that anything true in V [the set hierarchy] falls short of characterising V in that it is true within some earlier level. | |
| From: Peter Koellner (On the Question of Absolute Undecidability [2006], 2.1) |
| 17894 | We have no argument to show a statement is absolutely undecidable [Koellner] |
| Full Idea: There is at present no solid argument to the effect that a given statement is absolutely undecidable. | |
| From: Peter Koellner (On the Question of Absolute Undecidability [2006], 5.3) |
| 17730 | Combining the concepts of negation and finiteness gives the concept of infinity [Jenkins] |
| Full Idea: We might arrive to the concept of infinity by composing concepts of negation and finiteness. | |
| From: Carrie Jenkins (Grounding Concepts [2008], 5.3) | |
| A reaction: Presumably lots of concepts can be arrived at by negating prior concepts (such as not-wet, not-tall, not-loud, not-straight). So not-infinite is perfectly plausible, and is a far better account than some a priori intuition of pure infinity. Love it. |
| 17890 | There are at least eleven types of large cardinal, of increasing logical strength [Koellner] |
| Full Idea: Some of the standard large cardinals (in order of increasing (logical) strength) are: inaccessible, Mahlo, weakly compact, indescribable, Erdös, measurable, strong, Wodin, supercompact, huge etc. (...and ineffable). | |
| From: Peter Koellner (On the Question of Absolute Undecidability [2006], 1.4) | |
| A reaction: [I don't understand how cardinals can have 'logical strength', but I pass it on anyway] |
| 17887 | PA is consistent as far as we can accept, and we expand axioms to overcome limitations [Koellner] |
| Full Idea: To the extent that we are justified in accepting Peano Arithmetic we are justified in accepting its consistency, and so we know how to expand the axiom system so as to overcome the limitation [of Gödel's Second Theorem]. | |
| From: Peter Koellner (On the Question of Absolute Undecidability [2006], 1.1) | |
| A reaction: Each expansion brings a limitation, but then you can expand again. |
| 17891 | Arithmetical undecidability is always settled at the next stage up [Koellner] |
| Full Idea: The arithmetical instances of undecidability that arise at one stage of the hierarchy are settled at the next. | |
| From: Peter Koellner (On the Question of Absolute Undecidability [2006], 1.4) |
| 17719 | Arithmetic concepts are indispensable because they accurately map the world [Jenkins] |
| Full Idea: The indispensability of arithmetical concepts is evidence that they do in fact accurately represent features of the independent world. | |
| From: Carrie Jenkins (Grounding Concepts [2008], Intro) | |
| A reaction: This seems to me to be by far the best account of the matter. So why is the world so arithmetical? Dunno, mate; ask someone else. |
| 17717 | Senses produce concepts that map the world, and arithmetic is known through these concepts [Jenkins] |
| Full Idea: I propose that arithmetical truths are known through an examination of our own arithmetical concepts; that basic arithmetical concepts map the arithmetical structure of the world; that the map obtains in virtue of our normal sensory apparatus. | |
| From: Carrie Jenkins (Grounding Concepts [2008], Pref) | |
| A reaction: She defends the nice but unusual position that arithmetical knowledge is both a priori and empirical (so that those two notions are not, as usually thought, opposed). I am a big Carrie Jenkins fan. |
| 17724 | It is not easy to show that Hume's Principle is analytic or definitive in the required sense [Jenkins] |
| Full Idea: A problem for the neo-Fregeans is that it has not proved easy to establish that Hume's Principle is analytic or definitive in the required sense. | |
| From: Carrie Jenkins (Grounding Concepts [2008], 4.3) | |
| A reaction: It is also asked how we would know the principle, if it is indeed analytic or definitional (Jenkins p.119). |
| 17727 | We can learn about the world by studying the grounding of our concepts [Jenkins] |
| Full Idea: What concept grounding does for us is ensure that our concepts, like the results of our empirical tests, can be treated as a source of information about the independent world. | |
| From: Carrie Jenkins (Grounding Concepts [2008], 4.4) | |
| A reaction: Presumably we learn our concepts hand-in-hand with experience, so learning our concepts is itself learning about the world. Later checking of concepts and their relations largely confirms what we already knew? |
| 17720 | There's essential, modal, explanatory, conceptual, metaphysical and constitutive dependence [Jenkins, by PG] |
| Full Idea: Dependence comes in essential, modal, explanatory, conceptual, metaphysical and constitutive forms. | |
| From: report of Carrie Jenkins (Grounding Concepts [2008], 1.2) by PG - Db (ideas) | |
| A reaction: You'll have to look up Jenkins for the details. |
