"Does this man deserve a niche in the academic hall of fame? I doubt that very much. His thinking is certainly sharp, quick and broad in superficial extension, but it lacks depth, flexibility and above all vision. Nor is it really inquisitive, or at least it hasn’t been since the mid-sixties. From that period on, we see a man who digs in his intellectual heels and defends his fort, warding off ideas that might widen his perspective or make him look at things from a different, perhaps more promising, angle. We see a man who, having made a very promising start, rapidly began to abuse the enormous amount of social power he had acquired, eliminating dissidents while putting up an innocent face to the outside world. A man who professes high ideals of freedom and dignity in his political writings but practises the opposite in his academic activities. We see a compulsive prima donna, a clever manipulator of public opinion, a man who has consistently put his own person above the ideals that all unusually gifted persons occupying a leading position in any sphere of life have a special duty to pursue."
