Context: Science makes no pretension to eternal truth or absolute truth; some of its rivals do. That science is in some respects inhuman may be the secret of its success in alleviating human misery and mitigating human stupidity.

General sources
Context: Science doesn't purvey absolute truth. Science is a mechanism. It's 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. And this works, not just for the ordinary aspects of science, but for all of life. I should think people would want to know that what they know is truly what the universe is like, or at least as close as they can get to it.
The Act of Creation, London, (1970) p. 253.
Context: Einstein's space is no closer to reality than Van Gogh's sky. The glory of science is not in a truth more absolute than the truth of Bach or Tolstoy, but in the act of creation itself. The scientist's discoveries impose his own order on chaos, as the composer or painter imposes his; an order that always refers to limited aspects of reality, and is based on the observer's frame of reference, which differs from period to period as a Rembrant nude differs from a nude by Manet.

“A bizarre sensation pervades a relationship of pretense. No truth seems true.”
Singin' and Swingin' and Gettin' Merry Like Christmas (1976), chapter 5.
Context: A bizarre sensation pervades a relationship of pretense. No truth seems true. A simple morning's greeting and response appear loaded with innuendo and fraught with implications.... Each nicety becomes more sterile and each withdrawal more permanent.
“Truth is absolute, truth is supreme, truth is never disposable in national political life.”
