You see, I've seen the word "rationalism" used to mean all five of these things at different times:
- The belief that we should come to know the world through reason and experimentation, shunning intuition.
- The belief that we should come to know the world through reason and intuition, shunning experimentation.
- The belief that we should come to know the world through knowledge of (and correction for) cognitive biases, and knowledge of (and correct use of) probability theory.
- Being effective at believing things that are true and not things that are false.
- Being effective at doing things that are good and not things that are bad.
Edited to reinstate that proposed solution, since this discussion is presumably finished.
Well, you won't have to worry about it unless the grandparent hits 5 karma points, that being the threshold I had privately decided on for doing a discussion post following up on the idea. But if it does come to that, care to state your personal odds for the occurrence of your predicted regress?
Throwing up numbers would just be pointless guessing for the sake of pointless guessing, but because of the tight-knit nature of the blog in question (meaning that people here tend to share the same ideas and values concerning rationality), I'd say that the chances of regression for the LessWrong community would be significantly lower than the chances of regression for two random individuals.
