I am in favor of deliberately spreading methodically prepared bacteria among people and animals -- mildew ... to destroy the harvests, anthrax to destroy horses and livestock, and the plague, in order to kill not only entire armies, but also the inhabitants of large regions.

Never give in. Never give in. Never, never, never, never -- in nothing, great or small, large or petty -- never give in, except to convictions of honor and good sense.

Everything trends towards catastrophe & collapse. I am interested, geared up & happy. Is it not horrible to be built like that?

Everyone threw the blame on me ... they nearly always do. I suppose ... they think I shall be able to bear it best.

The truth is incontrovertible. Malice may attack it, ignorance may deride it, but in the end, there it is.

The farther backward you can look, the farther forward you can see.

The power of man has grown in every sphere, except over himself.
