Percy Bysshe Shelley

Only nature knows how to justly proportion to the fault the punishment it deserves.

Poetry lifts the veil from the hidden beauty of the world, and makes familiar objects be as if they were not familiar.

In a drama of the highest order there is little food for censure or hatred; it teaches rather self-knowledge and self-respect.

Revenge is the naked idol of the worship of a semi-barbarous age.

Reason respects the differences, and imagination the similitudes of things.

The great instrument of moral good is the imagination.
