I have a rather speculative theory about Aristotle either never partaking in the Eleusinian Mysteries, or him being something like Lucius (as portrayed in Apuleisus's Metamophorphoses), where he goes through the motions of the initiation ceremonies, but is essentially blind to there use or meaning.

I wonder about this because I do not believe there is any firsthand account (or secondhand) of him going through this initiation. This may not seem like much of an oddity to us now but in ancient Athens it is believed the vast majority of the population partook of these initiation ceremonies.

From reading Plato, especially with the Analogy of the Cave, there seems to be more correspondence with what occurred in ancient mysteries, so it appears that Plato did partake (I am unsure of any direct historical evidence for this btw?). A great many people do frame Plato as a bit of a mystic, but I have never heard this kind of rhetoric aimed at Aristotle.

Do you have any evidence to suggest that Aristotle went through the Eleusinian Mystery ceremonies?
