Phaedo

Ph do or Phaedo also known to ancient readers as On The Soul, is one of the best-known dialogues of Plato's middle period, along with the Republic and the Symposium. The philosophical subject of the dialogue is the immortality of the soul. It is set in the last hours prior to the death of Socrates, and is Plato's fourth and last dialogue to detail the philosopher's final days, following Euthyphro, Apology, and Crito. For its moving account of the execution of Socrates, the Phaedo ranks among the supreme literary achievements of antiquity. It is also a seminal document for many ideas deeply ingrained in western culture, and provides one of the best introductions to Plato's thought.
