Plato Euthyphro, Apology, Crito, Phaedo, Phaedrus

a definition accepted by Plato, but not considered complete until the purpose of our service to the gods is determined. How Plato would determine it may be seen in the Apology (30 A), where Socrates says his life has been spent in the endeavour to persuade men to care chiefly for the perfection of their souls. The preceding line "men to care chiefly for the perfection of their souls" is underlined in the manuscript. The Euthyphro may perhaps be regarded as a sort of scientific justification of the position taken in the Apology.

Special editions of the Euthyphro are numerous. Among them those of Schanz (1887), Christ (1890), Adam (1890), and Heidel (1902) may be chosen for especial mention. The last named contains an exhaustive bibliography.
