Old age is not a matter for sorrow. It is matter for thanks if we have left our work done behind us.

It were a real increase of human happiness, could all young men from the age of nineteen be covered under barrels, or rendered otherwise invisible and there left to follow their lawful studies and callings, till they emerged, sadder and wiser, at the age of twenty-five.

None of us will ever accomplish anything excellent or commanding except when he listens to this whisper which is heard by him alone.

Doubt, of whatever kind, can be ended by action alone.

Work alone is noble.
