“I think of death only with tranquility, as an end. I refuse to let death hamper life. Death must enter life only to define it.”

“Thus, by science I mean, first of all, a worldview giving primacy to reason and observation and a methodology aimed at acquiring accurate knowledge of the natural and social world. This methodology is characterized, above all else, by the critical spirit: namely, the commitment to the incessant testing of assertions through observations and/or experiments — the more stringent the tests, the better — and to revising or discarding those theories that fail the test. One corollary of the critical spirit is fallibilism: namely, the understanding that all our empirical knowledge is tentative, incomplete and open to revision in the light of new evidence or cogent new arguments (though, of course, the most well-established aspects of scientific knowledge are unlikely to be discarded entirely).. . . I stress that my use of the term ‘science’ is not limited to the natural sciences, but includes investigations aimed at acquiring accurate knowledge of factual matters relating to any aspect of the world by using rational empirical methods analogous to those employed in the natural sciences. (Please note the limitation to questions of fact. I intentionally exclude from my purview questions of ethics, aesthetics, ultimate purpose, and so forth.) Thus, ‘science’ (as I use the term) is routinely practiced not only by physicists, chemists and biologists, but also by historians, detectives, plumbers and indeed all human beings in (some aspects of) our daily lives. (Of course, the fact that we all practice science from time to time does not mean that we all practice it equally well, or that we practice it equally well in all areas of our lives.)”

“People are invariably surprised to hear me say I am both an atheist and an agnostic, as if this somehow weakens my certainty. I usually reply with a question like, ‘Well, are you a Republican or an American?’ The two words serve different concepts and are not mutually exclusive. Agnosticism addresses knowledge; atheism addresses belief. The agnostic says, ‘I don’t have a knowledge that God exists.’ The atheist says, ‘I don’t have a belief that God exists.’ You can say both things at the same time. Some agnostics are atheistic and some are theistic.”

“When your only regret is if anyone thinks you regret anything – that is the definition of conviction.”

“In the absence of a formally agreed, worldwide dictionary definition of ‘Quotography’ (in 2016), here are my two cents worth: ‘Quotography is the art of pairing unique quotations with complementary images in order to express thought-provoking ideas, challenging concepts, profound sentiments’.”

“No one knows for sure about the future. But if you feel reluctant to plan something about it, then someone with guts would define it for you.”

“It always seems as though the definition of love will remain debatable by an opinionated world.”

“There are, as we know, powerful and illustrious atheists. At bottom, led back to the truth by their very force, they are not absolutely sure that they are atheists; it is with them only a question of definition, and in any case, if they do not believe in God, being great minds, they prove God.”

“Hash, x. There is no definition for this word – nobody knows what hash is.Famous, adj. Conspicuously miserable.Dictionary, n. A malevolent literary device for cramping the growth of a language and making it hard and inelastic. This dictionary, however, is a most useful work.”
