Why do many students of art accept more than one aesthetic view?

Knowing that There are many more views, i would say many students would pick different views because many people are different

Because some people view different things to be beautiful. For example, some people like still life paintings and colorless sketches while others might find these to be too bland. Or, some people like poetry and others see it as corny or too dramatic. We all find different things to be aesthetically pleasing just like we view things like music or poetry. Basically, they're just opinions
