Matt Ridley presents what I believe is a compelling argument for global connectedness, understanding, and cooperation. Especially as the global population of humanity grows, we no longer can afford the “luxury” of isolationism, war, and religious bigotry. At a level beyond, yet including the physical, sex makes great sense. Beyond pleasurable, it’s necessary. I really like Matt’s idea about the sex of ideas and how that specific sexual revolution has led humanity to where it is today – and will lead us into a hopefully brighter future. Yes, maybe it’s time for more sex!
