It is really impossible to say anything worth saying about Plato in general within the limits of a single article. Indeed, the more one studies Plato the more impossible does it become—if the concept of degrees of impossibility may be used in a philosophical journal. The reasons for this are manifold. The first lies in the supreme greatness of Plato as a thinker. Hardly anyone who has made a serious effort to study Plato has escaped receiving the impression of him as probably the greatest thinker of all ages. The difficulty is intensified by the particular form in which his greatness is conveyed to us. One may make a distinction, a relative distinction at least, between different philosophers in this respect. With some, their message is conveyed to us with comparative rapidity, even perhaps on the first careful reading, and subsequent study adds little except in the way of detail. Among these it would perhaps not be unfair to place Hume. Others, on first reading, will appear obscure and difficult, sometimes even repellent. It is only after a much more careful study that their real greatness emerges, and they may go on increasing in stature at every subsequent reading. Such, I believe, to be the experience of the majority of readers with Kant. Plato is almost unique in that he makes his impression in both ways. Almost everyone is captivated by him at first reading, but it is only to those who take the trouble of reading him again and again with the intellectual effort that he himself would have demanded
