The Trump White House's preference for loyalty and ideological lock-step over knowledge is on display throughout the administration. Unqualified judg… - Michiko Kakutani

At the same time, Trump continued his personal assault on the English language. Trump’s incoherence (his twisted syntax, his reversals, his insincerity, his bad faith, and his inflammatory bombast) is both emblematic of the chaos he creates and thrives on as well as an essential instrument in his liar’s tool kit. His interviews, off-teleprompter speeches, and tweets are a startling jumble of insults, exclamations, boasts, digressions, non sequiturs, qualifications, exhortations, and innuendos — a bully’s efforts to intimidate, gaslight, polarize, and scapegoat. Precise words, like facts, mean little to Trump, as interpreters, who struggle to translate his grammatical anarchy, can attest.

In his 2007 book, The Cult of the Amateur, the Silicon Valley entrepreneur Andrew Keen warned that the internet not only had democratized information beyond people’s wildest imaginings but also was replacing genuine knowledge with “the wisdom of the crowd,” dangerously blurring the lines between fact and opinion, informed argument and blustering speculation.

Trump often seems like a one-man set of Aesop-like fables — with easy-to-decipher morals like “those who lie down with dogs will get up with fleas” or “when someone tells you who he is, believe him” — but because he is president of the United States, his actions do not simply end in a tagline moral; rather, they ripple outward like a toxic tsunami, creating havoc in the lives of millions. Once he has left office, the damage he has done to American institutions and the country’s foreign policy will take years to repair. And to the degree that his election was a reflection of larger dynamics in society — from the growing partisanship in politics, to the profusion of fake stories on social media, to our isolation in filter bubbles — his departure from the scene will not restore truth to health and well-being, at least not right away.
