To trace the development of mind from earliest times ... requires ... not a categorical concept, but a functional one.... The most promising operational principle for this purpose is the principle of individuation.

... the image of feeling created by artists, in every kind of art -- plastic, musical, poetic, balletic -- serves to hold the reality itself for our labile and volatile memory, as a touchstone to test the scope of our intellectual constructions.

Religion, even the most primitive and superstitious, is inevitably a beginning of culture. It is not possible without some kind of symbolic expression ... and begets dramatic gesture, dance, and chant.

The development of beings with minds is probably the highest individuation the world has ever known, and its prehistory is the history of life on earth.

the wide discrepancy between reason and feeling may be unreal; it is not improbable that intellect is a high form of feeling - a specialized, intensive feeling about intuitions.

Tragedy dramatizes human life as potentiality and fulfillment. Its virtual future, or Destiny, is therefore quite different from that created in comedy. Comic Destiny is Fortune - what the world will bring, and the man will take or miss, encounter or escape; tragic Destiny is what the man brings, and the world will demand of him. That is his Fate.

The limits of thought are not so much set from outside, by the fullness or poverty of experiences that meet the mind, as from within, by the power of conception, the wealth of formulative notions with which the mind meets experiences.
