Although Xenophanes has traditionally been interpreted in terms of the
Eleatics and
Skeptics who were influenced by him and saw him as their predecessor and founder, modern scholarship considers him to be a highly original and distinct philosopher whose philosophy extends well beyond the influence he had on later philosophical schools. As a social critic, Xenophanes composed poems on proper behavior at a
symposium and criticized the cultural glorification of athletes. Xenophanes sought to reform the understanding of
divine nature by casting doubt on Greek mythology as relayed by
Hesiod and
Homer, in order to make it more consistent with notions of piety from
Ancient Greek religion. He formulated natural explanations for phenomena such as the formation of
clouds and
rainbows rather than myths, satirizing traditional religious views of his time as human
projections. As an early thinker in
epistemology, he drew distinctions between the ideas of knowledge and belief as opposed to
truth, which he believed was only possible for the gods.
Social criticism . Xenophanes criticized these drinking parties as they were celebrated in his time for their excesses and failures to honor the gods. Xenophanes wrote a number of elegiac poems on proper conduct at a
symposium, the Ancient Greek drinking parties that were held to commemorate athletic or poetic victories, or to welcome young men into aristocratic society. The surviving fragments stress the importance of piety and honor to the gods, and they discourage drunkenness and intemperance, endorsing moderation and criticism of luxury and excess. Xenophanes rejected the value of athletic victories, stating that cultivating wisdom was more important.
Divine nature Orphism and
Pythagorean philosophy introduced into the Greek spirituality the notions of guilt and pureness, causing a dichotomic belief between the divine soul and the mortal body. This doctrine is in contrast with the traditional religions as espoused by
Homer and
Hesiod. God moves all things, but he is thought to be immobile, characterized by oneness and unicity, eternity, and a spiritual nature which is bodiless and is not anthropomorphic. He has a free will and is the Highest Good, he embodies the beauty of the moral perfection and of the absence of sin. Xenophanes espoused a belief that "
God is one, supreme among gods and men, and not like mortals in body or in mind". He maintained that there was one greatest God. God is one eternal being, spherical in form, comprehending all things within himself, is the absolute
mind and thought, therefore is intelligent, and moves all things, but bears no resemblance to human nature either in body or mind. While Xenophanes rejected Homeric theology, he did not question the presence of a divine entity; rather his philosophy was a critique on Ancient Greek writers and their conception of divinity. Regarding Xenophanes'
positive theology five key concepts about God can be formed. God is: beyond human morality, does not resemble human form, cannot die or be born (God is divine thus eternal), no divine hierarchy exists, and God does not intervene in human affairs.
Natural philosophy . Xenophanes' understanding of divine nature as separate and uninvolved in human affairs motivated him to come up with naturalistic explanations for physical phenomena. Xenophanes was likely the first philosopher to come up with an explanation for the manifestation of
St. Elmo's fire that appears on the masts of ships when they pass through clouds during a thunderstorm. Although the actual phenomenon behind St. Elmo's fire would not be understood until the discovery of static electricity in the modern era, Xenophanes' explanation, which attempted to explain the glow as being caused by agitations of small droplets of clouds, was unique in the ancient world. In Xenophanes' cosmology, there is only one boundary to the universe, the one "seen by our feet". Xenophanes believed that the earth extended infinitely far down, as well as infinitely far in every direction. A consequence of his belief in an infinitely extended earth was that rather than having the sun pass under the earth at sunset, Xenophanes believed that the sun and the moon traveled along a straight line westward, after which point a new sun or moon would be reconstituted after an eclipse. While this potentially infinite series of suns and moons traveling would likely be considered objectionable to modern scientists, this means that Xenophanes understood the sun and moon as a "type" of object that appeared in the sky, rather than a specific individual object that reappeared every new day. Xenophanes concluded from his examination of
fossils of sea creatures that were found above land that water once must have covered all of the Earth's surface. He used this evidence to conclude that the
arche or cosmic principle of the universe was a tide flowing in and out between wet and dry, or earth (γῆ) and water (ὕδωρ). These two extreme states would alternate between one another, and with the alternation human life would become extinct, then regenerate (or vice versa depending on the dominant form). The argument can be considered a rebuke to
Anaximenes' air theory. The idea of alternating states and human life perishing and coming back suggests he believed in the principle of causation, another distinguishing step that Xenophanes takes away from Ancient philosophical traditions to ones based more on scientific observation. This use of
evidence was an important step in advancing from simply stating an idea to backing it up by evidence and observation.
Epistemology Xenophanes is one of the first philosophers to show interest in
epistemological questions as well as metaphysical ones. He held that there actually exists an objective
truth in
reality, but that as mere mortals, humans are
unable to know it. He is credited with being one of the first philosophers to distinguish between
true belief and
knowledge, as well as acknowledge the prospect that one can think he knows something but not really know it. His verses on skepticism are quoted by
Sextus Empiricus as follows: Yet, with regard to the gods and what I declare about all things: No man has seen what is clear nor will any man ever know it. Nay, for even should he chance to affirm what is really existent, He himself knoweth it not; for all is swayed by opining. Due to the lack of whole works by Xenophanes, his views are difficult to interpret, so that the implication of knowing being something deeper ("a clearer truth") may have special implications, or it may mean that you cannot know something just by looking at it. It is known that the most and widest variety of evidence was considered by Xenophanes to be the surest way to prove a theory. == Legacy and influence ==
