In my opinion, we can’t evaluate beauty objectively. This is the main reason why
people evaluate art subjectively. It is because our appreciation or admiration of art is
largely concerned with our perception of beauty. Just like in the saying that “Beauty is in
the eye of the beholder”, one’s own perception and definition of beauty may differ from
others. How we see art as beautiful does not only mean by how we see it through our
naked eye. It also depends on our emotional attachment to the art and what impact the art
has on us.

Pragmatism or Practicalism. A thing or idea is beautiful if it satisfies a practical need or
purpose to one's life. For instance, a statue is beautiful because it helps attract tourists to
the area.

Existentialism. A thing or idea is beautiful if it has a purpose or can give meaning in
one's life. A mother, for example, saw a drawing on the fridge by her son and thought of
it as beautiful because it means a lot to her.

Realism. A thing or idea has an existence, meaning, purpose, and beauty that is
independent of an individual's views on it. An example of this is a flower that has its own
beauty that is independent from how others may see it as.

Idealism. A thing or idea is beautiful only if it reaches a pre-conceived standard of
beauty or perfection. A sculpture for instance is beautiful because it has the perfect
proportions.

Naturalism. A thing or idea is beautiful if it was already previously experienced and
established to be beautiful. A sunset over the ocean is beautiful because it has always
been known to be beautiful.
