A good study of Socrates by the historian Paul Johnson. Since the subtitle was "A Man for Our Times", I was expecting more concerning the contemporary relevance of Socrates, but this is a simply a straightforward study of Socrates and Socratic philosophy. To the extent that Socrates is a man for all times - and he is - then naturally he is a man for our times.
I prefer the older book on Socrates by Romano Guardini, as Guardini is more philosophically sophisticated than Johnson. I think Johnson is also a little hard on Plato, but Johnson is still excellent.
