In contrast the solution of the other antinomies is that both thesis and antithesis are true, and that is possible because they are concerned with different things. The third antinomy arises from the difficulty of applying the category of causation to the world as a whole. The assumption underlying the thesis is not, as is sometimes asserted, merely that the notion of infinity in itself implies a contradiction, but that a determinate result must have a determinate cause. If we think of what actually exists now as having been caused by what has preceded it, we must think of that which has had a determinate result being itself determinate. It is the familiar argument for a first cause. In causation we seem to be relating one event to another event, and are really only putting the question of origination further back. Yet, if we say that therefore we must suppose an absolute origination of change, a beginning of the series, we have to answer the question, How is it possible to think of the originating number of the series? For to think that something can arise from nothing is to contradict the principle of causation.

Kant's analysis of these proofs seems negative. Its real purport is to insist that religion cannot be dissociated from moral experience, that the knowledge of God, which is the concern of religion, is not got by intellectual speculation, but in the moral life. When he said that he had limited reason to make room for faith, he did not mean that men could not prove the existence of God, but might believe in it if they pleased. He meant that God is implied and known above all in moral action. His criticism of these classical proofs is thus the beginning of that revivified philosophy of religion whose chief representatives have been Schleiermacher and Ritschl.

But when we consider our moral judgments we seem to be in a different world, for there are some actions which we think we or others ought to have done or ought not to have done, and this obligation has nothing to do with our likes and dislikes. If we look back upon a past action of our own, we may see why we did it, understand how the temptation to it appealed with peculiar strength to something in our nature, yet nevertheless we may say that we ought not to have done it, and with that judgment goes the conviction that we need not have done it. The conception of "what ought to be" is on a different plane from the conception of "what is," and assumes a different kind of causality. It assumes that, when we are done with our analysis of character, of a man's likes and dislikes and the effect of circumstances upon them, we can still assume that it is in his power to do what he ought and to abstain from doing what he ought not. We praise the first and blame the second, whether in ourselves or others, just because we assume, over and above inclination and disinclination, a possibility of acting or not acting as duty demands.

Kant's account of duty is determined by the sharp separation which he makes of man as moral agent and man regarded "from the point of view of anthropology." The commands of duty must be derived solely from the nature of man as a moral agent. If they were the consequence of man's empirical nature or his surroundings, they would have no claim to override his promptings of inclination or pleasure. He describes these commands as categorical, and the principle of morality as a categorical imperative. The meaning of this phrase lies in its opposition to hypothetical. Many commands and principles are, Kant says, hypothetical. They assume that men desire certain ends, happiness or health or success, and the actions they advise are advised as means to such ends. The law of morality is quite different from such prudential maxims. It does not say, "If you want to be happy or to save your soul, then act thus and thus." Its commands are absolute, for they appeal to man simply as a rational being. They must therefore be derived solely from a consideration of man's rationality. It is difficult at first sight to see how any commands can be deduced from a consideration so abstract. How, we might say, can man's rationality be known and recognised except in the content of what he does and thinks?

Such in outline is Kant's account of morality. A discussion of some of the difficulties which a consideration of it suggests may help to make its purport more clear. Kant holds that the principles of right action can be deduced directly from the imperative he has formulated, and need take therefore no account of historical circumstance. Now, it is easy to show that, when we do an action which we know to be wrong, we are making an exception in our own favour. We cannot universalise the maxim of our own conduct. When we do what we know to be wrong, we recognise what is right. We say, "This is how any one ought to act in these circumstances, but I am not going to do it." We must learn to look upon ourselves as we should look upon and judge any other moral agent. If, when taxed with wrongdoing, we reply, "I wanted to do it," or "That is the kind of person I am," or "That is the way I am made," we are abandoning the moral position, and the answer is, "Whether you wanted it or not, you ought not to have done it," or, "Well, you ought to become different." But this does not help us when, looking at actions from a moral standpoint, it is difficult to say what ought to be done. Kant tries to show that wrong action, if universalised, is always contradictory. He takes the instance of telling a lie. If that were universal no one would believe any one else, and there would be no point in telling a lie. Lying is essentially parasitical. But this does not help us in the familiar problem in casuistry, whether it is allowable to tell a lie to save life. For here we have a conflict between two maxims, both of which can be universalised. We cannot regard such a situation as simply involving a question of telling the truth or of saving life. We must consider the circumstances of the case. This is even more evident if we apply Kant's rule to the question of whether celibacy is ever justified. If celibacy were universal, there would soon be nobody to be celibate, but it does not therefore follow that some people under certain circumstances ought not to be celibate. The question cannot be answered without reference to circumstances. The moral of this is that the categorical imperative does not enable us to act without individual moral judgment in individual cases. Further, in one of the instances which Kant gives he admits that there are certain ways of action which might be universalised, but which he nevertheless holds to be wrong. He instances the duty of being industrious. A society could quite well be imagined in which every one was lazy, but he says, "It cannot be willed." The ultimate appeal here is to what the moral reason wills. That means that we must admit that the moral reason or moral judgment has a content not derivable simply from the conception of the moral law; that there are certain kinds of life, certain kinds of action, which we judge to be good, and others which we judge to be bad. But, if this is so, we must give up the sharp separation Kant makes between the moral law and nature, and allow that things in nature can have a moral value. It may still be true that they only have moral value through their relation to a good will, and have no moral significance apart from such a relation.

