Oedipus the Scientist

We’ve been doing “ways of knowing” in my class at Michigan State, and I’ve been resisting the temptation to drag my undergraduates through a tangent on Sophocles. Blog readers are not so lucky. You’ll recall Sophocles’ play about King Oedipus from your freshman class on world literature. The plot gets rolling because Creon, his brother-in-law and some-time rival is back from Delphi with the news that Thebes suffers because the murderer of former King Laius remains unidentified and unpunished. In true macho fashion, Oedipus immediately sets out to discover the facts of the matter, promising swift action upon learning who the culprit is.

The events of the play all pivot from this point, as a series of witnesses are called before Oedipus to give testimony that will allow him to gain knowledge about this crucial unknown fact. I wonder if anyone who read Sophocles’ play or saw it performed was really in suspense about the final outcome. Most of us know that Oedipus himself is the culprit, that in fact Laius was his natural father and that he has married his own mother Jocasta and fathered children with her in the course of assuming the throne of Thebes. I don’t actually think that discovering all these gory details is actually what the play was about. Even Sophocles original audiences would have known the outline of this story from an earlier cycle of plays by Aeschylus.

Sigmund Freud drew a well-known set of psycho-sexual inferences from Oedipus the King, but in accord with ways of knowing I’d like to point out that all of the witnesses called to give testimony to Oedipus in his quest for the truth are reluctant to do so. First Tiresias the prophet of Apollo, then Jocasta herself and finally the shepherd and former servant of Jocasta resist Oedipus’s prodding, each telling him that he and Thebes will be better off if Oedipus gives up his quest for this particular matter of fact. Much earlier Creon has told Oedipus that facts must be seen in light of the motivations that people have for seeking or stating them. Oedipus’s witnesses are compelled to speak a truth they know will serve no good purpose under pain of death.

What, you may reasonably ask, could all this have to do with food (food being the nominal topic of the Thornapple Blog, after all)? I’d like to suggest that we’ve structured our public policy and our scientific research around food from Oedipus’s perspective: a quest for facts of the matter that is divorced from larger and more fundamental commitments to our own good, and that of those around us. It may not be as profound or tragic as Oedipus’s forbidden knowledge, but is it really helpful to ascertain and enforce an objective standard for the allowable amount of rat feces in our oatmeal? Mightn’t it have been more sociable to rest content with a warranted belief that actors along the cereal supply chain are doing all that they can to keep the Avena sativa and the genus Rattus separate from one another?

An oedipal type of knowing invites a rather uncaring and unbonded form of relationship building. To wit, why not blend an especially clean batch of oats with one that exceeds the allowable ratio of contamination so that the new batch is below the threshold? If there’s no evidence that GMOs, high fructose corn sweeteners or preservatives will harm you, why worry about whether people want them in their food? If the EPA standard for lead in drinking water gives you a year to fix the problem, why do anything now? All of these practices are consistent with the fact of the matter, aren’t they?

Oedipus was a little bit too confident that knowing who killed Laius would put him in a position to fix things in Thebes, and those of us in academe may share an overweening faith in a similar kind of facticity. In fact, we’ve set up all of our incentive structures to filter out our loyalties to other human beings (not to mention other species). Perhaps Tiresias and Jocasta were right to insist that those who search for facts would sometimes be wise to temper their quest and look to that which achieves a larger good.
