Beauty is a feeling.

Had we not looked at the rose would it have been beautiful?

Had the name of rose not been rose but instead it would have been something else then would we have loved it?

Nothing matters with the name.

If we look at the rose and say it's beautiful then it becomes beautiful.

Beauty lies in the eyes of the beholder.

Whatever creates happiness in our mind that is beautiful.

All the feelings are being controlled by hormones. So, the feeling of beauty, form, flavour, fragrance, touch, music every feeling is the creation of hormones. In one word we can say everything is illusion.
