Humans are curious creatures who seek out knowledge about every aspect of the world. We also value knowledge to a great degree. Having a good education is very well-perceived and is a priority of many parents. We sometimes take pride in possessing knowledge, and tend to feel embarrassed when our ignorance gets put on display. More fundamentally, many of our social interactions require tracking what others know and signaling what we ourselves know. For instance, discussing politics with a foreigner might require extra care, as our knowledge of social and economic issues might be specialized relative to the contexts in which we grew up. If I learn that my interlocutor knows as much as I do about the political landscape of my home country, the interaction will likely become a lot more fluid. There is more common ground between us. What is knowledge such that it can play this role in conversation? What underlies our obsession with it? How do we develop the capacity to attribute knowledge to others and to understand them?
