I think I get what you're saying - self-consistency as the surest slippery slope to false dogma; something which purports to hold all the answers within itself can be an easy refuge for the person who can't be bothered to examine and question. This is the most seductive aspect of a great deal of what Guenon and his "disciple" Evola propound, that's for sure.

However I would also say that some manner of self-consistency is a necessary condition for a maintenance of ideals, something which is tied intimately to the question of what is honorable and what isn't; but I suppose then that this pertains more to the personal aptitude for creating cosmos out of chaos rather than allegiance to a more or less "complete" set of beliefs.

Hmm. More food for though, that's for sure.
