But that the dreamers should feel the exact opposite of the ascribed wish, and should be able to prove to us the dominance of the opposite tendency--this fact must finally disconcert us. Is it not time to lay aside the whole work of the dream interpretation as something whose results reduce it to absurdity? By no means; this stronger argument breaks down when we attack it critically. Assuming that there are unconscious tendencies in the psychic life, nothing is proved by the ability of the subject to show that their opposites dominate his conscious life. Perhaps there is room in the psychic life even for antithetical tendencies, for contradictions which exist side by side, yes, possibly it is just the dominance of the one impulse which is the necessary condition for the unconsciousness of its opposite. The first two objections raised against our work hold merely that the results of dream interpretation are not simple, and very unpleasant. In answer to the first of these, one may say that for all your enthusiasm for the simple solution, you cannot thereby solve a single dream problem. To do so you must make up your mind to accept the fact of complicated relationships. And to the second of these objections one may say that you are obviously wrong to use a preference or a dislike as the basis for a scientific judgment. What difference does it make if the results of the dream interpretation seem unpleasant, even embarrassing and disgusting to you? "That doesn't prevent them from existing," as I used to hear my teacher Charcot say in similar cases, when I was a young doctor. One must be humble, one must keep personal preferences and antipathies in the background, if one wishes to discover the realities of the world. If a physicist can prove to you that the organic life of this planet must, within a short period of time, become completely extinct, do you also venture to say to him, "That cannot be so. This prospect is too unpleasant." On the contrary, you will be silent until another physicist proves some error in the assumptions or calculations of the first. If you reject the unpleasant, you are repeating the mechanism of dream construction instead of understanding and mastering it.
