“I would say that the ability of people to agree on matters of fact not immediately visible—states of affairs removed from them in space and time—ramped up from a baseline of approximately zero to a pretty high level around the time of the scientific revolution and all that, and stayed there and became more globally distributed up through the Cronkite era, and then dropped to zero incredibly quickly when the Internet came along.”
― Neal Stephenson, Fall; or, Dodge in Hell

“One can speculate that the tardiness and wobbliness of humanity's progress on many of the "eternal problems" of philosophy are due to the unsuitability of the human cortex for philosophical work. On this view, our most celebrated philosophers are like dogs walking on their hind legs - just barely attaining the treshold level of performance required for engaging in the activity at all.”

“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.”
