We are always searching for perfection, but never finding it. We invent theories of how perfection exists, just not here, no now. Perfection is an illusion.
For the Greek philosopher Plato perfection only existed in Forms and everything in the material world was merely an imperfect image of those Forms. Real perfection existed somewhere other than where we live.
For Christians perfection resides in God. God is perfect and all-knowing, all-loving, and all-powerful. If perfection is an illusion, what is God? Not an illusion, but not an unchanging image of perfection either.
The ACIM (A Course In Miracles) folks have an answer. The world is not real and it is only a dream.
[ACIM] states that everything involving time, space, and perception is as illusory. It presents a nondualism which states that God is the only truth and reality: perfect, unchanging, unchangeable, extending only love, though not in time and space, which can not really be comprehended from a dualistic perspective. –Wikipedia
“Dualism” or “duality” is a big no-no to many into this kind of philosophy. Perfection has to be unchanging (which in itself makes sense) so anything that changes is neither perfect, nor real.
I come to a different conclusion.
