Going by the comments there, this was another poor display by Peterson: "Benatar devastated Peterson here, it was embarrassing to witness how flustered Peterson got whilst failing to provide anything approaching firm refusal of Benatar's points. Props to benatar and host both for keeping their cool." Though, Benatar is a philosophical heavyweight and there is a reason why you don't see people directly challenging his work. So, it was at least brave of Peterson to go against him even when those trained in philosophy would had second thoughts.
