Full Idea
Nor will the Good be any more good by being eternal, if a long-lasting white thing is no whiter than an ephemeral one.

Eternal white is no whiter than temporary white, and it is the same with goodness

A Reaction
A powerful point, made with a hint of sarcasm. You can't add extra Form of White to increase the whiteness of your paint. And the paint is no whiter because it endures for years.
