| 3722 | 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) |
| 3738 | 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) |
| 10987 | Three traditional names of rules are 'Simplification', 'Addition' and 'Disjunctive Syllogism' [Read] |
| Full Idea: Three traditional names for rules are 'Simplification' (P from 'P and Q'), 'Addition' ('P or Q' from P), and 'Disjunctive Syllogism' (Q from 'P or Q' and 'not-P'). | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) |
| 11004 | Necessity is provability in S4, and true in all worlds in S5 [Read] |
| Full Idea: In S4 necessity is said to be informal 'provability', and in S5 it is said to be 'true in every possible world'. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.4) | |
| A reaction: It seems that the S4 version is proof-theoretic, and the S5 version is semantic. |
| 11018 | There are fuzzy predicates (and sets), and fuzzy quantifiers and modifiers [Read] |
| Full Idea: In fuzzy logic, besides fuzzy predicates, which define fuzzy sets, there are also fuzzy quantifiers (such as 'most' and 'few') and fuzzy modifiers (such as 'usually'). | |
| From: Stephen Read (Thinking About Logic [1995], Ch.7) |
| 11011 | Same say there are positive, negative and neuter free logics [Read] |
| Full Idea: It is normal to classify free logics into three sorts; positive free logics (some propositions with empty terms are true), negative free logics (they are false), and neuter free logics (they lack truth-value), though I find this unhelpful and superficial. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.5) |
| 11020 | Realisms like the full Comprehension Principle, that all good concepts determine sets [Read] |
| Full Idea: Hard-headed realism tends to embrace the full Comprehension Principle, that every well-defined concept determines a set. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.8) | |
| A reaction: This sort of thing gets you into trouble with Russell's paradox (though that is presumably meant to be excluded somehow by 'well-defined'). There are lots of diluted Comprehension Principles. |
| 10986 | Not all validity is captured in first-order logic [Read] |
| Full Idea: We must recognise that first-order classical logic is inadequate to describe all valid consequences, that is, all cases in which it is impossible for the premisses to be true and the conclusion false. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) | |
| A reaction: This is despite the fact that first-order logic is 'complete', in the sense that its own truths are all provable. |
| 10972 | The non-emptiness of the domain is characteristic of classical logic [Read] |
| Full Idea: The non-emptiness of the domain is characteristic of classical logic. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) |
| 11024 | Semantics must precede proof in higher-order logics, since they are incomplete [Read] |
| Full Idea: For the realist, study of semantic structures comes before study of proofs. In higher-order logic is has to, for the logics are incomplete. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.9) | |
| A reaction: This seems to be an important general observation about any incomplete system, such as Peano arithmetic. You may dream the old rationalist dream of starting from the beginning and proving everything, but you can't. Start with truth and meaning. |
| 10985 | We should exclude second-order logic, precisely because it captures arithmetic [Read] |
| Full Idea: Those who believe mathematics goes beyond logic use that fact to argue that classical logic is right to exclude second-order logic. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) |
| 10970 | A theory of logical consequence is a conceptual analysis, and a set of validity techniques [Read] |
| Full Idea: A theory of logical consequence, while requiring a conceptual analysis of consequence, also searches for a set of techniques to determine the validity of particular arguments. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) |
| 10984 | Logical consequence isn't just a matter of form; it depends on connections like round-square [Read] |
| Full Idea: If classical logic insists that logical consequence is just a matter of the form, we fail to include as valid consequences those inferences whose correctness depends on the connections between non-logical terms (such as 'round' and 'square'). | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) | |
| A reaction: He suggests that an inference such as 'round, so not square' should be labelled as 'materially valid'. |
| 10973 | A theory is logically closed, which means infinite premisses [Read] |
| Full Idea: A 'theory' is any logically closed set of propositions, ..and since any proposition has infinitely many consequences, including all the logical truths, so that theories have infinitely many premisses. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) | |
| A reaction: Read is introducing this as the essential preliminary to an account of the Compactness Theorem, which relates these infinite premisses to the finite. |
| 11007 | Quantifiers are second-order predicates [Read] |
| Full Idea: Quantifiers are second-order predicates. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.5) | |
| A reaction: [He calls this 'Frege's insight'] They seem to be second-order in Tarski's sense, that they are part of a metalanguage about the sentence, rather than being a part of the sentence. |
| 10978 | In second-order logic the higher-order variables range over all the properties of the objects [Read] |
| Full Idea: The defining factor of second-order logic is that, while the domain of its individual variables may be arbitrary, the range of the first-order variables is all the properties of the objects in its domain (or, thinking extensionally, of the sets objects). | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) | |
| A reaction: The key point is that the domain is 'all' of the properties. How many properties does an object have. You need to decide whether you believe in sparse or abundant properties (I vote for very sparse indeed). |
