It seems to follow from my own theory that humans can only perceive that which is useful to them.
Again, not your theory. This is a teleological fallacy much like humans believing that everything around them exists because of them. We cannot perceive gamma rays yet they are useful to us because we have discovered them through an intermediate tool. Based on your logic you can actually imply that anything that can be perceived can have a use. Again. bullshit philosophy. TELEOLOGY.
and
NOT. YOUR. THEORY. ..just because you call bullshit rhetorics "your theory" it doesn't mean they are.
As for the "invention of superiority". Yet again. Bullshit rhetorics. You tried to mimic Ernest Becker's narrative about humans being immortality projects yet it doesn't touch the essence because really you can call anything "the most important invention" and still be valid. Anything can be reasoned as such.
The aspect of expressing superiority exists in every living organism and does not need to be "invented". It is bounded to survival instincts and trying to prevail upon one another.
(again another bullshit post, a desperate attempt to prove that survival instincts do not exist. You reached a point to even call superiority...an invention (FFS) just to go contra against survival instincts...
..idiotic as fuck. new low).
