Socrates wrote nothing, according to our physical sources today of him (none, just none) and his contemporaries (some, although copies of copies to the exponent, of course) -- who do also provide some alleged quotes or portrayals (Aristophanes, Xenophon, Plato).

But all of the non-contemporaries are just writing fan-fiction, and his few extant contemporaries have written him in a style which *coincidentally* ( ) serves their own purposes.

Don't get me wrong, there are a bunch of good aphorisms here...
But the chances that they are actually the output of the historical Socrates, as opposed to the literary one, are slim to nil.
