Henry Hardy and Jennifer Holmes have done a fine job putting together this second volume of Isaiah Berlin's letters, covering the period 1946 to 1960. Apparently, they have published 20-25 percent of the material from this period. That must be about right, because (a) at about 850 pages the volume makes for a pleasant weekend's reading and (b) the weaker letters, of which there are not many, are only just worth including. The editorial material is informative, yet suitably sparse and unobtrusive. There are very few typos in this fat book.
Berlin belongs, with Plato, Leibniz and Hume, to that select group of philosophers one wouldn't mind meeting, were it possible to resurrect them. Of course, Berlin, unlike the other three, was by no means a great philosopher, if indeed he can be called a philosopher at all. What he was, without doubt, was a supremely gifted gossip, able, as Heine was, to gossip well about philosophers, both the living and the dead. He was interested in people and in how ideas made them better, or worse, than they otherwise might have been. He was in fact a connoisseur of personalities and could size one up almost at a glance. Meeting Nixon at a party in 1958, Berlin required no time at all to see what others needed decades to figure out, namely, that Nixon was "a most shifty, vulgar, dishonest and repellent human being." Because Berlin was not a proper philosopher himself, he wasn't much good at assessing the merits of philosophers as philosophers, as opposed to assessing the influence of their ideas on personalities. For example, he judged (at various times) that J.L. Austin was the cleverest man he had ever known (or the second cleverest, after Keynes). But Berlin knew Popper and Russell, and it is pretty easy to see that, in order of increasing cleverness, the correct sequence is Austin, Keynes, Popper and, enjoying a commanding lead, Russell.
These are entertaining letters. They reveal a great deal about the people Berlin knew, if one allows for Berlin's biases. And they reveal even more about Berlin himself, a very odd bird. His interests were confined almost exclusively to personalities. He appears to have been largely blind to the aesthetic qualities of the natural world and, for a clever man alive in a great age of natural science, astonishingly incurious about physical theory. As these letters show, Berlin was very close to his father, whom he claims to have regarded as a younger brother, and deeply attached to that truly outsized personality, Maurice Bowra. What they also show is that, in one respect at least, Berlin was miles beyond most philosophers: his appreciation for the great variety of human personalities enabled him to see that any attempt to press people into a "rational" society is bound to result in a great deal of breakage.
With luck we'll have the next volume of letters in two or three years.
