Vincent, too, was at his wits' end, and after a long period of solitary soul-searching in the Borinage he decided to follow Theo's advice and become an artist. His earlier desire to help his fellowman as an evangelist gradually developed into an urge, as he later wrote, to leave mankind "some memento in the form of drawings or paintings-not made to please any particular movement, but to express a sincere human feeling."
His parents could not go along with this latest change of course, and the financial responsibility for Vincent passed to his brother Theo, who was now working in the Paris gallery of Boussod, Valadon et Cie., the successors to Goupil's. It was because of Theo.'s loyal support that Van Gogh later came to regard his oeuvre as the fruits of his brother's efforts on his behalf. A lengthy correspondence between the two brothers (which began in August 1872) would continue until the last days of Vincent's life.
