This great artist is a man whose life-time is consumed by struggle : partly against material circumstances, partly against incomprehension, partly against himself... ... In no other culture has the artist been thought of in this way. Why then in this culture? We have already referred to the exigencies of the open art market. But the struggle was not only to live. Each time a painter realized that he was dissatisfied with the limited role of painting as a celebration of material property and of the status that accompanied it, he inevitably found himself struggling with the very language of his own art as understood by the tradition of his calling. ... ... Every exceptional work was the result of a prolonged successful struggle. Innumerable works involved no struggle. There were also prolonged yet unsuccessful struggles. (P.104)
