on perfection

there are at least two kinds of perfection.
one is technical perfection -- that is, perfection that fits perfectly with a very specific and measurable definition of perfection. the other is the opposite (what i call "perceptual perfection", one that does not fit in any technical definition of perfection yet, somehow, feels perfect anyway.
it's best to illustrate the difference through a song, "i feel pretty", from the play "west side story".

and here's a "'perceptively" perfect rendition of the same song. click here.

each has its own place...
