What is Art?

My sister sent me this video with the question:  What is art? And what does our art say about us?

So, what is art?  For something I spend a lot of time on, I haven't spent much time defining it.  It's something I love making and enjoy seeing.  My niece loved it because it was one place that had no rules.    Those simple things have been enough.

But when the question is asked, I have to wonder...what is it for?  Is it really just one thing or is it many things to many people?

And all sorts of people have weighed in on it...

The Betrothed and Eiffel Tower, 1913

Mark Chagall: Art is the unceasing effort to compete with the beauty of flowers – and never succeeding.

Ayn Rand: Art is a selective re-creation of reality according to an artist’s metaphysical value-judgments.

Georgia O'Keeffe: Filling a space in a beautiful way. That's what art means to me.

Robert Frost: To me the thing that art does for life is to clean it – to strip it to form.

Jacques-Louis David: To give a body and a perfect form to one’s thought, this—and only this—is to be an artist.

Aristotle: The aim of art is to represent not the outward appearance of things, but their inward significance.

With all that being said...what is art?  What is it for to you?
