Why the Enlightenment is the Ultimate Moral Movement
And knowledge maximalism is the ultimate moral principle.
The growth of knowledge, the moral value that is the distillation and crown jewel of the Enlightenment, is a special value because it intrinsically tends toward self-correction. All other value systems must be defended by some additional steps—some arguments or evidence on behalf of some metaethical framework—none of which have thus far been quite satisfactory. The pursuit of any value other than knowledge, if misguided, must be corrected by new knowledge.
If there was anything wrong with the intellectual movement known as the Enlightenment (and indeed, plenty of errors were made), the solution was and is more enlightenment.
Knowledge maximalism, likewise, if in need of correction and if followed long enough, will correct itself from within. Misguided knowledge maximalists are mandated by the value they already follow to eventually discover their error; the more knowledge maximalism, the sooner the correction.