| 10971 | A logical truth is the conclusion of a valid inference with no premisses [Read] |
| Full Idea: Logical truth is a degenerate, or extreme, case of consequence. A logical truth is the conclusion of a valid inference with no premisses, or a proposition in the premisses of an argument which is unnecessary or may be suppressed. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) |
| 10988 | Any first-order theory of sets is inadequate [Read] |
| Full Idea: Any first-order theory of sets is inadequate because of the Löwenheim-Skolem-Tarski property, and the consequent Skolem paradox. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) | |
| A reaction: The limitation is in giving an account of infinities. |
| 10974 | Compactness is when any consequence of infinite propositions is the consequence of a finite subset [Read] |
| Full Idea: Classical logical consequence is compact, which means that any consequence of an infinite set of propositions (such as a theory) is a consequence of some finite subset of them. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) |
| 10975 | Compactness does not deny that an inference can have infinitely many premisses [Read] |
| Full Idea: Compactness does not deny that an inference can have infinitely many premisses. It can; but classically, it is valid if and only if the conclusion follows from a finite subset of them. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) |
| 10977 | Compactness blocks the proof of 'for every n, A(n)' (as the proof would be infinite) [Read] |
| Full Idea: Compact consequence undergenerates - there are intuitively valid consequences which it marks as invalid, such as the ω-rule, that if A holds of the natural numbers, then 'for every n, A(n)', but the proof of that would be infinite, for each number. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) |
| 10976 | Compactness makes consequence manageable, but restricts expressive power [Read] |
| Full Idea: Compactness is a virtue - it makes the consequence relation more manageable; but it is also a limitation - it limits the expressive power of the logic. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) | |
| A reaction: The major limitation is that wholly infinite proofs are not permitted, as in Idea 10977. |
| 11014 | Self-reference paradoxes seem to arise only when falsity is involved [Read] |
| Full Idea: It cannot be self-reference alone that is at fault. Rather, what seems to cause the problems in the paradoxes is the combination of self-reference with falsity. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.6) |
| 11025 | Infinite cuts and successors seems to suggest an actual infinity there waiting for us [Read] |
| Full Idea: Every potential infinity seems to suggest an actual infinity - e.g. generating successors suggests they are really all there already; cutting the line suggests that the point where the cut is made is already in place. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.8) | |
| A reaction: Finding a new gambit in chess suggests it was there waiting for us, but we obviously invented chess. Daft. |
| 10979 | Although second-order arithmetic is incomplete, it can fully model normal arithmetic [Read] |
| Full Idea: Second-order arithmetic is categorical - indeed, there is a single formula of second-order logic whose only model is the standard model ω, consisting of just the natural numbers, with all of arithmetic following. It is nevertheless incomplete. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) | |
| A reaction: This is the main reason why second-order logic has a big fan club, despite the logic being incomplete (as well as the arithmetic). |
| 10980 | Second-order arithmetic covers all properties, ensuring categoricity [Read] |
| Full Idea: Second-order arithmetic can rule out the non-standard models (with non-standard numbers). Its induction axiom crucially refers to 'any' property, which gives the needed categoricity for the models. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) |
| 10997 | Von Neumann numbers are helpful, but don't correctly describe numbers [Read] |
| Full Idea: The Von Neumann numbers have a structural isomorphism to the natural numbers - each number is the set of all its predecessors, so 2 is the set of 0 and 1. This helps proofs, but is unacceptable. 2 is not a set with two members, or a member of 3. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.4) |
| 11016 | Would a language without vagueness be usable at all? [Read] |
| Full Idea: We must ask whether a language without vagueness would be usable at all. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.7) | |
| A reaction: Popper makes a similar remark somewhere, with which I heartily agreed. This is the idea of 'spreading the word' over the world, which seems the right way of understanding it. |
| 11013 | Identities and the Indiscernibility of Identicals don't work with supervaluations [Read] |
| Full Idea: In supervaluations, the Law of Identity has no value for empty names, and remains so if extended. The Indiscernibility of Identicals also fails if extending it for non-denoting terms, where Fa comes out true and Fb false. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.5) |
| 11012 | A 'supervaluation' gives a proposition consistent truth-value for classical assignments [Read] |
| Full Idea: A 'supervaluation' says a proposition is true if it is true in all classical extensions of the original partial valuation. Thus 'A or not-A' has no valuation for an empty name, but if 'extended' to make A true or not-true, not-A always has opposite value. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.5) |
| 11019 | Supervaluations say there is a cut-off somewhere, but at no particular place [Read] |
| Full Idea: The supervaluation approach to vagueness is to construe vague predicates not as ones with fuzzy borderlines and no cut-off, but as having a cut-off somewhere, but in no particular place. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.7) | |
