Kant defines an act of volition as an act which is determined by the anticipatory idea of the result of the act. Although he maintains that there must be a moral God, he fully admits that the forecast or anticipatory idea is the inevitable effect of precedent conditions, such as temperament (heredity), education (environment), and the like; and in a well-known passage he says that, if the whole history of the subject could be known, the voluntary acts of a man might be predicted with the same certainty as an eclipse. The tendency of modern psychology is in the same direction. All voluntary acts, we are told, depend on the memory of involuntary acts of the same sort previously performed. It is true that a few Christian psychologists leave room for a "sheer heave" of the will by means of which an idea naturally feeble is fortified and held in place; but when they speak in this wise they speak as metaphysicians. No metaphysical argument, it seems to me, can reconcile this inflexible causality with true freedom of will. How can the will be at one and the same time fettered and free? There is, I grant, every appearance of freewill; but it belongs to the category of appearances which deceive. If we accept the Christian contention, we have to believe that a benevolent God gives us a free will, the power to choose between Him and the Devil, knowing, as in His omniscience He must, that the vast majority will make a sad use of their gift! The modern Christian admits that heredity and environment have their say also. Thus there are, in all, four forces struggling for the mastery--God, the Devil, heredity and environment; and it is the duty of the divinely-implanted free will to choose between them. Rather, is it not that there are two forces, and two forces only--heredity and environment--acting upon our brain, and our choice is the resultant of them? Undoubtedly man, as a self-conscious and reflecting animal, has what may be called the power of choice; but the way this power will be used would be a foregone conclusion did we know the sum-total of the effect of heredity and environment up to the moment of its use. "But," it may be objected, "surely there is such a thing as will-power. We can overcome our heredity and environment by the exercise of our will. Temptations to which the weak-willed succumb do not affect the strong-willed. Here, at least, we have a distinct instance in which heredity and environment are overcome." Yes, it is true, of course, that heredity and environment are continually being overcome by the happy possessor of sufficient will-power; but what we have to bear in mind is that it is not a portion, but the whole, of a man's heredity and environment which must be taken into consideration. In the case of the man with the strong will, it is still his heredity and environment which have in the first instance settled the line of conduct to which, once resolved upon, he adheres so tenaciously. And,
