Using the Sokal Hoax as a salutary case, Kramer summarizes how postmodernist philosophers treated truth as a flawed “foundational” concept. These ideas filtered into popular culture as the widespread notion that individual perceptions and emotional responses should outweigh objective measures of truth. In media, emotional opinions typically gain a far greater audience than does reason. Kramer argues that the overvaluing of emotion appears both in the right (Trump’s speeches, neuro-marketing) and in the left (multiple “knowledges,” microaggressions). Nevertheless, evolutionary adaptations ensure that humans will seek truth, and developments such as fact-checking reveal the high value placed on truths that do not depend on individual subjectivity. In regard to “truth,” the postmodern era is not philosophically postmodernist.