| A reaction: Presumably you narrow down the gap by supervaluation, then split the difference to get a definite value. |
| 10995 | A haecceity is a set of individual properties, essential to each thing [Read] |
| Full Idea: The haecceitist (a neologism coined by Duns Scotus, pronounced 'hex-ee-it-ist', meaning literally 'thisness') believes that each thing has an individual essence, a set of properties which are essential to it. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.4) | |
| A reaction: This seems to be a difference of opinion over whether a haecceity is a set of essential properties, or a bare particular. The key point is that it is unique to each entity. |
| 11001 | Equating necessity with truth in every possible world is the S5 conception of necessity [Read] |
| Full Idea: The equation of 'necessity' with 'true in every possible world' is known as the S5 conception, corresponding to the strongest of C.I.Lewis's five modal systems. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.4) | |
| A reaction: Are the worlds naturally, or metaphysically, or logically possible? |
| 10989 | The standard view of conditionals is that they are truth-functional [Read] |
| Full Idea: The standard view of conditionals is that they are truth-functional, that is, that their truth-values are determined by the truth-values of their constituents. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.3) |
| 10992 | The point of conditionals is to show that one will accept modus ponens [Read] |
| Full Idea: The point of conditionals is to show that one will accept modus ponens. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.3) | |
| A reaction: [He attributes this idea to Frank Jackson] This makes the point, against Grice, that the implication of conditionals is not conversational but a matter of logical convention. See Idea 21396 for a very different view. |
| 11017 | Some people even claim that conditionals do not express propositions [Read] |
| Full Idea: Some people even claim that conditionals do not express propositions. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.7) | |
| A reaction: See Idea 14283, where this appears to have been 'proved' by Lewis, and is not just a view held by some people. |
| 10983 | Knowledge of possible worlds is not causal, but is an ontology entailed by semantics [Read] |
| Full Idea: The modal Platonist denies that knowledge always depends on a causal relation. The reality of possible worlds is an ontological requirement, to secure the truth-values of modal propositions. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) | |
| A reaction: [Reply to Idea 10982] This seems to be a case of deriving your metaphyics from your semantics, of which David Lewis seems to be guilty, and which strikes me as misguided. |
| 10982 | How can modal Platonists know the truth of a modal proposition? [Read] |
| Full Idea: If modal Platonism was true, how could we ever know the truth of a modal proposition? | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) | |
| A reaction: I take this to be very important. Our knowledge of modal truths must depend on our knowledge of the actual world. The best answer seems to involve reference to the 'powers' of the actual world. A reply is in Idea 10983. |
| 10996 | Actualism is reductionist (to parts of actuality), or moderate realist (accepting real abstractions) [Read] |
| Full Idea: There are two main forms of actualism: reductionism, which seeks to construct possible worlds out of some more mundane material; and moderate realism, in which the actual concrete world is contrasted with abstract, but none the less real, possible worlds. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.4) | |
| A reaction: I am a reductionist, as I do not take abstractions to be 'real' (precisely because they have been 'abstracted' from the things that are real). I think I will call myself a 'scientific modalist' - we build worlds from possibilities, discovered by science. |
| 10981 | A possible world is a determination of the truth-values of all propositions of a domain [Read] |
| Full Idea: A possible world is a complete determination of the truth-values of all propositions over a certain domain. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.2) | |
| A reaction: Even if the domain is very small? Even if the world fitted the logic nicely, but was naturally impossible? |
| 11000 | If worlds are concrete, objects can't be present in more than one, and can only have counterparts [Read] |
| Full Idea: If each possible world constitutes a concrete reality, then no object can be present in more than one world - objects may have 'counterparts', but cannot be identical with them. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.4) | |
| A reaction: This explains clearly why in Lewis's modal realist scheme he needs counterparts instead of rigid designation. Sounds like a slippery slope. If you say 'Humphrey might have won the election', who are you talking about? |
| 3726 | 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) |
| 10998 | The mind abstracts ways things might be, which are nonetheless real [Read] |
| Full Idea: Ways things might be are real, but only when abstracted from the actual way things are. They are brought out and distinguished by the mind, by abstraction, but are not dependent on mind for their existence. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.4) | |
| A reaction: To me this just flatly contradicts itself. The idea that the mind can 'bring something out' by its operations, with the result being then accepted as part of reality is nonsense on stilts. What is real is the powers that make the possibilities. |
| 3739 | 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) |
| 3741 | 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) |
| 3740 | 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) |
