Lying is the greatest of all sins.

The slickest way in the world to lie is to tell the right amount of truth at the right time-and then shut up.

One can state, without exaggeration, that the observation of and the search for similarities and differences are the basis of all human knowledge.

I am a misanthrope and yet utterly benevolent, have more than one screw loose yet am a super-idealist who digests philosophy more efficiently than food.

If I have a thousand ideas and only one turns out to be good, I am satisfied.

I have not the slightest pretension to call my verses poetry; I write now and then for no other purpose than to relieve depression or to improve my English.
