The Critique of Practical Reason by Immanuel Kant (the false prince series txt) 📕

>The physical law being a law to which the objects of sensible intuition, as such, are subject, must have a schema corresponding to it-that is, a general procedure of the imagination (by which it exhibits a priori to the senses the pure concept of the understanding which the law determines). But the law of freedom (that is, of a causality not subject to sensible conditions), and consequently the concept of the unconditionally good, cannot have any intuition, nor consequently any schema supplied to it for the purpose of its application in concreto. Consequently the moral law has no faculty but the understanding to aid its application to physical objects (not the imagination); and the understanding for the purposes of the judgement can provide for an idea of the reason, not a schema of the sensibility, but a law, though only as to its form as law; such a law, however, as can be exhibited in concreto in objects of the senses, and therefore a law of nature. We can therefore call this law the type of the moral law.

The rule of the judgement according to laws of pure practical reason is this: ask yourself whether, if the action you propose were to take place by a law of the system of nature of which you were yourself a part, you could regard it as possible by your own will. Everyone does, in fact, decide by this rule whether actions are morally good or evil. Thus, people say: “If everyone permitted himself to deceive, when he thought it to his advantage; or thought himself justified in shortening his life as soon as he was thoroughly weary of it; or looked with perfect indifference on the necessity of others; and if you belonged to such an order of things, would you do so with the assent of your own will?” Now everyone knows well that if he secretly allows himself to deceive, it does not follow that everyone else does so; or if, unobserved, he is destitute of compassion, others would not necessarily be so to him; hence, this comparison of the maxim of his actions with a universal law of nature is not the determining principle of his will. Such a law is, nevertheless, a type of the estimation of the maxim on moral principles. If the maxim of the action is not such as to stand the test of the form of a universal law of nature, then it is morally impossible. This is the judgement even of common sense; for its ordinary judgements, even those of experience, are always based on the law of nature. It has it therefore always at hand, only that in cases where causality from freedom is to be criticised, it makes that law of nature only the type of a law of freedom, because, without something which it could use as an example in a case of experience, it could not give the law of a pure practical reason its proper use in practice.

It is therefore allowable to use the system of the world of sense as the type of a supersensible system of things, provided I do not transfer to the latter the intuitions, and what depends on them, but merely apply to it the form of law in general (the notion of which occurs even in the commonest use of reason, but cannot be definitely known a priori for any other purpose than the pure practical use of reason); for laws, as such, are so far identical, no matter from what they derive their determining principles.

{BOOK_1|CHAPTER_2 ^paragraph 50}

Further, since of all the supersensible absolutely nothing [is known] except freedom (through the moral law), and this only so far as it is inseparably implied in that law, and moreover all supersensible objects to which reason might lead us, following the guidance of that law, have still no reality for us, except for the purpose of that law, and for the use of mere practical reason; and as reason is authorized and even compelled to use physical nature (in its pure form as an object of the understanding) as the type of the judgement; hence, the present remark will serve to guard against reckoning amongst concepts themselves that which belongs only to the typic of concepts. This, namely, as a typic of the judgement, guards against the empiricism of practical reason, which founds the practical notions of good and evil merely on experienced consequences (so-called happiness). No doubt happiness and the infinite advantages which would result from a will determined by selflove, if this will at the same time erected itself into a universal law of nature, may certainly serve as a perfectly suitable type of the morally good, but it is not identical with it. The same typic guards also against the mysticism of practical reason, which turns what served only as a symbol into a schema, that is, proposes to provide for the moral concepts actual intuitions, which, however, are not sensible (intuitions of an invisible Kingdom of God), and thus plunges into the transcendent. What is befitting the use of the moral concepts is only the rationalism of the judgement, which takes from the sensible system of nature only what pure reason can also conceive of itself, that is, conformity to law, and transfers into the supersensible nothing but what can conversely be actually exhibited by actions in the world of sense according to the formal rule of a law of nature.