| 5296 | 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!" |
| 24011 | 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. |
| 11005 | Negative existentials with compositionality make the whole sentence meaningless [Read] |
| Full Idea: A problem with compositionality is negative existential propositions. If some of the terms of the proposition are empty, and don't refer, then compositionality implies that the whole will lack meaning too. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.5) | |
| A reaction: I don't agree. I don't see why compositionality implies holism about sentence-meaning. If I say 'that circular square is a psychopath', you understand the predication, despite being puzzled by the singular term. |
| 10966 | A proposition objectifies what a sentence says, as indicative, with secure references [Read] |
| Full Idea: A proposition makes an object out of what is said or expressed by the utterance of a certain sort of sentence, namely, one in the indicative mood which makes sense and doesn't fail in its references. It can then be an object of thought and belief. | |
| From: Stephen Read (Thinking About Logic [1995], Ch.1) | |
| A reaction: Nice, but two objections: I take it to be crucial to propositions that they eliminate ambiguities, and I take it that animals are capable of forming propositions. Read seems to regard them as fictions, but I take them to be brain events. |
| 5074 | 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. |
| 8024 | 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. |
| 22390 | 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. |
| 9750 | 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. |
| 20160 | 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). |
| 9749 | 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! |
| 7671 | 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. |
| 3717 | 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. |
| 3720 | 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. |
| 3712 | 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. |
| 3725 | 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. |
| 3733 | 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) |
| 3736 | 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) |
| 3544 | 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 |
| 7903 | The six perfections are giving, morality, patience, vigour, meditation, and wisdom [Nagarjuna] |
| Full Idea: The six perfections are of giving, morality, patience, vigour, meditation, and wisdom. | |
| From: Nagarjuna (Mahaprajnaparamitashastra [c.120], 88) | |
| A reaction: What is 'morality', if giving is not part of it? I like patience and vigour being two of the virtues, which immediately implies an Aristotelian mean (which is always what is 'appropriate'). |
| 7674 | 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. |
| 21029 | 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. |
| 7105 | 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. |
| 7625 | 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. |
| 4024 | 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. |
| 3710 | 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). |
| 20715 | 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. |
| 3737 | 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) |
| 3715 | 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) |
| 3718 | 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) |
| 3735 | 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) |
| 3714 | 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) |
| 5295 | 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. |
| 3724 | 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) |
| 3723 | 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) |
| 6695 | 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. |
| 8028 | 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? |
| 8026 | 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? |
| 3719 | 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) |
| 3716 | 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) |
| 4413 | 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. |
| 15673 | 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? |
| 8068 | 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. |
| 8025 | 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? |
| 3762 | 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 |
| 8027 | 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'. |
| 3728 | 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) |
| 22008 | 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? |
| 22009 | 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. |
| 3727 | 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) |
| 3731 | 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) |
| 22050 | 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. |
| 6694 | 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? |
| 3711 | 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) |
| 3713 | 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) |
| 4345 | 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? |
| 4251 | 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. |
| 16004 | 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] |
| 3729 | 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) |
| 4344 | 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. |
| 3732 | 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) |
| 7670 | 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. |
| 7591 | 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. |
| 7673 | 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. |
| 3730 | 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'. |
| 3721 | 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) |
| 8046 | 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? |
| 20714 | 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? |
