Hey you guys! This is a very good talk about language as a piece of “social technology“ for enhancing the benefits of cooperation, for reaching agreements, for striking deals and for coordinating our activities. Biologist Mark Pagel adds that not having language is like a bird without wings. Wings allow birds to exploit, as well as language opens up the sphere of cooperation for humans to exploit. He says that once we have language, we can put our ideas together and cooperate to have a prosperity that we couldn’t have before we acquired it. But he also suggests that different languages impose a barrier to cooperation and that our modern world now is confronting us with the dilemma: One world. One language?
