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.

Love and work, work and love...that's all there is.

In the development of mankind as a whole, just as in individuals, love alone acts as the civilizing factor in the sense that it brings a change from egoism to altruism.

All family life is organized around the most damaged person in it.

Only the real, rare, true scientific minds can endure doubt, which is attached to all our knowledge.

There is no doubt that the resistance of the conscious and unconscious ego operates under the sway of the pleasure principle: it seeks to avoid the unpleasure which would be produced by the liberation of the repressed.
