Still my favourite speaker by far is Jordan Peterson, although I really admire Konstantin Kisin as well. His Oxford speech was pretty epic. Both deadly debaters, clear and rational thinkers, and also quite funny when they want to be, which allows the heavy topics they discuss to sink in easier.

@Ben Sherry Yes, definitely. But not only intellectual, well thought out as far as application goes. There are many intellectual speakers who talk about ideas that sound good in theory but are untenable in their application. I love the blend of intellectual with practical. That's really the type of speaker and thinker I'm working to become. What good are ideas if they fall apart the moment they're implemented?
