Genius is rarely able to give any account of its own processes.

Philosophy and Art both render the invisible visible by imagination.

Insight is the first condition of Art.

Personal experience is the basis of all real Literature.

Science is the systematic classification of experience.

Insincerity is always weakness; sincerity even in error is strength.

Originality is independence, not rebellion; it is sincerity, not antagonism.

Books minister to our knowledge, to our guidance, and to our delight, by their truth, their uprightness, and their art.

Sincerity is moral truth.

The only cure for grief is action.

Imagination is not the exclusive appanage of artists, but belongs in varying degrees to all men.