| 17728 | The concepts we have to use for categorising are ones which map the real world well [Jenkins] |
| Full Idea: Concepts which are indispensably useful for categorising, understanding, explaining, and predicting our sensory input are likely to be ones which map the structure of that input well. | |
| From: Carrie Jenkins (Grounding Concepts [2008], 4.6) | |
| A reaction: Anti-realists about classification seem to think that we just invent an array of concepts, and then start classifying with them. The truth seems to be that the actual classes of worldly thing have generated our concepts. |
| 21410 | That a concept is not self-contradictory does not make what it represents possible [Kant] |
| Full Idea: That the concept of a thing is possible (not self-contradictory) is not yet sufficient for assuming the possibility of the thing itself (the objective reality of the concept). | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 382 Intro I) | |
| A reaction: I take this to be an inkling of Kripke's a posteriori scientific necessities, which place far greater restrictions on the possibilies of what we seem to have conceived, in addition to the mere need for consistency. |
| 17726 | Examining accurate, justified or grounded concepts brings understanding of the world [Jenkins] |
| Full Idea: Examining accurate concepts can help us acquire true beliefs about the world, examining justified concepts can help us acquire justified beliefs about the world, and examining grounded concepts can help us acquire knowledge of it. | |
| From: Carrie Jenkins (Grounding Concepts [2008], 4.4) | |
| A reaction: This summarises Jenkins's empirical account of concepts, and I love it all to bits. I feel that contemporary philosophy is beginning to produce a coherent naturalistic worldview which can replace religion. Bar the rituals. We can have priests... |
| 17734 | It is not enough that intuition be reliable - we need to know why it is reliable [Jenkins] |
| Full Idea: The mere reliability of intuition is not a satisfactory ground for saying it is a source of knowledge - we need to know why it is reliable to understand whether it can be a source of knowledge. | |
| From: Carrie Jenkins (Grounding Concepts [2008], 6.5) | |
| A reaction: My theory is that intuition is simply believing things for reasons which we have either forgotten, or (more likely) reasons which are too complex or subtle to be articulated. Intuition feels rational, because it is rational. Updated view of mind needed. |
| 17723 | Knowledge is true belief which can be explained just by citing the proposition believed [Jenkins] |
| Full Idea: I propose that knowledge is true belief which can be well explained .....just by citing the proposition believed. | |
| From: Carrie Jenkins (Grounding Concepts [2008], 3.1) | |
| A reaction: I don't find this appealing, and my reservation about Jenkins's book is her reliabilist, externalist epistemology. I would add an internalist coherentist epistemology to her very nice theory. 'I believe there are fairies at the bottom of my garden'? |
| 21421 | Within nature man is unimportant, but as moral person he is above any price [Kant] |
| Full Idea: In the system of nature, man is a being of slight importance ....but man regarded as a person, that is as the subject of a morally practical reason, is exalted above any price. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 434 I.I) | |
| A reaction: See what you've done, John Locke? You've given yet another ground for claiming that humans are angels or demi-gods, exalted far above our animal cousins. |
| 17739 | The physical effect of world on brain explains the concepts we possess [Jenkins] |
| Full Idea: I think the physical effects of the world on the brain explain our possessing the concepts we do. | |
| From: Carrie Jenkins (Grounding Concepts [2008], 8.2) | |
| A reaction: A nice slogan for a thought which strikes me as exactly right. |
| 17718 | Grounded concepts are trustworthy maps of the world [Jenkins] |
| Full Idea: Grounded concepts are like trustworthy on-board maps of the independent world. | |
| From: Carrie Jenkins (Grounding Concepts [2008], Intro) | |
| A reaction: You'll probably need more than one concept for it to qualify as a 'map', but I like this idea a lot. The world, rather than we ourselves, creates our concepts. The opposite of the view of Geach in 'Mental Acts'. |
| 17731 | Verificationism is better if it says meaningfulness needs concepts grounded in the senses [Jenkins] |
| Full Idea: I find an updated verificationism plausible, in which we say something meaningful just in case we employ only concepts whose possession could be justified or disjustified by sensory input. | |
| From: Carrie Jenkins (Grounding Concepts [2008], 5.6) | |
| A reaction: Wow! This is the first time I have ever had the slightest sympathy for verificationism. It saves my favourite problem case - of wild but meaningful speculation, for example about the contents of another universe. A very nice idea. |
