“When making a decision of minor importance, I have always found it advantageous to consider all the pros and cons. In vital matters, however, such as the choice of a mate or a profession, the decision should come from the unconscious, from somewhere within ourselves. In the important decisions of personal life, we should be governed, I think, by the deep inner needs of our nature.”

“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.”

“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.”

“Properly speaking, the unconscious is the real psychic; its inner nature is just as unknown to us as the reality of the external world, and it is just as imperfectly reported to us through the data of consciousness as is the external world through the indications of our sensory organs.”

“As regards intellectual work it remains a fact, indeed, that great decisions in the realm of thought and momentous discoveries and solutions of problems are only possible to an individual, working in solitude.”

“We tell ourselves how lovely it would be, would it not, if there were a God who created the universe and benign Providence, a moral world order, and life beyond the grave, yet it is very evident, is it not, that all of this is the way we should inevitably wish it to be. And it would be even more remarkable if our poor, ignorant bondsman ancestors had managed to solve all these difficult cosmic questions.”

“Thus we arrive at the singular conclusion that of all the information passed by our cultural assets it is precisely the elements which might be of the greatest importance to us and which have the task of solving the riddles of the universe and of reconciling us to the sufferings of life -- it is precisely those elements that are the least well authenticated of any.”
