“Religion is a culture of faith; science is a culture of doubt.”

“Culture is religion externalized.”

“Culture is "lived religion". It is the form that religion takes in the lives of men.”

“Religious faith always transcends culture, and is the integrating principle and power of man's cultural striving.”

“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.”

“If faith cannot be reconciled with rational thinking, it has to be eliminated as an anachronistic remnant of earlier stages of culture and replaced by science dealing with facts and theories which are intelligible and can be validated.”
