Man was destined for society. His morality therefore was to be formed to this object. He was endowed with a sense of right and wrong merely relative to this. This sense is as much a part of his nature as the sense of hearing, seeing, feeling; it is the true foundation of morality... The moral sense, or conscience, is as much a part of man as his leg or arm.

It may be strengthened by exercise, as may any particular limb of the body.

Traveling makes men wiser, but less happy.

It is true that in the meantime we are suffering deeply in spirit, and incurring the horrors of a war and long oppressions of enormous public debt.
