Instantly the book becomes noxious: the guide is a tyrant. Ralph Waldo Emerson, The American Scholar

Inaction is cowardice, but there can be no scholar without the heroic mind. Ralph Waldo Emerson, The American Scholar

In enforcing a truth, we need severity rather than efflorescence of language. We must be simple, precise, terse. We must be cool, calm, unimpassioned. In a word, we must be in that mood which, as nearly as possible, is the exact converse of the poetical. Edgar Allan Poe, The Poetic Principle
Abstractions may amuse and exercise, but take no hold on the mind. Edgar Allan Poe, Mesmeric Revelation
It is the nature of thought to be irrevocable. Edgar Allan Poe, Mesmeric Revelation
