Who is this guy? I’ve seen a few other links to videos of him flying into outer space on other topics posted on HN recently. I just went and read a bit of his Wikipedia page, so I see he’s a philosopher, but I don’t know what the abstract terms materialism and Hegelian idealism and Lancanian psychoanalysis mean. Is there a less abstract way to understand his position, or important philosophical contributions he’s made that would help me understand him or his ideas on love?
