According to Rationality (1989) by Nicholas Rescher, who is for all intents and purposes a rationalist in the sense LW (not academic philosophy) uses the word, the LW rationality is a faith based ideology. See confirmation holism by Quine, outlined in “The Two Dogmas of Empiricism”. Rationality is insufficient to justify rationality with rational means, because to do so would presuppose that all means of justification are rational, which already implicitly assumes rationality. Hence, it cannot be refuted that rationality is based on faith. Rescher urges people to accept rationality nevertheless.
