Man is nothing else but that which he makes of himself. That is the first principle of existentialism
Are we "condemned" to be free, as Sartre would seem at first glance to have it, or is such freedom more, as he would perhaps really contend, an opportunity staring us in the face if only we'd pay attention?
However, as his understanding of how social and economic limitations on our freedom to choose increased he began to stop identifying as a pure existentialist and openly declared himself to have always been an anarchist.
A Quartz writer took an interesting and recognisable angle on Sartre, claiming that long before she read him, she had a clear idea of who he was. Or who she thought he was. She knew all about the turtleneck-wearing, chain-cigarette-smoking, moody sort of soul, with a melancholy philosophy to match. After opening his books, though, it became clear to her that this brooding reputation didn’t match the reality. His words didn’t read like those of a poet in crisis, but like something that would not look out of place in a self-help book.
