> I think Marvin Minsky was the first person that I saw take a stand against "knowing yourself"

  Ordinarily M. de Villefort made and returned very few visits. His wife
  visited for him, and this was the received thing in the world, where
  the weighty and multifarious occupations of the magistrate were
  accepted as an excuse for what was really only calculated pride, a
  manifestation of professed superiority—in fact, the application of the
  axiom, _Pretend to think well of yourself, and the world will think
  well of you_, an axiom a hundred times more useful in society nowadays
  than that of the Greeks, “Know thyself,” a knowledge for which, in our
  days, we have substituted the less difficult and more advantageous
  science of _knowing others_.

Did Dumas explore the liminal space between "know thyself" and "know others", also known as "know one another"?

Did Villefort's wife or "The Count"'s romantic interests help them patch up their blind spots?

One can ofc argue that mutual learning has been the death of many a marriage/family, but I'm more interested in how self-reliance taken to its "rational-agentic-alignment" extreme is a primary obstacle to self-improvement :)

That's a framing Minsky didn't take in his Society of Mind.. but I'm not obviously looking forward to a hallucinated sequel Mind of Society

And, spoiler alert, Villefort is nouveau riche, Mammon-oriented, and has pretensions of philosophy. Where have I seen that before? He is also the villain of the story.
