A man of genius is privileged only as far as he is genius. His dullness is as insupportable as any other dullness. - Ralph Waldo Emerson
To be deceived by our enemies or betrayed by our friends in insupportable; yet by ourselves we are often content to be so treated. - Francois De La Rochefoucauld
I wonder how so insupportable a thing as a bookseller was ever permitted to grow up in the Commonwealth. Many of our modern booksellers are but needless excrements, or rather vermin.
