Aesthetics is the study of beauty. That might sound funny, but any interior designer or art gallery patron has a thing or two to say about aesthetics.
The philosopher, Alexander Baumgarten, gave us our current meaning of aesthetics. In the mid-1700s, he used the word to describe artistic beauty with the added bonus of a value judgment of good or bad taste. The public embraced Baumgarten's usage, and fashion mavens and art critics got a new word to describe the marriage of beauty and taste.
