Plato’s Euthyphro is centered around Socrates’ attempts to examine and define the concept of piety. In the course of conversation, he develops a central and somewhat scandalous argument: what is holy is not the same as what the gods do or approve. In fact, the gods ‘sin’ and engage in immoral behavior a lot – they murder, steal, cheat, wage wars, and act out of spite.
Socrates often pointed out how Greece’s most beloved poets – Homer and Hesiod – depicted the gods as all too human, but the first ancient Greek thinker to make radical claims about this matter was Xenophanes of Colophon.
Although appearance of the first philosophers in ancient Greece was all about the emergence of unconventional and nontraditional ways of thinking, Xenophanes could still be justifiably viewed as one of the most – if not the most – unorthodox and even scandalous figure of his era.
There were two things an ancient Greek would never doubt: first, that the gods are in charge of everything and everyone, and second, that we know this because they themselves disclosed it to us. The sun, rainbows, and the very earth we are walking on were believed to be gods and goddesses. Every natural phenomenon was ascribed to some property of a deity; every historical event and fate of an individual race or man was explained as the result of the will of the Olympians.

And how did they know? Muses told them so. Invocation of the Muses served as a traditional and commonplace poetic tool: when a poet wanted to authenticate the truth of his claims, he called on Muses so they would act as witnesses and provide assertion.
This is how Homer opens both of his epic poems: he addresses divine agency. It should not be hard to guess that the ancient Greeks were not very fond of people who dared to doubt their undoubtable beliefs – think of the trials of Socrates or Anaxagoras – and unfortunately, this is exactly what philosophers tend to do.
The first thing the first philosophers did was ask for well-grounded, sound arguments for every claim. Appealing to divine authority did not strike them as a very compelling argument. However, some of the early Greek philosophers still partly accepted conventional religious teachings and even referred to the divine authority.
Socrates' Death

Anaximenes, for example, allegedly said that there are gods, exactly as Greek religion acknowledged, but that they come from air (his Cosmic principle) as well as the rest of the universe. And Parmenides, one of the most ahead-of-his-time thinkers, begins his poem by depicting a divine revelation.
So most of early philosophers did not entirely give up on the traditional gods and divination, but threw down a challenge to the conventional notion of the divine. As Cicero states, Xenophanes was the only one among the most ancient philosophers who, while basing his whole philosophy on the existence of the divine entity, launched a direct attack on the popular religion and “did away with divination from its very foundation.”
Xenophanes was an itinerant poet and philosopher from a small Ionian town of Colophon. He is reported to have had quite a storm-tossed life as he was banished from his homeland, was sold into slavery, and buried his sons with his own hands.

Despite his manifold interests, he is primarily remembered for his critique of traditional religious concepts, and as professor Peter Adamson aptly words it, “in doing so, he inaugurated a not-always-friendly rivalry between Greek religion and Greek philosophy that will persist right through Plato and Aristotle”.
Xenophanes found the traditional understanding of the divine to be inherently flawed and he chiefly blamed Homer and Hesiod for disseminating these widely accepted misconceptions. He writes,
“Both Homer and Hesiod have ascribed to the gods all deeds which among men are matters of reproach and blame: thieving, adultery, and deceiving one another” (Sextus Empiricus, Against the Mathematicians 9.193)

And indeed, it seems like the Greeks imagined their gods in their own image: the gods were born, wore clothes, ate, indulged themselves with sexual adventures, and looked like men, just much more beautiful and perfect. Realizing this, Xenophanes observes:
“If horses had hands, or oxen or lions, or if they could draw with their hands and produce works as men do, then horses would draw figures of gods like horses, and oxen like oxen, and each would render the bodies to be of the same frame that each of them have.” (Clement, Miscellanies 5.110;).
The point is that humans have a tendency to attribute their own characteristics to the divine entities; in other words, humans think of their gods as all too human. Xenophanes believed it was disrespectful to the gods to conceptualize them as being subject to human weaknesses and illicit acts. It is the same as ascribing imperfections to the perfect being – which, without doubt, does not make any sense.

The writings of Xenophanes are not limited to such criticism, he also offered a pretty systematic account of divine nature, which attracts special interest for its unique and ground-breaking perspective. How likely is it of a man from 6th century BC to develop ideas highly similar to the monotheistic understanding of the Christian god? Amidst the classical polytheistic convictions of his society, whose gods are born, have bodies, and resemble men, Xenophanes formed the notion of a god
“greatest among gods and men, not at all like mortals in body or in thought.” (Clement, Miscellanies, 5.109;).
Even though the reference to the “gods” in plural raises a question about whether Xenophanes was a monotheist or polytheist (some scholars even designate him as a pantheist), it is certain that Xenophanean image of the god is set apart from traditional polytheistic convictions and falls on the spectrum of the monotheistic paradigm.

It is more likely that he means lesser deities in the plural form of “gods”. Throughout the records of Xenophanes, only one god, a single divine entity, is presented as the perfect, almighty being who holds sway over the whole universe.
“. . whole [he] sees, whole [he] thinks, and whole [he] hears. . . (Sextus Empiricus, Against the Mathematicians 9.144;).
“Always [he] remains in the same [state], changing not at all, nor is it fitting that [he] come and go to different places at different times. . . but completely without toil [he] agitates all things by the will of his mind.” (Simplicius, Commentary on Aristotle’s Physics 23.10; 23.19;).
All of the characteristics Xenophanes ascribes to the god – omnipresence, omniscience, omnipotence, immobility, incorporeality (spirituality) – are the typical attributes of a monotheistic deity. He prefigured the ideas which still lay centuries ahead.

Another key aspect of Xenophanes’ philosophy is his remarkable contribution to epistemology (the theory of knowledge). He opposes the traditional understanding of divination by claiming that,
“by no means did the gods intimate all things to mortals from the beginning, but in time, inquiring, they discover better.” (Stobaeus, Selections 1.8.2;).
Xenophanes suggests that it is unreasonable of men to expect divine disclosure about the things they seek to know. Moreover, he raises questions about the nature and possibility of sure and certain knowledge. There he makes a fundamental distinction between knowledge and belief/opinion, a theme which will be later taken up, for instance, by Heraclitus, Plato, and Aristotle, and is one of the most important problems in philosophy as a whole.
“…and of course the clear and certain truth no man has seen. Nor will there be anyone who knows about the gods and what I say about all things. For even if, in the best case, one happened to speak just of what has been brought to pass, still he himself would not know. But opinion is allotted to all.” (Sextus Empiricus, Against the Mathematicians 7.49.110;).
Plato's Cave

Plato’s Allegory of the Cave by Jan Saenredam, according to Cornelis van Haarlem, 1604, Albertina, Vienna. Plato’s allegory of the cave, told to us in the Republic, is a thought experiment that is used to this day to illustrate the limits of our knowledge about the world as it is in itself.

It is important to note that by this, Xenophanes does not necessarily reject the possibility of any kind of knowledge, but rather reproves dogmatism and acknowledges boundaries of the dimension of human knowledge. Even though our epistemic status is limited, we can still form opinions and inquire about things. As F.R. Pickering notes,
“Xenophanes is a natural epistemologist, who claims that statements concerning the non-evident realm of the divine as well as the far-reaching generalizations of natural sciences cannot be known with certainty but must remain the objects of opinion.”
Ancient Greeks, on the one hand, had poets who provided answers for all of their questions and, on the other hand, had a poet philosopher who tried to awaken them from their ´dogmatic slumber´ by casting doubts on their answers and asking questions, the relevance of which would persist for centuries to come.
