Nope, not talking about particles or science, but about the minor dialogue by Plato, wherein Socrates interrogates a rhapsode name Ion on his vocation.

Generally, a rhapsode was someone who memorized an epic poem or myth and was an expert on reciting it. Ion specialized in Homer. He says that he also comments on it, but that doesn’t quite track, not in the least because Socrates’ questioning more or less positions as a sort of idiot savant who is able to recite Homer’s epic poems so well because, in the moment, he is divinely inspired. Socrates shows this by arguing that you could only speak well on, to use one Socrates’ example, horsemanship if you were also an expert horseman. He then, rather meanly, shows up Ion as a bit of dolt, which leads Socrates to conclude that Ion is divinely inspired and, by implication, all such performers who reach the highest levels of their profession.
