Post-truth is pre-fascism, and Trump has been our post-truth president. When we give up on truth, we concede power to those with the wealth and charisma to create spectacle in its place. Without agreement about some basic facts, citizens cannot form the civil society that would allow them to defend themselves. If we lose the institutions that produce facts that are pertinent to us, then we tend to wallow in attractive abstractions and fictions. Truth defends itself particularly poorly when there is not very much of it around, and the era of Trump — like the era of Vladimir Putin in Russia — is one of the decline of local news. Social media is no substitute: It supercharges the mental habits by which we seek emotional stimulation and comfort, which means losing the distinction between what feels true and what actually is true.
Post-truth wears away the rule of law and invites a regime of myth.
