Plato’s dialogue Gorgias is mostly about the difference between content and form. Or rather it’s about how Socrates saw the difference between philosophy – content and truth – and rhetoric – form and words. Both of which are practiced and studied today in much different forms from what they were in ancient Greece. But the essential core of his argument is still there for us.
Socrates felt rhetoric – oratory – was shallow; merely using words for persuasion, for effect, for emotion: it lacked the validity, the meaning and depth of philosophy. It lacked truth and knowledge.
If you look at the dichotomy in Gorgias as one between science, fact and evidence on one side, and pseudoscience, conspiracy theories and angry bloggers on the other, then it makes sense in a modern way. Instead of the speeches he discusses, imagine them like this: as blog posts. Gorgias argues his speeches are about freedom – angry bloggers often argue their posts are a right, and they have freedom to write whatever they please, to belittle and demean others without punishment. A modern Socrates might label these sophists “A” types.
What kind of change, then, does rhetoric effect in the soul? Socrates infers from Gorgias that it is persuasion. What kind of persuasion? One kind of persuasion “provides belief without knowing,” and another “provides knowledge.” Clearly knowledge is better than true belief, which is better than false belief, and more knowledge is better than less knowledge. But rhetoric merely imparts belief, Gorgias admits, and experience shows that rhetoric produces both true belief and false belief (454e). By this reasoning rhetoric, to the extent that it is a theoretic art, is powerless to effect the best possible change (knowledge) in the soul of the hearer, but it has the power to effect the worst possible change (false belief) in the hearer’s soul.
This may be the main reason that Socrates stops discussing the greatest of goods and begins to discuss the greatest of evils. It is important to protect one’s soul against the worst effects of rhetoric. Socrates refers to the greatest of evils, in slightly different formulations, over a dozen times. The subject matter of the greatest evil takes many forms, most notably that of injustice. Can the state of soul called false belief be reconciled with the state of soul called injustice?
One could easily apply Socrates’ views about content versus empty form to the local political scene: the debate between financial facts, facility facts and council accomplishments versus the fictions, fantasies and outright lies presented in attack ads, on social media and angry blog posts. Wikipedia tells us:
Socrates believes there are two types: “…one part of it would be flattery, I suppose, and shameful public harangue, while the other—that of getting the souls of the citizens to be as good as possible and of striving valiantly to say what is best, whether the audience will find it more pleasant or more unpleasant—is something admirable. But you’ve never seen this type of oratory…” (502e). Although rhetoric has the potential to be used justly, Socrates believes that in practice, rhetoric is flattery; the rhetorician makes the audience feel worthy because they can identify with the rhetorician’s argument.
