Someone should do a post attempting to define what exactly "rationalism" is. Right now I see lots of discussion on how to build rationalist communities, whether rationalism always "wins," why you should be a rationalist, etc., but very little on what the content of this term is, and very little on how to be a rationalist. A newcomer could be excused for thinking that "rationalist" just means someone who goes around exhorting others to become rationalists. Maybe there's nothing wrong with that, though; perhaps rationalism, at its core, is simply reminding yourself and others to think hard about things at all times.