| 17732 | Success semantics explains representation in terms of success in action [Jenkins] |
| Full Idea: Success semantics is the attempt to understand mental representation by thinking about the ways in which representing the world can lead to success in action. | |
| From: Carrie Jenkins (Grounding Concepts [2008], 6.3) | |
| A reaction: I take this to be what is also known as 'teleological semantics'. It sounds to me as if this might help to explain success in action, but isn't going to explain the representations that result in the success. |
| 17725 | 'Analytic' can be conceptual, or by meaning, or predicate inclusion, or definition... [Jenkins] |
| Full Idea: 'Analytic' might mean conceptually true, or true in virtue of meaning, or where the predicate is contained in the subject, or for sentences which define something, or where meaning is sufficient for the truth. | |
| From: Carrie Jenkins (Grounding Concepts [2008], 4.3) | |
| A reaction: The second one says meaning grounds the truth, where the last one says meaning entails the truth. |
| 21415 | Duty is impossible without prior moral feeling, conscience, love and self-respect [Kant] |
| Full Idea: Moral feeling, conscience, love of one's neighbour, and respect for oneself (self-esteem). There is no obligation to have these, because they lie at the basis of morality, as subjective conditions of receptiveness to the concept of duty. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 399 Intro XII) | |
| A reaction: A bit of a revelation, this one, because I thought the only precondition for Kantian morality was rationality. Turns out that he agrees with Aristotle (Idea 46) that you can't started in morality if your heart isn't in the right place. |
| 21409 | Moral principles do not involve feelings [Kant] |
| Full Idea: No moral principle is based on any feeling whatsoever. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 376 Pref) |
| 21431 | The love of man is required in order to present the world as a beautiful and perfect moral whole [Kant] |
| Full Idea: Love of man is required by itself, in order to present the world as a beautiful moral whole in its full perfection, even if no account is taken of advantages (of happiness). | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 458 I.II) | |
| A reaction: For me, this illustrates the basic problem with Kant. In the Groundwork he presents morality as arising from pure reason, deriving moral maxims from contradictions, but here we find a totally ungrounded assertion of grand traditional values. |
| 21437 | All morality directs the will to love of others' ends, and respect for others' rights [Kant] |
| Full Idea: All moral relations of rational beings, which involve a principle of the harmony of the will of one with another, can be reduced to love and respect. Love reduces one's will to another's end, and respect to another's right. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 488 II) | |
| A reaction: It all comes out too neat and tidy in Kant. Love doesn't merely focus on another person's 'ends', and respect should be for a lot more than another person's mere 'rights'. They'd have to be natural rights, because some societies restrict rights. |
| 21429 | The duty of love is to makes the ends of others one's own [Kant] |
| Full Idea: The duty of love for one's neighbour can be expressed as the duty to make others' ends my own (provided they are not immoral). | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 449 I.II) | |
| A reaction: An interesting idea. Kant's remarks on love and respect seem distorted, to shoehorn them into his system of end/means and maxims. If I love someone, should I continually enquire what their current ends are? |
| 21411 | A duty of virtue is a duty which is also an end [Kant] |
| Full Idea: Only an end that is also a duty can be called a duty of virtue. ....[385] The necessary ends are one's own perfection, and the happiness of others. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 383 Intro II) | |
| A reaction: So virtues are a subset of duties. I don't think an Aristotelian virtue is anything like a duty. A soldier might do his duty, with no virtue at all. An even a Kantian categorical imperative duty can be formed without right feeling or good character. |
| 21413 | Virtue is strong maxims for duty [Kant] |
| Full Idea: Virtue is the strength of man's maxims in fulfilling his duty. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 394 Intro IX) | |
| A reaction: So virtue is just strong moral commitment. So what are we to make of the lists of distinctive virtues, found in every culture? How do they differ? Only in the areas of duty to which they refer? How do we possess some virtues without others? |
| 21414 | The supreme principle of virtue is to find universal laws for ends [Kant] |
