What I'm saying is that even as it relates to aspects of people, or the actions they perform, based off whatever morality they follow, perfection is not achievable (see above quote from da Vinci). Greatness worthy of respect? Yes. Amazing deeds and ideas? Yes. But perfection? No. If you or anyone else has a different concept of what a word means than its actual meaning then that is up to you. But it doesn't make that concept correct and certainly doesn't make that concept easy to communicate to others who do not share your non-standard definition.

If one has to redefine the meaning of a word for ones philosophy to make sense, then maybe it's just best to use a different word and save everyone some time.

It appears that the meaning of the word "perfect" seems to be very elastic indeed, as it relates to it's use in Objectivism. One moment it actually does mean "perfect" as in "so good that further improvement is impossible" and the next it becomes this "relative" term, of fluid meaning.

Interesting.
