envisaged in the primitive demand, it would still imply the tragedy of the world not made for us and the "problem of evil," in which the life of the spirit is persistently a salvage of one of two always incompatible goods, a saving by surrender. And this is all that a mind is--an affair of saving and rejecting, of valuing with a system of objects of which a living body and its desires and operations, its interests, are focal and the objects marginal, for its standard. Mind, thus, is neither simple, nor immutable, nor stable; it is a thing to be "changed," "confused," "cleared," "made-up," "trained." One body, I have written elsewhere,[89] "in the course of its lifetime, has many minds, only partially united. Men are all too often "of two minds." The unity of a mind depends on its consistent pursuit of _one_ interest, although we then call it narrow; or on the cooeperation and harmony of its many interests. Frequently, two or more minds may struggle for the possession of the same body; that is, the body may be divided by two elaborately systematized tendencies to act. The beginning of such division occurs wherever there is a difficulty in deciding between alternative modes of behavior; the end is to be observed in those cases of dual or multiple personality in which the body has ordered a great collection of objects and systematized so large a collection of interests in such typically distinct ways as to have set up for itself different and opposed "minds." On the other hand, two or fifty or a million bodies may be "of the same mind."
