Context: The human imagination leaps to form the whole, to complete the scene in order to make sense of it. The instantaneous way this is done shows how we are driven to construct the remainder of the scene. To fill the gaps is essential if the scene is to have meaning. That we may do this in misleading ways — at times in neurotic or paranoid ways — does not gainsay the central point. Our passion for form expresses our yearning to make the world adequate to our needs and desires, and, more important, to experience ourselves as having significance.

Interview with Einstein (1930)
Context: Our passions and desires are unruly, but our character subdues these elements into a harmonious whole. Does something similar to this happen in the physical world? Are the elements rebellious, dynamic with individual impulse? And is there a principle in the physical world which dominates them and puts them into an orderly organization? … It is the constant harmony of chance and determination which makes it eternally new and living.

Si nous résistons à nos passions, c'est plus par leur faiblesse que par notre force.
If we conquer our passions, it is more from their weakness than from our strength.

Context: You are not a miserable and momentary body; behind your fleeting mask of clay, a thousand-year-old face lies in ambush. Your passions and your thoughts are older than your heart or brain.