| Full Idea: The supreme principle of the doctrine of virtue is: Act in accordance with a maxim of ends that it can be a universal law for everyone to have. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 395 Intro IX) | |
| A reaction: I'm not sure that any end can be a universal law. I certainly don't expect everyone to study philosophy. I suppose basic human ends, such as kindness and avoidance of suicide, are what he means. He's even more conformist than Aristotle! |
| 21436 | We are obliged to show the social virtues, but at least they make a virtuous disposition fashionable [Kant] |
| Full Idea: Affability, sociability, courtesy, hospitality and gentleness in argument ...are merely the manners one is obliged to show in social intercourse, ...and so they promote a virtuous disposition by at least making virtue fashionable. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 473-4 I.II App) | |
| A reaction: His emphasis on rational duty forces him to diminish virtue, making it sound hypocritical. He needs Aristotle's distinction between the controlled [enkratic] man and the man of true virtue (which is rational and whole-hearted). |
| 21419 | If virtue becomes a habit, that is a loss of the freedom needed for adopting maxims [Kant] |
| Full Idea: If the practice of virtue were to become a habit the subject would suffer loss to that freedom in adopting his maxims which distinguishes an action done from duty. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 409 Intro XVI) | |
| A reaction: Looks like a misunderstanding of Aristotle, who always promotes the role of 'phronesis' [practical reason], and never advocates unthinking virtuous habits. I think Aristotle would ask how you select your maxim, if you lack the virtues. |
| 21417 | How do we distinguish a mean? The extremes can involve quite different maxims [Kant] |
| Full Idea: Who will specify for me this mean between the two extremes? What distinguishes avarice (as a vice) from thrift (as a virtue) is not that avarice carries thift too far but that avarice has an entirely different principle (maxim). | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 404n Intro XIII) | |
| A reaction: He says one concerns enjoyment of possessions, and the other their mere possession. Similarly, reckless courage may aim at glory, while cowardice aims at survival. Aristotle is looking at circumstances, Kant at mental states. |
| 21420 | If virtue is the mean between vices, then virtue is just the vanishing of vice [Kant] |
| Full Idea: If the mean between prodigality and avarice is supposed to be one of degree, then one vice would pass over into the opposite vice only through the virtue. So virtue would simply be a diminished, or rather a vanishing vice. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 432 I.I) | |
| A reaction: Interesting, but not convincing. Doesn't the thought equally show that vice is a vanishing virtue? Aristotle gives the example of the quantity of food we eat, which obviously passes from starvation to appropriate diet to gluttony. |
| 21418 | There is one principle of virtues; the virtues are distinguished by their objects [Kant] |
| Full Idea: To think of several virtues (as one unavoidably does) is nothing other than to think of the various moral objects to which the will is led by the one principle of virtue. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 406 Intro XIII) | |
| A reaction: So Kant commits to the Greek ideal of the unity of virtue - but not for Greek reasons. The unity of duty is what concerns Kant. |
| 21425 | We can love without respect, and show respect without love [Kant] |
| Full Idea: One can love one's neighbour though he might deserve but little respect, and can show him the respect necessary for every man regardless of the fact that he would hardly be judged worthy of love. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 448 I.II) | |
| A reaction: Not sure about this. Respect seems much clearer than love. You can train yourself and others to show respect, but you can't switch on love. Personally, I don't love strangers, but I try hard to respect them. |
| 21427 | Respect is limiting our self-esteem by attending to the human dignity of other persons [Kant] |
| Full Idea: Respect ...is to be understood as the maxim of limiting our self-esteem by the dignity of humanity in another person. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 449 I.II) | |
| A reaction: I can't see any direct connection between my own self-esteem and my respect for others, though in practice great vanity makes us neglect others. I also don't find the concept of 'dignity' very helpful. I think we should respect plants. |
| 21430 | Disrespect is using a person as a mere means to my own ends [Kant] |
| Full Idea: The duty of respect for my neighbour is contained in the maxim not to degrade any other man to a mere means to my ends (not to demand that another throw himself away in order to slave for my end). | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 449 I.II) | |
