Benjamin Franklin (170690)
We must not in the course of public life expect immediate approbation and immediate grateful acknowledgment of our services. But let us persevere through abuse and even injury. The internal satisfaction of a good conscience is always present, and time will do us justice in the minds of the people, even those at present the most prejudiced against us.
BENJAMIN FRANKLIN, letter to Joseph Galloway, December 2, 1772.The Works of Benjamin Franklin, ed. Jared Sparks, vol. 8, p. 23 (1839).
