Be sure of the fact before you lose time in searching for a cause. - James Burgh

Do not think of knocking out another person's brains because he differs in opinion from you. It would be as rational to knock yourself on the head because you differ from yourself ten years ago.

There is an affected humility more unsufferable than downright pride, as hypocrisy is more abominable than libertimsm. Take care that your virtues be genuine and unsophisticated.

If you would have a right to account of things from illiterate people, let them tell their story in their own way; if you put them upon talking according to logical rules, you will confound them.
