Perhaps, then, you will undertake to overlook the offensive nature of the censored dream-wishes and will fall back upon the argument that it is surely very improbable that we ought to concede so large a part in the human constitution to what is evil. But do your own experiences justify you in this statement? I will say nothing of how you may appear in your own eyes, but have you met with so much goodwill in your superiors and rivals, so much chivalry in your enemies and so little envy amongst your acquaintances, that you feel it incumbent on you to protest against the idea of the part played by egoistic baseness in human nature? Do you not know how uncontrolled and unreliable the average human being is in all that concerns sexual life? Or are you ignorant of the fact that all the excesses and aberrations of which we dream at night are crimes actually committed every day by men who are wide awake? What does psycho-analysis do in this connection but confirm the old saying of Plato that the good are those who content themselves with dreaming of what others, the wicked, actually do? And now look away from individuals to the great war still devastating Europe: think of the colossal brutality, cruelty and mendacity which is now allowed to spread itself over the civilized world. Do you really believe that a handful of unprincipled place-hunters and corrupters of men would have succeeded in letting loose all this latent evil, if the millions of their followers were not also guilty? Will you venture, even in these circumstances, to break a lance for the exclusion of evil from the mental constitution of humanity? You will accuse me of taking a one-sided view of war, and tell me that it has also called out all that is finest and most noble in mankind, heroism, self-sacrifice, and public spirit. That is true; but do not now commit the injustice, from which psycho-analysis has so often suffered, of reproaching it that it denies one thing because it affirms another. It is no part of our intention to deny the nobility in human nature, nor have we ever done anything to disparage its value. On the contrary, I show you not only the evil wishes which are censored but also the censorship which suppresses them and makes them unrecognizable. We dwell upon the evil in human beings with the greater emphasis only because others deny it, thereby making the mental life of mankind not indeed better, but incomprehensible. If we give up the one-sided ethical valuation then, we are sure to find the truer formula for the relation of evil to good in human nature.
