“We are never so defenseless against suffering as when we love.”

“It is that we are never so defenseless against suffering as when we love, never so helplessly unhappy as when we have lost our loved object or its love.”

“Illusions commend themselves to us because they save us pain and allow us to enjoy pleasure instead. We must therefore accept it without complaint when they sometimes collide with a bit of reality against which they are dashed to pieces.”

“Our possibilities of happiness are already restricted by our constitution. Unhappiness is much less difficult to experience. We are threatened with suffering from three directions: from our own body, which is doomed to decay and dissolution and which cannot even do without pain and anxiety as warning signals; from the external world, which may rage against us with overwhelming and merciless forces of destruction; and finally from our relations to other men. The suffering which comes from this last source is perhaps more painful to us than any other.”

“We need not deplore the renunciation of historical truth when we put forward rational grounds for the precepts of civilization. The truths contained in religious doctrines are after all so distorted and systematically disguised that the mass of humanity cannot recognize them as truth. The case is similar to what happens when we tell a child that new-born babies are brought by the stork. Here, too, we are telling the truth in symbolic clothing, for we know what the large bird signifies . But the child does not know it. He hears only the distorted part of what we say, and feels that he has been deceived; and we know how often his distrust of the grown-ups and his refractoriness actually take their start from this impression. We have become convinced that it is better to avoid such symbolic disguisings of the truth in what we tell children and not to withhold from them a knowledge of the true state of affairs commensurate with their intellectual level.”

“We are so constituted that we can gain intense pleasure only from the contrast, and only very little from the condition itself.”

“Here libido and ego-interest share the same fate and have once more become indistinguishable from each other. The familiar egoism of the sick person covers them both. We find it so natural because we are certain that in the same situation we should behave in just the same way. The way in which the readiness to love, however great, is banished by bodily ailments, and suddenly replaced by complete indifference, is a theme which has been sufficiently exploited by comic writers.”
