Essential to understanding Trump is his attempt to subject the public to his own solipsistic reality—and thereby destroy our shared basis for democracy.
“An important way to understand Trump and Trumpism is as an assault on reality. At issue is the attempt to control, to own, immediate truth along with any part of history that feeds such truth. Since this behavior stems from Trump’s own mind, it is generally attributed to his narcissism (and he has plenty of that). But I would suggest that the more appropriate term is solipsistic reality. Narcissism suggests self-love and even, in quaint early psychoanalytic language, libido directed at the self. Solipsism has more to do with a cognitive process of interpreting the world exclusively through the experience and needs of the self.“
