personality become mere ideas, our will and personality themselves become, too, a series of phenomena. Our self is now no longer the purposive will but is that group of sensations and ideas which clusters about the perception of our organism and its actions; in short, our self itself becomes an object of awareness. Our whole inner experience thus becomes a manifold of objects. Our self and the actions of our self are thus alike for the psychologist mere phenomena, mere objects which are perceived. Will and emotion, memory idea and thought--they all are now passing appearances like the sunshine and rain, the flowers and waves. By this transformation the immediate will character of real life is given up, but instead of it a system of objects is gained, that allows description and explanation. If we are to deal at all with inner life not from a purposive but from a causal point of view, we are obliged to admit this reconstruction. Without it we cannot have any science of the mind, without it we can understand the intentions of our neighbor and appreciate the truth and morality of his meanings but we cannot causally explain his experiences or determine which effects are to be expected. It is thus not an arbitrary substitution but a procedure just as necessary and logically obligatory as the work of the chemist who substitutes trillions of invisible atoms for the glass of water which he drinks. The possibility of causal explanation of the successive facts demands this remolding of the outer and of the inner world. We have discussed that before and now only have to draw the consequences.
