It has been my understanding that most of the great artists are and were ..... challenged and tormented in various ways. Some might say it is a requirement to gain true perspective. It seems to me that there are two schools of thought when it comes to art, those who can accept a piece of art and its expression for what it is regardless of its style, and those with money that have no real clue or appreciation. Is it perhaps the latter that were so frustrating to Van Gogh?
