"In the night of death, hope sees a star, and listening love can hear the rustle of a wing." — Robert Green Ingersoll

When the will defies fear, when duty throws the gauntlet down to fate, when honor scorns to compromise with death - that is heroism.

Reason, observation, and experience; the holy trinity of science.

Most people can bear adversity; but if you wish to know what a man really is give him power.

In nature there are neither rewards nor punishments; there are consequences.
