In that case he seems to not believe in free will. Free will is necessary to choose abstract concepts for their own sake, since as he notes only physical passions can drive us to take involuntary action. At any rate, it seems to be all part of the same package, at least to me. As a side point, I've noticed that pretty much all these cutting edge, modern ideas that we believe have overthrown the ideas of the past were…
> In that case he seems to not believe in free will. Free will is necessary to choose abstract concepts for their own sake, since as he notes only physical passions can drive us to take involuntary action. Hume argues explicitly for free will via compatibilism. The SEP has an excellent summary of the argument[1], but in sum: what matters for moral responsibility is hypothetical liberty. Our ability to will (undispute…
I've seen quite similar concepts to the ones you mention re: Kant, Mill, Descartes, etc in different Platonic dialogues. So, they are maybe micro innovative, but not in a big picture sense.
By "intelligent design" I mean Socrates began his quest looking for a philosopher that could explain the world in terms of 'why' orchestrated by an overarching mind, instead of 'how'. From Phaedo,
"One day I heard someone reading, as he said, from a book of Anaxagoras, and saying that it is Mind that directs and is the cause of everything. I was delighted with this cause and it seemed to me good, in a way, that Mind should be the cause of all. I thought that if this were so, the directing Mind would direct everything and arrange each thing in the way that was best."
Socrates goes on to find out Anaxagoras is blowing smoke, and in general is displeased with the scientism of his day, where everyone explains the world in terms of 'how' instead of 'why'. So, he then goes about questioning all the contemporary philosophers to see if any are able to articulate the kind of explanation he's looking for, and for the most part (except for Diotima) they are unable to give a satisfactory explanation.
