Utter Simplicity

Nothing could be simpler than the axioms of reason on an epistemological or metaphysical level.  As the only possible inherent truths, for even logical truths other than axioms hinge on them though all are intrinsic, there is nothing that logical necessities reduce down to.  All else reduces down to them, dependent on them despite all other metaphysical existents being distinct, from God to matter.  They do not break down into anything more fundamental, basic, or deep.  Axioms and other logical necessities (the latter not being epistemologically self-evident) are in one sense supremely simple.

Because of this, nothing else can be known apart from them, and to believe in anything at all without avoiding all assumptions and recognizing axioms and what follows from them is to be irrational.  As easily and universally accessible as reason is, it still cannot be discovered or focused on apart from intentional effort, which is precisely why most people are not rationalists in spite of reason's obvious inherent truth, absolute certainty, pragmatic benefits, and omnipresence: they would have to put effort into so much as realizing that any belief not wholly grounded in reason is invalid.  That axioms are self-evident and that reason is metaphysically true by necessity in itself does not mean any of this will be sought out.

There is still great nuance connected with this ultimate simplicity of axioms.  Not only is reason still knowable through intentional rationality rather than assumptions or passive experiences despite its grand simplicity, but it also remains highly abstract and maximally foundational.  Nothing could possibly be deeper, more all-encompassing, more important, or more supreme in all ways than the logical truths that could not be or have been any other way.  Reason, both axioms and the other necessary truths that stem from them, have the greatest kind of simplicity and the greatest kind of significance all the same.

The fact that something that follows from another cannot be false (then it would follow from something that reason is false, which would still be a logical necessity) and that it is impossible for nothing to be true (then this itself would still be true), to touch on two axioms, also necessitates that logical axioms exist in the absence of all else.  This is a truth about logical axioms that follows from the more apparent self-evidence of them on the epistemological side, meaning that axioms have this nature by default although the epistemological side and the more basic metaphysical truth are self-evident (in that to be absolutely certain and self-evident, something must be metaphysically true, but to know this is not to know that reason exists in this other kind of way).  Inherently connected with what is more obvious and yet more precise than what is self-verifying, the fact that logical truths are fully independent truths and their own metaphysical existents is another nuance to the simplicity of reason.  As simple as it is, logic has more qualities than simplicity.

Of course, all nuance regarding any other truth, any other existent besides the laws of logic, any other concept, or any other issue is rooted in the necessities and possibilities governed by reason anyway.  There is depth, nuance, and all-encompassing metaphysical and epistemological significance tied to this most core and weighty type of simplicity.  Reason is intrinsic to reality and nothing else is except in the ways that are logically necessary.  Reason is not grounded in anything more foundational than itself.  No, it is what everything else must be consistent with in order to merely be possible.  Utter simplicity and ultimate nuance are both inevitable components of the nature of intrinsically true, epistemologically self-evident axioms.
