This sourcebook, a corrected reprint of the University of South Carolina Press edition of 1972, contains a complete English translation of the sophist material collected in the critical edition of Diels-Krantz, as well as Euthydemus and a completely re-edited Antiphon.
It's hard to read fragments. It's a little like archeology: you have to shift through all these less-than-useful references from other writers, and then, sometimes, you find these absolutely fascinating bits of wisdom and philosophy and it's very exciting when you do. Still, very hard to read indeed.
