Abstract means literally to draw from or separate. In this sense every artist is abstract for he must create his own work from his visual impressions. A realistic or non-objective approach makes no difference. The result is what counts.
Richard DiebenkornWhen I am halfway there with a painting, it can occasionally be thrilling... But it happens very rarely; usually it's agony... I go to great pains to mask the agony. But the struggle is there. It's the invisible enemy.
