The term aesthetics comes under value theory and it studies sensory-emotional values. Aesthetics has close association with the philosophy of art.

The term came from a Greek word 'aisthetike' and it was first given by Alexander Gottlieb Baumgarten in the year 1735. The term meant 'the science of knowing things via the senses'. The term started to be in use in English in the 19th century.

Aesthetics studies what makes something so very beautiful and some of the things disgusting. It is all based on our sensory judgment that we discriminate between things.

Experts believe that there are so many factors guiding our senses. If we take the example of disgust, cultural issue plays a vital role in terming things as disgusting or not. When we see a stripe of soup on a man's beard, we find it quite repulsive, but the same soup when we see in a bowl, we admire it.
