Do nothing to make you lose respect for yourself, or to cheapen yourself in your own eyes. Let your own integrity be the standard of rectitude, and let your own dictates be stricter than the precepts of any law. Forego the unseemly, more because of outer authority. Learn this fear of yourself, and there will then be no need for that imaginary monitor of Seneca.
~ Baltasar Gracian, The Art of Worldly Wisdom
