“Do not merely practice your art, but force your way into its secrets; it deserves that, for only art and science can exalt man to divinity.”

Part I, ch. 1.
The Compleat Angler (1653-1655)

Bill Moyers interview (2002)
Context: I used to say that arts were talked about in the arts and leisure page. Now, why would it be arts and leisure? Why do we think that arts are leisure? Why isn't it arts and science or arts and the most important thing in your life? I think that art has become a big scarlet letter in our culture.
It's a big "A." And it says, you are an elitist, you're effete, or whatever those things... do you know what I mean? It means you don't connect. And I don't believe that. I think we've patronized our audiences long enough.
You can do things that would bring people to another place and still get someone on a very daily mundane moving level but you don't have to separate art from the masses.

Context: If you want to really hurt your parents, and you don't have the nerve to be gay, the least you can do is go into the arts. I'm not kidding. The arts are not a way to make a living. They are a very human way of making life more bearable. Practicing an art, no matter how well or badly, is a way to make your soul grow, for heaven's sake. Sing in the shower. Dance to the radio. Tell stories. Write a poem to a friend, even a lousy poem. Do it as well as you possibly can. You will get an enormous reward. You will have created something.

Context: In this science the illustrations and examples are not confined in their effect merely to the practice they afford in the analytical art, but [... ] they also store the mind with independent geometrical and physical knowledge. Besides, it should be considered, that the only effectual method of impressing abstract formulae and rules upon the memory, and, indeed, of making them fully and clearly apprehended by the understanding, is by examples of their practical application.
