The hunger for facile wisdom is the root of all false philosophy.

There is wisdom in turning as often as possible from the familiar to the unfamiliar: it keeps the mind nimble, it kills prejudice, and it fosters humor.

Facts are all accidents. They all might have been different. They all may become different. They all may collapse altogether.

The love of all-inclusiveness is as dangerous in philosophy as in art.

An artist is a dreamer consenting to dream of the actual world.

The whole machinery of our intelligence, our general ideas and laws, fixed and external objects, principles, persons, and gods, are so many symbolic, algebraic expressions. They stand for experience; experience which we are incapable of retaining and surveying in its multitudinous immediacy. We should flounder hopelessly, like the animals, did we not keep ourselves afloat and direct our course by these intellectual devices. Theory helps us to bear our ignorance of fact.

The loftiest edifices need the deepest foundations.
