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.

Most new discoveries are suddenly-seen things that were always there.

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.

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.
