Every man’s reason is, and must be, his guide; and I may as well expect that every man should be of my size and complexion, as that he should reason just as I do. Every man seeks for truth; but God only knows who has found it. It is, therefore, as unjust to persecute as it is absurd to ridicule people for those several opinions which they cannot help entertaining upon the conviction of their reason.
Lord Chesterfield (1694-1773) English statesman, wit [Philip Dormer Stanhope]
