the expression in the art

I think that a subject important is the expression. I refer anyway of expression. The art seems a way for expressing.

The art has a series of definitions about what is. I understand it like a way to express any matter, from expressing feelings  or critiques of any type until expressing new matter that do not exist in our culture. Talking of art remember me a movie, "Teorema" of Pier Paolo Pasollini. In this movie, a character wants to be an artist, but his family obliges him to study other discipline. For events in the movie, this character leave his family and house, bourgeois house, and begin to live in other neighborhood, alone, living his obsession. His art, in the movie, made me sense of way perceptive. I don't know why, but his art like me. While and then of the movie I though, the art is a way to express anymatter. So, the art is a way life, a way that include to language. Art would be a synonymous of to express. I think that in our culture exist the word "art" for the principles of our culture, principles like "specialism", "objectivism", etc. Then the word "art" would be used to talk about social expressions. The art is definite by the tradition of our culture like the study of the aesthetics, in other words, the study of the perceptive, but why the art is not o do not deal with about the cooking or the playing. I think that this is for the dichotomy social and individual of our culture, I do not agree with this. I think that the perceptive, the art, is in our daily life, in our expressions...
