LittleToe:
If something meets the standard for which it was designed, is that a reasonable definition of perfection?
No, that's a reasonable definition of adequacy.
Like when the first rudimentary wheel was built, and was surely perfect for the job?
No, it was adequate. It was less than perfectly round and was made of a material that wore down over time or warped with changes in temperature or humidity. In fact, that's true of all wheels that have ever actually been built. The perfect wheel is perfectly round, perfectly balanced, and immune to environmental changes - and while we get closer and closer to this, we can never produce such a wheel (the universe's fault, not ours.
Perfection, then, is an ideal which can be appoached but never reached.
