Where possible I try never to explain a piece of my art. It is up to the viewer to take from it what they want to take from it. If it makes them think then that pleases me. If not, if perhaps it just reinforces their own prejudices, then so be it. You can argue or stimulate those with closed minds.
My art comes in two types. The first is where I wish to convey a message or an idea that I believe in and the other is about illustrating a thought or phrase that pops into my head in a serendipitous way that I’ve seemingly not controlled. I may not even agree with the notion I am conveying; sometimes an artist just needs to agitate. Think of it as the equivalent of giving someone a good shake.
The job of the artist should be about amusing and getting people to think. Without thinking we are lost.
