/ ēˈlisət /
evoke or draw out a response, answer, or fact from someone
To ask what art is good for is not exactly the same as asking what its purpose is. Art does not have to have a purpose. Because the work is its own justification, no further aim or goal is necessarily required to explain or, still less, to justify its existence. To say that art does not have to serve an aim beyond itself, even though it may sometimes do so, is not to say that it is good for nothing. As one of the greatest goods of human experience, it is good for many things.
To me art is one major form of response to the world. It is often an attempt to capture an aspect of the world, to draw attention to something about it, to comment on it, to present a surprising or fresh angle on it, to represent it for the sake of exploring something about it, or enjoying or celebrating it - the simple colors or shapes of an object, its eccentricity or typicality, the interest it provokes.