| A reaction: A weirdly narrow concept of respect. Is enslavement the only way to show disrespect? What about sneering at people, or ignoring them, or prejudicially depriving them of some benefit? |
| 21428 | Respect is purely negative (of not exalting oneself over others), and is thus a duty of Right [Kant] |
| Full Idea: A duty of free respect towards others is only a negative one (of not exalting oneself above others) and is thus analogous to the duty of Right not to encroach upon what belongs to anyone. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 449 I.II) | |
| A reaction: Not good enough. He seems to think belongings are the main issue. By referring to one's own modesty, he has no way to indicate equality of respect (among races, ages, genders, religions, animals etc). Being humble does not entail being respectful. |
| 21426 | Love urges us to get closer to people, but respect to keep our distance [Kant] |
| Full Idea: The principle of mutual love admonishes men constantly to come closer to one another; that of the respect they owe one another, to keep themselves at a distance from one another. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 449 I.II) | |
| A reaction: It might be a situation where it is right to invoke the Golden Rule. Do we want others to be close to us all the time? Probably not. Respect wins, and love loses! Kant's makes a nice distinction. Respect is a virtue, and love is not. |
| 21434 | We must respect the humanity even in a vicious criminal [Kant] |
| Full Idea: I cannot deny all respect to even a vicious man as a man; I cannot withdraw at least the respect that belongs to him in his quality as a man, even though by his deeds he makes himself unworthy of it. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 463 I.II) | |
| A reaction: The obvious way to find some respect for a vicious criminal is to ask how they got that way. Their state is almost certainly self-destructive, and not what they would ever have wished for. Would they choose eternal recurrence? |
| 21412 | Humans are distinguished from animals by their capacity to set themselves any sort of end [Kant] |
| Full Idea: The capacity to set oneself an end - any end whatsoever - is what characterises humanity (as distinguished from animality). | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 392 Intro VIII) | |
| A reaction: This appears to exclude animals which hunt, or build nests - but we have now hugely closed the gap between humans and other animals. I like this, because it chimes in with Sandel's Idea 21045. |
| 21435 | Man is both social, and unsociable [Kant] |
| Full Idea: Man is a being meant for society (though he is also an unsociable one). | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 471 I.II) | |
| A reaction: A striking contrast with Aristotle in Idea 5133. It is the difference between the communitarian and the liberal views of society. The latter values privacy and good fences. |
| 21433 | Violation of rights deserves punishment, which is vengeance, rather than restitution [Kant] |
| Full Idea: Every deed that violates a man's right deserves punishment, the function of which is to avenge a crime on the one who committed it (not merely to make good the harm done). ...but no punishment may be inflicted out of hatred. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 460-1 I.II) | |
| A reaction: A fairly hideous idea, confirming the image of Kant as someone who coldly perfoms ruthless duties. I don't think Kant ever offers any clarity for the concepts of 'deserving' or of 'avenging'. What is the appropriate vengeance for theft? |
| 21423 | Men can only have duties to those who qualify as persons [Kant] |
| Full Idea: Man has duties only to men, ...since his duty to any other subject is moral constraint by that's subject's will. Hence the constraining (binding) subject must first be a person. Man can therefore have no duty to any beings other than men. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 442 I.I) | |
| A reaction: This is good for illuminating why I am not a Kantian. It is not just that animals are ruled out - it is that whether you show respect depends on whether the recipient passes some test or other. Humans with brain damage may fail the test. |
| 21424 | Cruelty to animals is bad because it dulls our empathy for pain in humans [Kant] |
| Full Idea: Cruel treatment of animals is intimately opposed to man's duty to himself; ...for it dulls his shared feeling of their pain and so weakens and gradually uproots a natural predisposition that is very serviceable to morality in relations with other men. | |
| From: Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 443 I.I) | |
| A reaction: This idea is quite shocking. Kant's rough contemporary Bentham was far more enlightened. If we could be certain that our feelings of empathy for pain were not dulled by cruelty to animals, then it would be fine. |
