“Rare almost as great poets, rarer, perhaps, than veritable saints and martyrs; are consummate men of business. A man, to be excellent in this way, requires a great knowledge of character, with that exquisite tact which feels unerringly the right moment when to act. A discreet rapidity must pervade all the movements of his thought and action. He must be singularly free from vanity, and is generally found to be an enthusiast who has the art to conceal his enthusiasm.”
