"I do suspect that material plenty is an incorrect answer to a question that was asked generations ago." And why? We people tried to answer an existential question with an industrial material answer. Sartre's ego-less consciousness, a sailing ship at sea looking for the wind. Sartre's consciousness, his 'Being-For-Itself,' is a Nothingness which catches the breeze of a choice, a project, or a commitment.
A material answer to For-Itself leaves nothing but "more" in its wake until it becomes the absurdity of "Let's go to Mars." At the other extreme "There's paradise after death for the dutiful in a world beyond the heavens." This doesn't feed the children or protect the playground from Leopards.
We were going to talk about Sartre's clash between "Being-For-Itself" and "Being-In-Itself."
Being-in-itself. The Being of inanimate objects. Solid, fixed, mindless object, it's identical with itself, it has no freedom. It just is.
Being-for-itself. The Being of human consciousness. It's not a solid object, it is an empty gap, a Nothingness. And because it has no fixed essence, it is pure freedom, constantly projecting itself into the future.
For Sartre, his "Being-in-the-world" means a being For-itself, a free, hovering consciousness, dropped into a sea of concrete "Being-In-itself" where "Being-For-Itself" is forced to make sense of it all without a safety net.
Our problem as sentient creatures is who trims the sails, who decides and why. As for the sapient let them smoke weed, until then Sartre had his idea of "Project" and Heidegger had his idea of "Resolutness."
Meanwhile, long before Plato the ancients had their Daimōn. Not quite a god, not quite a man. A Priestess once told Socrates that Love was a Great Daimōn, a divine something, a divine what, no one really knew. When Zarathustra went for his Ahura Mazda, to put an end to the quarreling he wanted one source of Wisdom, but far too many minds had wanted to keep their Daimōn, their neither God nor Man, an Aedicule, not good not bad, yet understanding and friendly, fun to be around. Christians, weren't that fond of the semi divine, saw the Daimōn by any other name as a devilish. The Virgin Mary, she's still thought of as an understanding of Daimōn, and she was for Christian Priests, of course different, no devil there.
In the sailing ship terms and where was the captain if not in the interstitial places between God and man, here's Heidegger and Sartre:
Heidegger’s Resoluteness. Heidegger heard the call of his horizon, his captain recognized giveness, the exact build of his wooden ship, he read the specific tides and stars of the waters he was born into, accepting that the ship would eventually sink, he took the wheel with total, quiet authority.
Sartre’s Fundamental Project. Sartre launched his ship into empty spaces, his captain realized the ship has no assigned destination on any map, picking a point on the horizon purely because he decided to, and catching the wind to sail toward it, knowing full well he could turn the wheel hard west tomorrow if he chooses.
Called by history. Making sense of nothingness. Interstitial devious Devils. Take your pick
