What Is Art?
Art stimulates different parts of our brains with of emotions. Art gives us a way to be creative and express ourselves. You could say "Art is something that makes us more thoughtful and well-rounded humans."
On the other hand, art is such a large part of our everyday lives, we hardly even stop to think about it. Look at the desk or table where you are, right this minute. Someone designed that. It is art. Your shoes are art. Your coffee cup is art. All functional design, well done, is art. So, you could say "Art is something that is both functional and (hopefully) aesthetically pleasing to our eyes."
"Art is in a constant state of change, so nobody can really pin down what it is."
"Art is subjective, and means something different to every single person on earth."
"Art is form and content" means: All art consists of these two things.
-Form means (1) the elements of art, (2) the principles of design and (3) the actual, physical materials that the artist has used. Form, in this context, is concrete and fairly easily described - no matter which piece of art is under scrutiny.
-"Content" is idea-based and means (1) what the artist meant to portray, (2) what the artist actually did portray and (3) how we react, as individuals, to both the intended and actual messages.
-"content" includes ways in which a work was influenced - by religion, or politics, or society in general, or even the artist's use of hallucinogenic substances - at the time it was created. All of these factors, together, make up the "content" side of art.
