value exists only where there is consciousness. Where nothing ever is felt, nothing matters.

The world of physics is essentially the real world construed by mathematical abstractions, and the world of sense is the real world construed by the abstractions which the sense-organs immediately furnish. To suppose that the "material mode" is a primitive and groping attempt at physical conception is a fatal error in epistemology.

The faith of scientists in the power and truth of mathematics is so implicit that their work has gradually become less and less observation, and more and more calculation.... But the facts which are accepted by virtue of these tests are not actually observed at all.

Pioneering is the work of individuals.

Fire is a natural symbol of life and passion, though it is the one element in which nothing can actually live.

Music is 'significant form,' and its significance is that of a symbol, a highly articulated, sensuous object, which by virtue of its dynamic structure can express the forms of vital experience which language is peculiarly unfit to convey. Feeling, life, motion and emotion constitute its import.

common sense is a very tricky instrument; it is as deceptive as it is indispensable.
