"In the last letter which he [Vincent] wrote me and which dates from some four days before his death, it says, "I try to do as well as certain painters whom I have greatly loved and admired." People should realize that he was a great artist, something which often coincides with being a great human being. In the course of time this will surely be acknowledged, and many will regret his early death. He himself wanted to die, when I sat at his bedside and said that we would try to get him better and that we hoped that he would then be spared this kind of despair, he said, "La tristesse durera toujours" [The sadness will last forever]. I understood what he wanted to say with those words."
