As All Art Depends On Vision, So

Genius Is Rarely Able To Give Any Account Of Its Own Processes.

No Man Ever Made A Great Discovery Without The Exercise Of The Imagination.

A Man May Be Variously Accomplished, And Yet Be A Feeble Poet.

The Mathematician Who Is Without Value To Mathematicians, The Thinker Who Is Obscure Or Meaningless To Thinkers, The Dramatist Who Fails To Move The Pit, May Be Wise, May Be Eminent, But As An Author He Has Failed.

In Complex Trains Of Thought Signs Are Indispensable.
