Perfection.

Perfection[lat: perfectio] describes the completeness of a state that cannot be further improved. “Complete” takes on a multiple meaning here: on one hand, within the context of flawlessness, i.e. a state free of damage, on the other hand in the sense of completing something or the completion, this means a final result of a series of improvements to be concluded as absolute internal functionality. Both these meanings implicate an unsurpassable state - the flawless or completed state is the maximum of the actual achievable state in each case. It reminds us of the notion of “ideal”.
