Monday Night Philosophy remembers the complexities of Columbus Day by investigating the various cultures of the Bay Area's indigenous peoples. Richard Schwartz has searched for, found and recorded hundreds of Native American sites in the Bay Area. The difficult and complex interactions among the different indigenous cultures living in the Bay Area multiplied dramatically with the arrival of the Spanish and was further complicated when the  Gold Rush brought people from all over the world to their home territory. What survives and what has been lost? Schwartz details this complexity, enhancing our appreciation of the human inhabitation of our small piece of paradise over the millennia.
