A 'religion' of one, though I honestly don't know how much of it really could be considered a religion; after all, the only leaps of faith I took were leaps of faith in my own abilities to correctly reason and draw conclusions from the data, as well as to correctly act upon said conclusions. Furthermore, I don't have any form of anything that doesn't obey physics, nothing that is not-understandable, given enough time and information and processing power, no circular reasoning (though reflexive reasoning is allowed, such as that 1=1 by the reflexive theorem of equality or whatever it was called. Only known principles of reality were allowed in my derivation of my conclusions.), and no high and mighty omnipotent deities that can make laws up on a whim.
I generally side with the aethists.
