I believe that children are the worlds greatest painters and adult abstract painters strive to emulate the inocence of children. The ability of a abstract painter to produce anything of substance is based on their ability to capture a unbiased view of the world, a painting not influenced by societies needs to catagorize everthing in to recognizable buckets of things thus creating a certain life.
Young children are less influenced by societies insecurities and therefore paint from the spirit, or their essential being. They don't feel the need for acceptance and definition because their environment is safe from criticism. Whatever they produce is accepted.
An great artist lives in a world free of the need of certainty, free of a world that defines everything it sees. We look at the world differently. Our visual experience of the world is more mysterious, our life is an exploration into uncertianty. When we look at the sky we don't see clouds, we see beauty. We are free from this definition of what we are looking at.
