In the courts, too, his friends thought him eccentric and singular.
“He had no system, no order; he did not keep a clerk; he had neither library, nor index, nor cash book. When he made notes, he would throw them into a drawer, put them into his vest pocket, or into his hat. … But in the inner man, symmetry and method prevailed. He did not need an orderly office, did not need pen and ink, because his workshop was inside his head.“
