No man should so act as to make a gain out of the ignorance of another.

I never heard of an old man forgetting where he had buried his money. Old people remember what interests them: the dates fixed for their lawsuits, and the names of their debtors and creditors.

All great men are partially inspired.

Work makes a callus against grief.

I cheerfully quit from life as if it were an inn, not a home; for Nature has given us a hostelry in which to sojourn, not to abide.

Not only is there an art in knowing a thing, but also a certain art in teaching it.

No grief is so acute but time ameliorates it.
