"Whatever the final verdict on the General Theory, Keynes' greatness as an economist will not be questioned. His mental capacities had a far wider range than those usually found in professional economists. He was a logician, a great prose writer, a deep psychologist, a bibliophile, an esteemed connoisseur of painting; he had practical gifts of persuasion, political finesse, businesslike efficiency; he had personal gifts which made him have profound influence on those who came into direct contact with him."