The difficulties created by Kant's sharp separation of the moral and the phenomenal worlds are equally apparent in his discussion of motives. He conceives the individual as phenomenal, to be determined solely by pleasure and pain. The power of the moral law is manifest, therefore, when its commands run counter to inclination, and the motive of respect for the moral law conquers inclination. It is true to say that a man's likes and dislikes in themselves are not to the point when we are asking what he ought to do, but Kant sometimes speaks as though there could be no moral value in an action which did not go against inclination. This is perilously near that morbid theory of conscience which assumes that the fact that an action would be very disagreeable to the agent is itself proof that the proposal to perform it is the voice of conscience. Here again we have to say that the fact that inclinations viewed merely as inclinations have no moral value, does not show that, relatively to the good will, one may not be better than another. There is nothing to be proud of in the fact that we dislike doing our duty.

These assumptions are, according to Kant, quite different from the principles of the understanding. For the latter are grounds of the possibility of experience. We cannot deny them without making experience unmeaning. This cannot be said of the former. It obviously cannot be essential to experience that the multiplicity of the laws of nature should be reducible to unity, for such unity has never been discovered. Experience has been quite possible without it. This distinction between two kinds of principles Kant expresses by calling those with which we are now concerned regulative. The purpose they serve is the regulation and improvement of knowledge. They do not, like the principles of the understanding, prescribe to nature. We assume in them that nature is, in Kant's words, purposive to the understanding--that is, we first think out what order of nature would be intelligible, and then look to see whether we cannot discover in nature such an order. This assumption does not prove that there is any such order, but in science we act as if it were there to be found out.

This suggestion of Kant's has been elaborated in many modern writers on philosophy, who have pointed out how much scientific method is governed by the notion of the most easily intelligible theory, and they have argued that science assumes, for the convenience of method, principles which it never completely proves. These principles are called sometimes methodological assumptions, sometimes postulates. The difference between such modern writers and Kant is that the former think that all a priori principles are of this nature, and that the principle of causation, for example, is itself only a postulate.

The faculty of judgment, then, according to Kant, assumes for regulative purposes that nature is purposive to our understanding. What does this last phrase mean? We are often concerned to know the relation of things to our purposes. It has been pointed out that very many of our empirical concepts represent rather our practical interest in things than our desire to understand them as they are. Kant's phrase implies that, apart from any such relation to particular purposes, there is a more general purpose of mere intelligibility, which some objects obviously serve more than others.

Beautiful objects, then, are "purposive to the understanding," inasmuch as their form stimulates in the most harmonious degree the two faculties of intelligence, and in art we find proof that there is a principle of general intelligibility, which may guide the work of the scientist. The purpose of the scientist is quite different from that of the artist, but if he is to reduce his facts to order and intelligibility he must be guided by a principle which is seen in its pure form in the artist.

Kant's solution of this antinomy is that both mechanism and teleology are only regulative principles. They tell us nothing of the ultimate nature of reality, except that we can explain much of it by regarding it as if it were a machine, and much by regarding it as if it were the field of purposive agency. Reality must be consistent with both these facts, but more we cannot say. The moral is that we should continue to treat them as regulative principles, and push each principle of explanation as far as it will go.

Kant is here, as usual, the enemy alike of scientific and of theological dogmatism. He will not allow any limit to be set to the work of scientific investigation, and yet will not allow a principle of scientific method to be converted from an explanation of perceived facts into a theory of the universe.

Besides mediating between the conflicting claims of mechanism and teleology, Kant also modifies the notion of teleology. When we think of reality as purposive, we do not necessarily think of it as having a definite purpose, as being subordinate, for example, to the well-being of man. The principle of purposiveness arises properly, he holds, from the contemplation of living things, from the perception of the difference between an organism and a machine. An organism is purposive in the sense in which a work of art is. In applying the principle we are trying to understand reality as though the relation of all the different things in it were like the relation of the parts of an organism or a picture. But this principle, like the principle of mechanism, does not carry us further than the facts we have examined, for an organism or a work of art can only be understood by study of the individual relations of all its parts. We can never know the universe as an organism, for we can never know all its parts. We can understand and put together more and more of them, but we never come to the end.
