" Along with the terrifying side of this comes a great promise: Sartre’s existentialism implies that it is possible to be authentic and free, as long as you keep up the effort. It is exhilarating to exactly the same degree that it’s frightening, and for the same reasons. As Sartre summed it up in an interview shortly after the lecture: There is no traced-out path to lead man to his salvation; he must constantly invent his own path. But, to invent it, he is free, responsible, without excuse, and every hope lies within him. "
