Existentialism and Human Emotions by Jean-Paul Sartre: Man is nothing else but what he makes of himself… But what do we mean by this, if not that man has a greater dignity than a stone or table? … Rather than a patch of moss, a piece of garbage, or a cauliflower… man will be what he will have planned to be. Not what he will want to be. Because by the word “will” we generally mean a conscious decision, which is subsequent to what we have already made of ourselves.
… Man is responsible for what he is. Thus existentialism’s first move is to make every man aware of what he is and to make the full responsibility of his existence rest on him. And when we say that a man is responsible for himself, we do not only mean that he is responsible for his own individuality, but that he is responsible for all men.
