Post “Post-Truth”: Still a Long Way to Go

Abstract

After recalling the progress made in the diagnosis of the post-truth phenomenon, thanks to recent experimental findings (from cognitive and social psychology) and theoretical work (post-truth versus half-lies and propaganda, degrees in epistemic vice and scale of responsibility), we indicate four other ways to improve our awareness of the scope and mechanisms of post-truth: we introduce some qualifications so as to distinguish between a post-truth world and an Orwellian universe, the negative and positive sides of emotions, an utter contempt for facts, and the sharp dichotomy between facts and values, and between science denialism and blind scientism. Finally, objective truth being taken for granted, we make some suggestions for a “way out”: we should be aware of our cognitive biases and of possible sources of manipulation, cultivate our epistemic virtues, and keep evidence as a prior demand. We should also work in a “scientific spirit,” i.e., refuse any compromise with society, morality, or practice so as to ensure freedom of conscience within an academic and democratic “space of reasons.” But even more urgently, we should avoid some still too frequent misunderstandings about truth itself and about knowledge (which we identify), and remember that post-truth is serious because it is a threat to reality itself: hence we should also take care of our metaphysical prejudices and work to find better ways of ensuring metaphysical knowledge.
