Sometimes I learn what I believe in much the same way someone else does, by noticing what I say and do. There may be times when this is my only access to my own thoughts. According to Graham Wallas, 'The little girl had the making of a poet in her who, being told to be sure of her meaning before she spoke, said 'How can I know what I think till I see what I say?' A similar thought was expressed by Robert Motherwell: 'I would say that most good painters don't know what they think until they paint it.'
