The lover demands an oath and is annoyed by it. He wants to be beloved by freedom and demands that this freedom as freedom would no longer be free." These words of J.-P. Sartre could be the motto of his life. In 1929, instead of hand heart, Sartre proposed to his beloved to conclude the "Manifesto of Love": to be together, but at the same time to remain free. Simon de Beauvoir, who more than anything else grew up with her reputation as a free-thinking person, was quite happy with this formulation of the question.
