Plato and Aristotle on Religion

Aristotle’s statements about “god” have sometimes troubled both religious people and non-religious people. For the believers they seem to say too little, and yet for nonbelievers they seem to say too much. But views that generate opposite complaints might be taken to represent a happy medium of sorts. In this troubled world of ours, so full of religious strife, the generous and optimistic spirit of Plato and Aristotle has much to be commended.

I use the lower case “god” to translate Plato and Aristotle’s ho theos, which can also be rendered “the god”. Many have read an incipient monotheism into this term.

In the course of their philosophical work, Plato and Aristotle address many issues relevant to religion, without attaching themselves to any particular creed or orthodoxy. Conventional Greek religion in their day was more concerned with ceremonial observance than with specific belief. Plato nonetheless criticizes the very human foibles attributed to the gods in Greek mythology, and generally rejects argument from authority in favor of shareable reasoning. For Plato, worthiness of the designation “god” implies a virtual identity with the good, the true, and the beautiful. A god would, for example, be incapable of jealousy. Aristotle shares this positive perspective, and does not speak about mythology at all, except in a literary way.

Reception of Plato and Aristotle in the Arabic, Hebrew, and Latin traditions was largely filtered through the complex history of neoplatonism. At the same time, neoplatonism — and especially the work of its founder, Plotinus — greatly influenced later theology. Although Plotinus was nominally a polytheist, his philosophy focuses intensely on the relation of all things to the One. Augustine in his Confessions describes his reading of Plotinus as a halfway point toward his conversion to Christianity. During the Islamic Golden Age, an Arabic paraphrase of Plotinus circulated under the title Theology of Aristotle.

After the Roman Empire became officially Christian, the emperor Julian briefly attempted to overthrow Christianity, while claiming support from the later neoplatonic philosophy of Iamblichus. Iamblichus’ Athenian successor Proclus treats the works of Plato as themselves divinely inspired, while also broadly embracing the polytheisms of all nations. Proclus wrote a Platonic Theology as well as an Elements of Theology, and championed a theological interpretation of Plato’s dialogue Parmenides at great length. The Athenian neoplatonic school was eventually closed by the Christian Roman emperor for its persistent advocacy on behalf of pagan traditions.

The Alexandrian neoplatonic school under Ammonius sought to distance itself from the Athenian school’s advocacy of paganism, while at the same time shifting its curriculum to focus much more on Aristotle rather than Plato. Ammonius’ students included both the Christian John Philoponus and the pagan Simplicius, who between them authored the majority of the surviving Greek commentaries on Aristotle. Without endorsing all the details of either of their work, I find it inspiring that they were able to coexist within the same school.

Religion and politics both need more dialogue and less denunciation of the other. Plato and Aristotle and discussions of their work have much to teach us along these lines.
