“We have a closed circle of consistency here: the laws of physics produce complex systems, and these complex systems lead to consciousness, which then produces mathematics, which can then encode in a succinct and inspiring way the very underlying laws of physics that gave rise to it.”
― Roger Penrose, The Road to Reality: A Complete Guide to the Laws of the Universe

“Reality is a powerful selection pressure. A hominid that soothed itself by believing that a lion was a turtle or that eating sand would nourish its body would be outreproduced by its reality-based rivals.”
― Steven Pinker, Rationality

“We ought not to do to our future selves what it would be wrong to do to other people.”
― Derek Parfit, Reasons and Persons

“If we care about knowledge, freedom, and peace, then we need to stake a strong claim: anyone can believe anything, but liberal science—open-ended, depersonalized checking by an error-seeking social network—is the only legitimate validator of knowledge, at least in the reality-based community. Other communities, of course, can do all kinds of other things. But they cannot make social decisions about objective reality.

That is a very bold, very broad, very tough claim, and it goes down very badly with lots of people and communities who feel ignored or oppressed by the Constitution of Knowledge: creationists, Christian Scientists, homeopaths, astrologists, flat-earthers, anti-vaxxers, birthers, 9/11 truthers, postmodern professors, political partisans, QAnon followers, and adherents of any number of other belief systems and religions.”
