MS.
Work is the best healer of sorrow. In grief or disappointment try hard work; it will not fail you.
Autobiography.
No sensible man ought to care about posthumous praise, or posthumous blame. Enough for the day is the evil thereof. Our contemporaries are our right judges, our peers have to give their votes in the great academies and learned societies, and if they on the whole are not dissatisfied with the little we have done, often under far greater difficulties than the world was aware of, why should we care for the distant future?
Autobiography.
Put your whole heart, or your whole love into your work. Half-hearted work is really worse than no work.

Much of the best work in the world is done by those whose names remain unknown, who work because life's greatest bliss is work, and who require no reward beyond the consciousness that they have enlarged the knowledge of mankind and contributed their share to the final triumph of honesty and truth.
