Those Things That Hurt, Instruct.

The Only Time Not Wasted Is Wasted Time.

Savages We Call Them Because Their Manners Differ From Ours.

All Mankind Is Divided Into Three Classes: Those That Are Immovable, Those That Are Movable, And Those That Move.

This Gave Me Occasion To Observe, That When Men Are Employ'd They Are Best Contented. For On The Days They Work'd They Were Good-natur'd And Chearful; And With The Consciousness Of Having Done A Good Days Work They Spent The Evenings Jollily; But On The Idle Days They Were Mutinous And Quarrelsome, Finding Fault With Their Pork, The Bread, And In Continual Ill-humour. (autobiography, 1771)

Those Who Are Fear'd, Are Hated.
