Remember Marcus from Groundwork for the Metaphysics of MGTOW? @Zwei recommended a channel called
John Vervaeke that has a series of videos called "Awakening from the Meaning Crisis" that gave me some strong Marcus-vibes, and I want to recommend it.
I'm not through the whole series. Only about the first 10 out of 40+ but I've been impressed so far, and since I talk a lot about meaning and purpose, it has been worth my time.
