Quote from Gringinho:
Well, in my view - I would call it reasoning; but I would also not connect this to an absolute truth, because as you say - belief in absolute truth (or any universally absolute) is in fact "faith".
What I also pointed out was how the forced and not voluntary "alignment" of others into such belief - is akin to corruption - or "sin" in your religious terms.
Funtionally then, religion and reasoning must be different words for the same thing. Since "religion" has been co-opted and twisted beyond recognition, "reason" might be an effective alternative. I would connect reason to truth inasmuch as reason does lead to truth, and truth is sane and reasonable. If reason does not lead to truth, it must be the kind of *logic* or *rhetoric* that builds and maintains illusion ["the universe"] as "truth". If the will to know truth is greater than the wish to believe lies, then reason will function effectively. If you rule out an absolute universal truth, then, if there is an absolute universal truth, your "reasoning" will not lead to the absolute universal truth.
"The universe" is a lie repeated 24/7, imposing itself as "absolute truth" upon the beguiled, forcing a waffling mind to align with its "reality". As such, it is a "sin". Sin is simply the denial of reality which takes seriously the notion of an insane idea: that what is one can be made many, and that truth can be different for each one. The religio-theist and the reasono-athiest meet on the common battlefield of time, space, form, stars, planets, water, fire, air, "man" and "woman", each more or less agreeing that these are "real", the former by "creation", the latter by "nature", and worth fighting over. Either way, both are "sinners", taking seriously what is really insane, and by these means deny reality, which is also the absolute universal truth.
There is this idea that "reason" could be employed to make what is really insane *work*. Good luck!

In this context, reason is synonymous with ingenuity. Ingenuity takes what is insane seriously, and attempts to make adjustments so that individualism will work.
On the quest for reason, I would posit this axiom which we both may agree on:
What must impose itself through fear, force, or intimidation must be entirely illegitamite.
