In thirty years I have treated many patients. Among all my patients in the second half of life, every one of them fell ill because he had lost that which the living religions of every age had given their followers, and none of them was really healed who did not regain his religious outlook.

The debt we owe to the play of imagination is incalculable.

Plants were bound for good or ill to their places. They expressed not only beauty but also the thoughts of God's world, with an intent of their own and without deviation. Trees in particular were mysterious and seemed to me direct embodiments of the incomprehensible meaning of life. For that reason, the woods were the places where I felt closest to its deepest meaning and to its awe-inspiring workings.

It is on the whole probably that we continually dream, but that consciousness makes such a noise that we do not hear it.

Special knowledge is a terrible disadvantage.

If you should see people in a room, you would not think that you had made those people, or that you were responsible for them.

Science...is part and parcel of our knowledge and obscures our insight only when it holds that the understanding given by it is the only kind there is.