However, the caution against empiricism of practical reason is much more important; for mysticism is quite reconcilable with the purity and sublimity of the moral law, and, besides, it is not very natural or agreeable to common habits of thought to strain one’s imagination to supersensible intuitions; and hence the danger on this side is not so general. Empiricism, on the contrary, cuts up at the roots the morality of intentions (in which, and not in actions only, consists the high worth that men can and ought to give to themselves), and substitutes for duty something quite different, namely, an empirical interest, with which the inclinations generally are secretly leagued; and empiricism, moreover, being on this account allied with all the inclinations which (no matter what fashion they put on) degrade humanity when they are raised to the dignity of a supreme practical principle; and as these, nevertheless, are so favourable to everyone’s feelings, it is for that reason much more dangerous than mysticism, which can never constitute a lasting condition of any great number of persons.

CHAPTER III. Of the Motives of Pure Practical Reason.

What is essential in the moral worth of actions is that the moral law should directly determine the will. If the determination of the will takes place in conformity indeed to the moral law, but only by means of a feeling, no matter of what kind, which has to be presupposed in order that the law may be sufficient to determine the will, and therefore not for the sake of the law, then the action will possess legality, but not morality. Now, if we understand by motive (elater animi) the subjective ground of determination of the will of a being whose reason does not necessarily conform to the objective law, by virtue of its own nature, then it will follow, first, that not motives can be attributed to the Divine will, and that the motives of the human will (as well as that of every created rational being) can never be anything else than the moral law, and consequently that the objective principle of determination must always and alone be also the subjectively sufficient determining principle of the action, if this is not merely to fulfil the letter of the law, without containing its spirit. *

* We may say of every action that conforms to the law, but is not done for the sake of the law, that it is morally good in the letter, not in the spirit (the intention).

Since, then, for the purpose of giving the moral law influence over the will, we must not seek for any other motives that might enable us to dispense with the motive of the law itself, because that would produce mere hypocrisy, without consistency; and it is even dangerous to allow other motives (for instance, that of interest) even to co-operate along with the moral law; hence nothing is left us but to determine carefully in what way the moral law becomes a motive, and what effect this has upon the faculty of desire. For as to the question how a law can be directly and of itself a determining principle of the will (which is the essence of morality), this is, for human reason, an insoluble problem and identical with the question: how a free will is possible. Therefore what we have to show a priori is not why the moral law in itself supplies a motive, but what effect it, as such, produces (or, more correctly speaking, must produce) on the mind.

{BOOK_1|CHAPTER_3 ^paragraph 5}

The essential point in every determination of the will by the moral law is that being a free will it is determined simply by the moral law, not only without the co-operation of sensible impulses, but even to the rejection of all such, and to the checking of all inclinations so far as they might be opposed to that law. So far, then, the effect of the moral law as a motive is only negative, and this motive can be known a priori to be such. For all inclination and every sensible impulse is founded on feeling, and the negative effect produced on feeling (by the check on the inclinations) is itself feeling; consequently, we can see a priori that the moral law, as a determining principle of the will, must by thwarting all our inclinations produce a feeling which may be called pain; and in this we have the first, perhaps the only, instance in which we are able from a priori considerations to determine the relation of a cognition (in this case of pure practical reason) to the feeling of pleasure or displeasure. All the inclinations together (which can be reduced to a tolerable system, in which case their satisfaction is called happiness) constitute self-regard (solipsismus). This is either the selflove that consists in an excessive fondness for oneself (philautia), or satisfaction with oneself (arrogantia). The former is called particularly selfishness; the latter self-conceit. Pure practical reason only checks selfishness, looking on it as natural and active in us even prior to the moral law, so far as to limit it to the condition of agreement with this law, and then it is called rational selflove. But self-conceit reason strikes down altogether, since all claims to selfesteem which precede agreement with the moral law are vain and unjustifiable, for the certainty of a state of mind that coincides with this law is the first condition of personal worth (as we shall presently show more clearly), and prior to this conformity any pretension to worth is false and unlawful. Now the propensity to selfesteem is one of the inclinations which the moral law checks, inasmuch as that esteem rests only on morality.

Therefore the moral law breaks down self-conceit. But as this law is something positive in itself, namely, the form of an intellectual causality, that is, of freedom, it must be an object of respect; for, by opposing the subjective antagonism of the inclinations, it weakens self-conceit; and since it even breaks down, that is, humiliates, this conceit, it is an object of the highest respect and, consequently, is the foundation of a positive feeling which is not of empirical origin, but is known a priori. Therefore respect for the moral law is a feeling which is produced by an intellectual cause, and this feeling is the only one that we know quite a priori and the necessity of which we can perceive.
