If we apply this very simple rule of logic to the theory of "unconscious ideas," we at once realize the illegitimate character of such a hypothesis. An idea is essentially of a conscious nature. To speak, therefore, of unconscious ideas, is to introduce into psychology the self-contradictory impossible concept of unconscious conscious ideas. This is equivalent to the assumption of an unconscious consciousness. An unconscious idea is neither a vera causa nor a fact ultimately to be verified. The conception of an unconscious idea is like the conception of a round square.

It is not true that we suppress painful ideas into the "unconscious." We do not forget our painful ideas. On the contrary, painful ideas stand out all the more prominent in our consciousness. Pain hammers experience into the mind. In fact we may say with more right that it is the pleasurable ideas that are forgotten, while the painful ideas are remembered. An experience associated with pain is never forgotten. Like a splinter in the flesh, it remains in consciousness. It is due to other causes that a painful experience becomes subconscious.

A scientific hypothesis should at least have the merit of being rational, logical, and not conceived in a wild harum-scarum fashion. A good scientific hypothesis must have restrictions and definite conditions. I think it is Huxley who says that in the case of stolen goods two hypotheses are at hand: one hypothesis is that an angel is responsible for it, and the other that a thief has carried off the goods. The angel-hypothesis is hardly considered by science. In other words, the hypothetical causative agency must be conceived in terms of experience.
