Plausible? Yes. But my personal opinion? No.
I see ideals as the imagined lines on a piece of paper vs the
actual lines we draw that are imperfect, 3D, bumpy under a
magnifying glass.
Reconciling ideal and real is, to me, a fight that happens
within cognitive dissonance... the fight between how we imagine
the world should be vs what we actually experience the world to
be.
Is there a reality "beyond here"? Well, I hope so! But I don't
know myself. What I do know is that the "idea of ideas" from
Plato onwards - of a timeless eternal 'something' that's perfect
and such, whether it be God or mathematics or logic or reason or
Truth or whatever - seems to cause humans much trouble when
people fight with ideologies.
They're useful tools, and good goals; and I honestly hope that
Summum Bonum or something like it exists in an Ultimate reality,
and I hope that an Ultimate reality does exist. But I personally
don't know.
I just want people here to treat each other with respect
whenever possible and leave the ideology for interesting
discussions but not used as weapons that lead to real bloody
ones.
