A man may be buoyed up by the efflation of his wild desires to brave any imaginable peril; but he cannot calmly see one he loves braving the same peril; simply because he cannot feel within turn that which prompts another. He sees the danger, and feels not the power that is to overcome it.

Many a genius has been slow of growth. Oaks that flourish for a thousand years do not spring up into beauty like a reed.

In Science the paramount appeal is to the Intellect-its purpose being instruction; in Art, the paramount appeal is to the Emotions-its purpose being pleasure.

A man may be buoyed up by the efflation of his wild desires to brave any imaginable peril; but he cannot calmly see one he loves braving the same peril; simply because he cannot feel within turn that which prompts another. He sees the danger, and feels not the power that is to overcome it.

Vehemence without feeling is but rant.
