Nawww, Amos.... when I observe beauty, I am just channeling Plato's 'forms', with sub-context by Aristotle.....(he said, with tongue pressed firmly into cheek)

'beauty' is one of them 'ostensive' concepts....and in some ways it is actually semantic/linguistic. Very handy that many of our nerve channels are stimulated in a similar manner, huh? .....and that we have a word we agree on to refer to the experience.
