To me the sole hope of human salvation lies in teaching.

Nature holds no brief for the human experiment; it must stand or fall by its results.

There are two things necessary to Salvation.... Money and gunpowder.

The average age (longevity) of a meat eater is 63. I am on the verge of 85 and still work as hard as ever. I have lived quite long enough and am trying to die; but I simply cannot do it. A single beef-steak would finish me; but I cannot bring myself to swallow it. I am oppressed with a dread of living forever. That is the only disadvantage of vegetarianism.

I must have been an insufferable child; all children are.

You know well I couldn't bear to live with a low common man after you two; and it's wicked and cruel of you to insult me by pretending I could.

Only fools repeat the same things over and over, expecting to obtain different results.
