Man is the only animal that laughs and weeps; for he is the only animal that is struck by the difference between what things are and what they might have been.

Genius, like humanity, rusts for the want of use

An inadvertent step may crush the snail That crawls at evening in the public path. But he that has humanity, forewarned, Will turn aside and let the reptile live.

The natural man has only two primal passions: to get and beget.

Never to blend our pleasure or our pride With sorrow of the meanest thing that feels.

But hearing oftentimes The still, sad music of humanity.
