Aesthetic is a theme that has been developed by philosophers since time immemorial. Many of those philosopher have tried to conceptualise a universal beauty. Can there be such a concept? A single definition that rules all aesthetics? If beauty were to be immuable, life would be very boring (and architects would be out of job). Beauty is constantly evolving from one era to the next, from one society to the next, from one individual to the next.
What about the ancient temples? Are they not still archetypes of beauty? If there is no single definition of beauty, even in philosophy ; every object that is an “aesthetics of time”‘s archetype can remain beautiful even if the “aesthetic of time” is a variable. That is maybe the nuance between aesthetic and beauty.
