does piety follow the good, or the god? The trajectory of Socratic thought contrasts with traditional Greek theology, which took lex talionis (the eye for an eye principle) for granted. Socrates thought that goodness is independent from gods, and gods must themselves be pious. Socrates affirms a belief in gods in Plato's Apology, where he says to the jurors that he acknowledges gods more than his accusers. For Plato's Socrates, the existence of gods is taken for granted; in none of his dialogues does he probe whether gods exist or not. In Apology, a case for Socrates being agnostic can be made, based on his discussion of the great unknown after death, and in Phaedo (the dialogue with his students in his last day) Socrates gives expression to a clear belief in the immortality of the soul. He also believed in oracles, divinations and other messages from gods. These signs did not offer him any positive belief on moral issues; rather, they were predictions of unfavorable future events. In Xenophon's Memorabilia, Socrates constructs an argument close to the contemporary teleological intelligent-design argument. He claims that since there are many features in the universe that exhibit "signs of forethought" (e.g., eyelids), a divine creator must have created the universe. He then deduces that the creator should be omniscient and omnipotent and also that it created the universe for the advance of humankind, since humans naturally have many abilities that other animals do not. At times, Socrates speaks of a single deity, while at other times he refers to plural "gods". This has been interpreted to mean that he either believed that a supreme deity commanded other gods, or that various gods were parts, or manifestations, of this single deity. It has been a source of puzzlement how Socrates's religious beliefs can be consistent with his strict adherence to rationalism. Philosophy professor Mark McPherran suggests that Socrates interpreted every divine sign through secular rationality for confirmation. Professor of ancient philosophy A. A. Long suggests that it is anachronistic to suppose that Socrates believed the religious and rational realms were separate. Socratic daimonion In several texts (e.g., Plato's Euthyphro 3b5; Apology 31c–d; Xenophon's Memorabilia 1.1.2) Socrates claims he hears a daimōnic sign—an inner voice heard usually when he was about to make a mistake. Socrates gave a brief description of this daimonion at his trial (Apology 31c–d): "...The reason for this is something
