Rationality is a game. Played within a structure of rules (aka assertions, assumptions, axioms).
These rules are not themselves rationally born. They are born from habit, tradition, convention, aesthetics, consensus, utility, authority... Lots of possible sources for rules.
Logical consistency is one good rule. Puts the rational in rationality.
It's just a game. A dream. Ungrounded. That may be obvious, but it's easy to lose yourself in a dream. (Forever even.) That's important to keep in mind.
