“...science, to quote your own words, is nothing else than a 'strange hankering after differences'. Her essence could not be better defined. For men of science nothing is so important as the clear definition of differences.”

“Almost all of us have the hankering to be famous, to be important, to be admired, to stand out, but the assumption is you have to be different or better to get that. No. The best thing is to be famous, to be cuddled by the public, but to be like everyone else.”

“Different ‘philosophies’ represent nothing but methods of evaluation, which may lead to empirical mis-evaluation if science and empirical facts are disregarded.”

“Science says the first word on everything, and the last word on nothing.”

“There are cultures on Earth that are more alien than some of the aliens in SF.More extensive quote: "the theme of immersion into different cultures comes naturally to science fiction, since a major theme of the genre is how humans interact with 'alien' cultures. Yet many of the so-called alien cultures of science fiction, particularly in its younger days, felt myopic, more like Western cultures even than other cultures on our own planet.”

“The difference between me and a scientist is a little word called “Science.” I don’t believe in it. Science has yet to validate my disbelief in Bigfoot.”
