“Unexpressed emotions will never die. They are buried alive and will come forth later in uglier ways.”

“Actually, the substitution of the reality-principle for the pleasure-principle denotes no dethronement of the pleasure-principle, but only a safeguarding of it. A momentary pleasure, uncertain in its results, is given up, but only in order to gain in the new way an assured pleasure coming later. But the end psychic impression made by this substitution has been so powerful that it is mirrored in a special religious myth. The doctrine of reward in a future life for the—voluntary or enforced—renunciation of earthly lusts is nothing but a mythical projection of this revolution in the mind. In logical pursuit of this prototype, religions have been able to effect the absolute renunciation of pleasure in this life by means of the promise of compensation in a future life; they have not, however, achieved a conquest of the pleasure-principle this way. It is science which comes nearest to succeeding in this conquest; science, however, also offers intellectual pleasure during its work and promises practical gain at the end.”

“I can imagine that the oceanic feeling could become connected with religion later on. That feeling of oneness with the universe which is its ideational content sounds very like a first attempt at the consolations of religion, like another way taken by the ego of denying the dangers it sees threatening it in the external world.”

“In this way the ego detaches itself from the external world. It is more correct to say: Originally the ego includes everything, later it detaches from itself the external world. The ego-feeling we are aware of now is thus only a shrunken vestige of a far more extensive feeling - a feeling which embraced the universe and expressed an inseparable connection of the ego with the external world.”

“Dream's evanescence, the way in which, on awakening, our thoughts thrust it aside as something bizarre, and our reminiscences mutilating or rejecting it—all these and many other problems have for many hundred years demanded answers which up till now could never have been satisfactory.”

“Words have a magical power. They can bring either the greatest happiness or deepest despair; they can transfer knowledge from teacher to student; words enable the orator to sway his audience and dictate its decisions. Words are capable of arousing the strongest emotions and prompting all men's actions.”

“Out of your vulnerabilities will come your strength.”
