In this book: Plato
Socrates did not write anything. The dialogues of Plato in which his views are primarily represented, and which were cited in note 2, are widely available in translation, perhaps most conveniently in John M. Cooper (ed.), Plato: Complete Works, Hackett, Indianapolis, 1997. But for the Symposium, see also my translation and commentary (Aris & Phillips, Warminster, 1998) which gives what I believe is a proper emphasis to the Socratic elements in the character Socrates' contribution to the occasion.
