Ideal
We might be better off without the ideal.
There may in fact be no ideal other than the ancient philosophical notion of the ideal.
Without the ideal it is easier to imagine living in a world of imperfection, and to actually live there without feeling the need to upgrade it to the level of the ideal.
Objects would no longer have to the imbued with the idea that some other thing stood within them--the form behind the form--and could just be what they are.
