Kant's style is so heavy that after his pure reason, the reader longs for unreasonableness.

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.

Hope is nature's veil for hiding truth's nakedness.
