There is a popular picture of Socrates as someone inviting us to think for ourselves. I was just re-reading the Euthyphro, and realizing that the popular picture is severely incomplete.
Recall the setting. Euthyphro is prosecuting a murder case against his father. The case is fraught with complexity and which a typical Greek would think should not be brought for multiple reasons, the main one being that the accused is the prosecutor’s father and we have very strong duties towards parents, and a secondary one being that the killing was unintentional and by neglect. Socrates then says:
most men would not know how they could do this and be right. It is not the part of anyone to do this, but of one who is far advanced in wisdom. (4b)
We learn in the rest of the dialogue that Euthyphro is pompous, full of himself, needs simple distinctions to be explained, and, to understate the point, is far from “advanced in wisdom”. And he thinks for himself, doing that which the ordinary Greek thinks to be a quite bad idea.
The message we get seems to be that you should abide by cultural norms, unless you are “far advanced in wisdom”. And when we add the critiques of cultural elites and ordinary competent craftsmen from the Apology, we see that almost no one is “advanced in wisdom”. The consequence is that we should not depart significantly from cultural norms.
This reading fits well with the general message we get about the poets: they don’t know how to live well, but they have some kind of a connection with the gods, so presumably we should live by their message. Perhaps there is an exception for those sufficiently wise to figure things out for themselves, but those are extremely rare, while those who think themselves wise are extremely common. There is a great risk in significantly departing from the cultural norms enshrined in the poets—for one is much more likely to be one of those who think themselves wise than one of those who are genuinely wise.
I am not endorsing this kind of complacency. For one, those of us who are religious have two rich sets of cultural norms to draw on, a secular set and a religious one, and in our present Western setting the two tend to have sufficient disagreement that complacency is not possible—one must make a choice in many cases. And then there is grace.
