Mark Helprin

As long as you have life and breath, believe. Believe for those who cannot. Believe even if you have stopped believing. Believe for the sake of the dead, for love, to keep your heart beating, believe. Never give up, never despair, let no mystery confound you into the conclusion that mystery cannot be yours.

The arts community is generally dominated by liberals because if you are concerned mainly with painting or sculpture, you don't have time to study how the world works. And if you have no understanding of economics, strategy, history and politics, then naturally you would be a liberal.
