Richard Crossman ... has a gift, which is useful to teaching but fatal to politics, uncontrolled imagination. There is no side of an argument that he cannot see, and he can well argue that black is white. Once his mind starts working it runs away with him, and he is able to persuade himself of the truth of what he wants to hear. At the same time, with the arrogance of the intellectual, he suggests that anyone who disagrees with him is little more than an idiot.
