Taking stock of our fragmented political landscape, Michael Patrick Lynch delivers a trenchant philosophical take on digital culture and its tendency to make us into dogmatic know-it-alls. The internet - where most shared news stories are not even read by the person posting them - has contributed to the rampant spread of "intellectual arrogance". In this culture, we have come to think that we have nothing to learn from one another; we are rewarded for emotional outrage over reflective thought; and we glorify a defensive rejection of those different from us. Interweaving the works of classic philosophers such as Hannah Arendt and Bertrand Russell and imposing them on a cybernetic future they could not have possibly even imagined, Lynch delves deeply into three core ideas that explain how we've gotten to the way we are: our natural tendency to be overconfident in our knowledge; the tribal politics that feed off our tendency; and the way the outrage factory of social media spreads those politics of arrogance and blind conviction. In addition to identifying an ascendant "know-it-all-ism" in our culture, Lynch offers practical solutions for how we might start reversing this dangerous trend.
