Commendation heals; condemnation destroys.

I use [Heraclitus' discovery of] enantiodromia for the emergence of the unconscious opposite in the course of time. This characteristic phenomenon practically always occurs when an extreme, onesided tendency dominates conscious life; in time an equally powerful counterposition is built up, which first inhibits the conscious performance and subsequently breaks through the conscious control.

I have never since entirely freed myself of the impression that this life is a segment of existence which is enacted in a three-dimensional boxlike universe especially set up for it.

The time is a critical one, for it marks the beginning of the second half of life, when a metanoia, a mental transformation, not infrequently occurs. (on being 36 yrs old)

Nobody doubts the importance of conscious experience; why then should we doubt the significance of unconscious happenings? They also are part of our life, and sometimes more truly a part of it for weal or woe than any happenings of the day.

The cinema, like the detective story, makes it possible to experience without danger all the excitement, passion and desirousness which must be repressed in a humanitarian ordering of life.

Nothing is possible without love.
