In the wilds of planet Earth, there exists a species so creative that it not only uses tools but is constantly rewriting the rules of what a tool can be, so cooperative that they build wildly complex systems to support each other and so consternating that its inconsistent behavior would make even the most seasoned of biologists screamed. That species is of course: human beings. This session will explore all the beauty and bizarreness that is us.
