Plato’s Euthyphro [EPUB ebook] 

In Euthyphro, Socrates is on his way to the court where he must defend himself against serious charges brought by religious and political authorities. On the way, he meets Euthyphro, an expert on religious matters, who has come to prosecute his own father. Socrates questions Euthyphro’s claim that religion serves as the basis for ethics. –
