Instinct is intelligence incapable of self-consciousness.

Poetry is in itself strength and joy, whether it be crowned by all mankind, or left alone in its own magic hermitage.

Color, in the outward world, answers to feeling in man; shape, to thought; motion, to will. The dawn of day is the nearest outward likeness of an act of creation; and it is, therefore, also the closest type in nature for that in us which most approaches to creation--the realization of an idea by an act of the will.

Pain has its own noble joy, when it starts a strong consciousness of life, from a stagnant one.

Enthusiasm is grave, inward, self-controlled; mere excitement, outward, fantastic, hysterical, and passing in a moment from tears to laughter.
