Now let us take up from the beginning the question, what the accusation is from which the false prejudice against me has arisen, in which Meletus trusted when he brought this suit against me. What did those who aroused the prejudice say to arouse it? I must, as it were, read their sworn statement as if they were plaintiffs: “Socrates is a criminal and a busybody, investigating the things beneath the earth and in the heavens and making the weaker argument stronger and teaching others these same things.” Something of that sort it is. For you yourselves saw these things in Aristophanes' comedy...
Plato, Apology, 19a (Emphasis added)
The
good father mentions that Plato was the first to write about sophistry; he doesn't explain why. The reason is that Socrates was put to death over charges of this type. Insofar as Plato is a reliable narrator of Socrates' trial, we see that his accusers didn't try to explain
how he did it, only claiming that he did it (and taught others to do so as well -- 'corrupting the youth of Athens' was the actual charge).
Sophia in ancient Greek means 'wisdom.' One place where the ancient Sophists would have disputed with Father Ripperger was over Ripperger's central claim that they were not concerned with the truth of the claims being disputed. Readers of the Hall are familiar with two of the more famous Sophists, especially Protagoras but also Gorgias. These two did in fact run schools that included rhetoric as a means of obraining and wielding political power. However, neither seem to have thought they were doing something dastardly by doing so. The ancient claim that this is a path of wisdom is not ridiculous.
Rhetoric as a means of obtaining and wielding power is nonviolent, and indeed not even coercive: people agree to go along with the arguments. The charges leveled against Socrates are akin to buyer's remorse, anger after the fact that an argument that was accepted -- 'buy this car!' -- had consequences the buyer later didn't like. The worst thing that can be said about Gorgias and his followers was that they convinced people to go along with things that they later regretted. It might be that power corrupts necessarily, and that any system for seeking and obtaining power is going to be in some sense morally wrong. Contrasted with conquerors like Genghis Khan, however, the Sophists' road to political power looks mild indeed.
As far as 'not caring about the truth,' Protagoras in particular had a claim about the nature of truth that is opposed to the one that Father Ripperger advocates. For the Catholic, there is a God who knows all and whose knowledge entails capital-T Truth about the world. That was not true in ancient Greece, where even the gods could be wrong about things. Protagoras believed, and argued openly, that what the truth is depends on human interpretation, because human minds are the only interpreters of the facts of the world to which we have any easy access. This was normally framed as "man is the measure of all things." It is at least sometimes true. Is it hot today? Today we can look at a thermometer and get an objective reading as to the ambient temperature, but 'whether it is hot' is a human interpretation that obtains regardless of what the thermometer might say. If you feel hot, you are hot.
When we get to politics, which is the sphere in which rhetoric is most significant because rhetoric is the method of politics in democratic societies like ancient Athens, consulting with others turns out to be both important and legitimate. Aristotle didn't write the Rhetoric to advise against the practice, but to discuss how to do it well and how to avoid doing it badly. That is what Gorgias or Protagoras thought he was doing too. For both, success was an important part of the criteria for 'doing it well.'
You can see why on Protagoras' model. If man is the measure of all things, convincing all the men in your society that your view is correct is equivalent to establishing that the view is true. Such truths can then be used as grounds for progress. If we all agree that it's hot today, it is hot and perhaps we can go to the beach to swim. If we all agree that Mexican food would be good for dinner, that's the truth and we can act on it. Soon we shall all have delicious food and margaritas: far better a world than if we spent the evening arguing about where to eat, and never coming to a conclusion!
The charge was unfair pointed at Socrates, Plato suggests, partly because Socrates didn't seek any political power. Partly, too, Socrates was unusually willing to accept that he didn't know what the truth was: he might lead you into an argument in which, to extend the metaphor, you decided that you couldn't agree on dinner and might therefore end up going hungry. This state of confusion about the truth is called
aporia, and Socrates seems to have often sought to convince people not 'of what was true,' but that they really didn't know and should think about it some more. That was where real thinking, and not just rhetoric, began to take place. This transition to deeper and truer thinking, Plato seems to have believed and suggests that Socrates did, was noble.
You can contrast this with the opponents of sophistry, those who accused Socrates and had him executed. Their response to words was to marshal the power of the state to kill off one of its loyal citizens. Socrates' loyalty is
demonstrated in the Crito, where he accepts the punishment rather than defying the state when given the opportunity to escape.* The shift from rhetoric to violence is sharp, and it isn't obvious that the violent are the ones on the right side of it.
Thus, when we are talking about sophistry, we should take some care. If the inquiry helps us identify bad sorts of arguments and avoid them, it is well. If it turns into a sort of dividing of our community that licenses violence against those with whom we disagree, that is the error that ancient Athens made in executing Socrates.
* Xenophon gives a different account, and those two differing accounts are the limit of our sources.
