Jean-Paul Sarte’s famous quote from Being and Nothingness doesn’t mean what most people think it means.
“Sartre’s point was never that other people make your life hell. He was trying to tinker with the philosophical concept of "being for others,” which holds that people function as mirrors of our psychological understanding of ourselves. Chad the giant douche has been a douche his entire life, but his douchiness is reflected by other people’s reactions to him. The more people he interacts with, the more of his faults he will be forced to recognize via their actions.“
