There seems to be a feeling that anything that is natural is good. Strychnine is natural.

Science is a mechanism, a way of trying to improve your knowledge of nature. It's a system for testing your thoughts against the universe, and seeing whether they match.

Science does not promise absolute truth, nor does it consider that such a thing necessarily exists. Science does not even promise that everything in the Universe is amenable to the scientific process.

To succeed, planning alone is insufficient. One must improvise as well.

You can prove anything you want by coldly logical reason---if you pick the proper postulates.

In life, people will take you at your own reckoning.

I don't believe in personal immortality; the only way I expect to have some version of such a thing is through my books.
