Art is a form of expression on the part of an individual that provokes thought or emotion of any kind.
Art is necessary for so many reasons. One of my favorite movies is Dead Poet's Society, in which Professor Keating remarks, "We read and write poetry because we are members of the human race and the human race is filled with passion; medicine, law, business, engineering, these are noble pursuits, and necessary to sustain life. But poetry, beauty, romance, love, these are what we stay alive for." This phrase doesn't just apply to poetry but also to art of all kinds. Art is a mirror of humanity, a social commentary that is widely accepted even when it is controversial. It is a way for an artist to make a statement, to use their voice and a way for people to feed their intellectual soul. A world without art would be a bland one in which the human race is completely quelled. Not only is there no way for anyone to express themselves, but in a world where there is no art, there would be no DESIRE to express oneself, or any desire to find meaning.
