Note 34 — Chapter VI

With this distinction clearly understood, I may now proceed to observe that in everyday life we constantly apply the test of relative inconceivability as a test of truth. And in the vast majority of cases this test of relative inconceivability is, for all practical purposes, as valid a test of truth as is the test of absolute conceivability. For as every man is more or less in harmony with his environment, his habits of thought with regard to his environment are for the most part stereotyped correctly; so that the most ready and the most trustworthy gauge of probability that he has is an immediate appeal to consciousness as to whether he feels the probability. Thus every man learns for himself to endow his own sense of probability with a certain undefined but massive weight of authority. Now it is this test of relative conceivability which all men apply in varying degrees to the question of Theism. For if, from education and organised habits of thought, the probability in this matter appears to a man to incline in a certain direction, when this probability is called in question, the whole body of this organised system of thought rises in opposition to the questioning, and being individually conscious of this strong feeling of subjective opposition, the man declares the sceptical propositions to be more inconceivable to him than are the counter-propositions. And in so saying he is, of course, perfectly right. Hence I conceive that the acceptance or the rejection of metaphysical teleology as probable will depend entirely upon individual habits of thought. The test of absolute inconceivability making equally for and against the doctrine of Theism, disputants are compelled to fall back on the test of relative inconceivability; and as the direction in which the more inconceivable proposition will here seem to lie will be determined by previous habits of thought, it follows that while to a theist metaphysical teleology will appear a probable argument, to an atheist it will appear an improbable one. Thus to a theist it will no doubt appear more conceivable that the Supreme Mind should be such that in some of its attributes it resembles the human mind, while in other of its attributes—among which he will place omnipresence, omnipotence, and directive agency—it transcends the human mind as greatly as the latter "transcends mechanical motion;" and therefore that although it is true, as a matter of logical terminology, that we ought to designate such an entity "Not mind" or "Blank," still, as a matter of psychology, we may come nearer to the truth by assimilating in thought this entity with the nearest analogies which experience supplies, than by assimilating it in thought with any other entity—such as force or matter—which are felt to be in all likelihood still more remote from it in nature. On the other hand, to an atheist it will no doubt appear more conceivable, because more simple, to accept the dogma of an eternal self-existence of something which we call force and matter, and with this dogma to accept the implication of a necessary self-evolution of cosmic harmony, than to resort to the additional and no less inconceivable supposition of a self-existing Agent which must be regarded both as Mind and as Not-mind at the same time. But in both cases, in whatever degree this test of relative inconceivability of a negative is held by the disputants to be valid in solving the problem of Theism, in that degree is each man entitled to his respective estimate of the probability in question. And thus we arrive at the judgment that the rational probability of Theism legitimately varies with the character of the mind which contemplates it. For, as the test of absolute inconceivability is equally annihilative in whichever direction it is applied, the test of relative inconceivability is the only one that remains; and as the formal conditions of a metaphysical teleology are undoubtedly present on the one hand, and the formal conditions of a physical explanation of cosmic harmony are no less undoubtedly present on the other hand, it follows that a theist and an atheist have an equal right to employ this test of relative inconceivability. And as there is no more ultimate court of appeal whereby to decide the question than the universe as a whole, each man has here an equal argumentative right to abide by the decision which that court awards to him individually—to accept whatever probability the sum-total of phenomena appears to present to his particular understanding. And it is needless to say that experience shows, even among well-informed and accurate reasoners, how large an allowance must thus be made for personal equations. To some men the facts of external nature seem to proclaim a God with clarion voice, while to other men the same facts bring no whisper of such a message. All, therefore, that a logician can here do is to remark, that the individuals in each class—provided they bear in mind the strictly relative character of their belief—have a similar right to be regarded as holding a rational creed: the grounds of belief in this case logically vary with the natural disposition and the subsequent training of different minds.[34]
