Good post @chbartist. Art is the expression of our thoughts, feelings and emotions, every stimulus that goes to one of our 5 senses and that makes us experience that externalization of the other. But it is not only to transmit or receive ideas and feelings, but to do it with grace.
To conclude my speech, I believe that the importance of art lies in the applicability that we give to our life, as a form of expression of our deepest feelings, the externalization of being.
