Night is the other half of life, and the better half.

When I consider the narrow limits within which our active and inquiring faculties are confined; when I see how all our energies are wasted in providing for mere necessities, which again have no further end than to prolong a wretched existence; and then that all our satisfaction concerning certain subjects of investigation ends in nothing better than a passive resignation... when I consider all this... I am silent.

Nothing is more damaging to the truth than an old error.

It is in vain that a man of sound mind and cool temper understands the condition of such a wretched being... He can no more communicate his own wisdom to him than a healthy man can instil his strength into the invalid by whose bedside he is seated.

Until one is committed, there is hesitancy, the chance to draw back, always ineffectiveness. Concerning all acts of initiation - creation - there is one elementary truth, the ignorance of which kills countless ideas and splendid plans.

If the whole world I once could see On free soil stand, with the people free Then to the moment might I say, Linger awhile. . .so fair thou art.

Patriotism corrupts history.
