John Vervaeke has become one of the most well-known voices in cognitive science outside academia. In his YouTube lecture series Awakening from the Meaning Crisis, he takes a historical, philosophical, and cognitive science perspective on human evolution. In the video below he talks about why love matters to the meaning of life. This video is classic Vervaeke (from 2014), but it is perhaps to best introduction to the man and his message of any video out there. Enjoy.
