There is a chapter in the Tao that says: When the world knows beauty as beauty, ugliness arises
When it knows good as good, evil arises
Thus being and non-being produce each other
Difficult and easy bring about each other
Long and short reveal each other
High and low support each other
Music and voice harmonize each other
Front and back follow each other
I think that fits what you're saying perfectly.
