THE CRITIQUE OF JUDGMENT. Immanuel Kant

that we can claim for it objective validity. In the language of the Critique of Pure Reason, the Idea of God furnishes a regulative, not a constitutive principle of Reason; or as he prefers to put it in the present work, it is valid only for the reflective, not for the determinant Judgement. We are not justified, Kant maintains, in asserting dogmatically that God exists; there is only permitted to us the limited formula “We cannot otherwise conceive the purposiveness which must lie at the basis of our cognition of the internal possibility of many natural things, than by representing it and the world in general as produced by an intelligent cause, i.e. a God” (p. 312).

      We ask then, whence arises this impossibility of objective statement? It is in the true Kantian spirit to assert that no synthetical proposition can be made with reference to what lies above and behind the world of sense; but there is a difficulty in carrying out this principle into details. Kant’s refusal to infer a designing Hand behind the apparent order of nature is based, he tells us, on the fact that the concept of a “natural purpose” is one that cannot be justified to the speculative Reason. For all we know it may only indicate our way of looking at things, and may point to no corresponding objective reality. That we are forced by the limited nature of our faculties to view nature as working towards ends, as purposive, does not prove that it is really so. We cannot justify such pretended insight into what is behind the veil.

      It is to be observed, however, that precisely similar arguments might be urged against our affirmation of purpose, design, will, as the spring of the actions of other human beings.3 For let us consider why it is that, mind being assumed as the basis of our own individual consciousness, we go on to attribute minds of like character to other men. We see that the external behaviour of other men is similar to our own, and that the most reasonable way of accounting for such behaviour is to suppose that they have minds like ourselves, that they are possessed of an active and spontaneously energising faculty, which is the seat of their personality. But it is instructive to observe that neither on Kantian principles nor on any other can we demonstrate this; to cross the chasm which separates one man’s personality from another’s requires a venture of faith just as emphatically as any theological formula. I can by no means prove to the determinant Judgement that the complex of sensations which I constantly experience, and which I call the Prime Minister, is anything more than a well-ordered machine. It is improbable that this is the case—highly improbable; but the falsity of such an hypothesis cannot be proved in the same way that we would prove the falsity of the assertion that two and two make five. But then though the hypothesis cannot be thus ruled out of court by demonstration of its absurdity, it is not the simplest hypothesis, nor is it that one which best accounts for the facts. The assumption, on the other hand, that the men whom I meet every day have minds like my own, perfectly accounts for all the facts, and is a very simple assumption. It merely extends by induction the sphere of a force which I already know to exist. Or in other words, crude materialism not giving me an intelligent account of my own individual consciousness, I recognise mind, νοῦς, as a vera causa, as something which really does produce effects in the field of experience, and which therefore I may legitimately put forward as the cause of those actions of other men which externally so much resemble my own. But, as has been said before, this argument, though entirely convincing to any sane person, is not demonstrative; in Kantian language and on Kantian principles the reasoning here used would seem to be valid only for the reflective and not for the determinant Judgement. If the principle of design or conscious adaptation of means to ends be not a constitutive principle of experience, but only a regulative principle introduced to account for the facts, what right have we to put it forward dogmatically as affording an explanation of the actions of other human beings?

      It cannot be said that Kant’s attempted answer to such a defence of the Design Argument is quite conclusive. In § 90 of the Methodology (p. 399) he pleads that though it is perfectly legitimate to argue by analogy from our own minds to the minds of other men,—nay further, although we may conclude from those actions of the lower animals which display plan, that they are not, as Descartes alleged, mere machines—yet it is not legitimate to conclude from the apparent presence of design in the operations of nature that a conscious mind directs those operations. For, he argues, that in comparing the actions of men and the lower animals, or in comparing the actions of one man with those of another, we are not pressing our analogy beyond the limits of experience. Men and beasts alike are finite living beings, subject to the limitations of finite existence; and hence the law which governs the one series of operations may be regarded by analogy as sufficiently explaining the other series. But the power at the basis of Nature is utterly above definition or comprehension, and we are going beyond our legitimate province if we venture to ascribe to it a mode of operation with which we are only conversant in the case of beings subject to the conditions of space and time. He urges in short that when speaking about man and his mind we thoroughly understand what we are talking about; but in speaking of the Mind of Deity we are dealing with something of which we have no experience, and of which therefore we have no right to predicate anything.

      But it is apparent that, as has been pointed out, even when we infer the existence of another finite mind from certain observed operations, we are making an inference about something which is as mysterious an x as anything can be. Mind is not a thing that is subject to the laws and conditions of the world of sense; it is “in the world but not of the world.” And so to infer the existence of the mind of any individual except myself is a quite different kind of inference from that by which, for example, we infer the presence of an electro-magnet in a given field. The action of the latter we understand to a large extent; but we do not understand the action of mind, which yet we know from daily experience of ourselves does produce effects in the phenomenal world, often permanent and important effects. Briefly, the action of mind upon matter (to use the ordinary phraseology for the sake of clearness) is—we may assume for our present purpose—an established fact. Hence the causality of mind is a vera causa; we bring it in to account for the actions of other human beings, and by precisely the same process of reasoning we invoke it to explain the operations of nature.

      And it is altogether beside the point to urge, as Kant does incessantly, that in the latter case the intelligence inferred is infinite; in the former only finite. All that the Design Argument undertakes to prove is that mind lies at the basis of nature. It is quite beyond its province to say whether this mind is finite or infinite; and thus Kant’s criticisms on p. 364 are somewhat wide of the mark. There is always a difficulty in any argument which tries to establish the operation of mind anywhere, for mind cannot be seen or touched or felt; but the difficulty is not peculiar to that particular form of argument with which theological interests are involved.

      The real plausibility of this objection arises from a vague idea, often present to us when we speak of infinite wisdom or infinite intelligence, namely that the epithet infinite in some way alters the meaning of the attributes to which it is applied. But the truth is that the word infinite, when applied to wisdom or knowledge or any other intellectual or moral quality, can only properly have reference to the number of acts of wisdom or knowledge that we suppose to have been performed. The only sense in which we have any right to speak of infinite wisdom is that it is that which performs an infinite number of wise acts. And so when we speak of infinite intelligence, we have not the slightest warrant, either in logic or in common sense, for supposing that such intelligence is not similar in kind to that finite intelligence which we know in man.

      To understand Kant’s attitude fully, we must also take into consideration the great weight that he attaches to the Moral Argument for the existence of God. The positive side of his teaching on Theism is summed up in the following sentence (p. 388): “For the theoretical reflective Judgement physical Teleology sufficiently proves from the purposes of Nature an intelligent world-cause; for the practical Judgement moral Teleology establishes it by the concept of a final purpose, which it is forced to ascribe to creation.” That side of his system which is akin to Agnosticism finds expression in his determined refusal to admit anything more than this. The existence of God is for him a “thing of faith”; and is not a fact of knowledge, strictly so called. “Faith” he holds (p. 409) “is the moral attitude of Reason as to belief in that which is unattainable by theoretical cognition. It is therefore the constant principle of the mind to assume as true that which it is necessary to presuppose
