Here is the picture of this Old Master: a quiet, awkward, forceful Scotchman, whose philosophy has entered everywhere into the life of politics and become a world-force in thought; an impracticable Commissioner of Customs, who has left for the instruction of statesmen the best theory of taxation; an unbusiness-like professor, who established the science of business; a man of books, who is universally honored by men of action; plain, eccentric, learned, inspired. The things that strike us most about him are, his boldness of conception and wideness of outlook, his breadth and comprehensiveness of treatment, and his carefully clarified and beautified style.
