"As for us, ordinary men, on whom Heaven has not been pleased to bestow such great talents; as we are not destined to reap such glory, let us remain in our obscurity. Let us not covet a reputation we should never attain, and which, in the present state of things, would never make up to us for the trouble it would have cost us, even if we were fully qualified to obtain it. Why should we build our happiness on the opinions of others, when we can find it in our own hearts? Let us leave to others the task of instructing mankind in their duty, and confine ourselves to the discharge of our own."
