Wild animals never kill for sport. Man is the only one to whom the torture and death of his fellow creatures is amusing in itself.

The practical effect of a belief is the real test of its soundness.

We live merely on the crust or rind of things.

We cannot live on probabilities. The faith in which we can live bravely and die in peace must be a certainty, so far as it professes to be a faith at all, or it is nothing.

To be happy is not the purpose for which you are placed in this world.

Human improvement is from within outward.

The essence of greatness is neglect of the self.
