This is a lecture series from John Vervaeke, a professor at the University of Toronto. It is very much a grand theory on how humans evolved to create meaning, why people seek it, and why there is a decline of meaning in modern society. The first lecture starts by outlining the evolutionary origins of rituals from Paleolithic times. I found it absolutely compelling and couldn't stop listening, so I thought I would share. If you like Robert Sapolsky you will, probably like this.
