Full Idea
Anyone who tried to divorce the beautiful from man's pleasure in man would at once feel the ground give way beneath him. The 'beautiful in itself' is not even a concept, merely a phrase.
Gist of Idea
The beautiful never stands alone; it derives from man's pleasure in man

A Reaction
I love the insult 'not even a concept'! It's like Pauli's 'not even wrong'!
