Simone de Beauvoir has this to say, which corrects so many of the clichés about existentialism: “It is not true that the recognition of the freedom of others limits my own freedom. To be free is not to have the power to do anything you like; it is to be able to surpass the given toward an open future: the existence of others as a freedom defines my own situation and is even the condition of my own freedom.” (Ethics of Ambiguity, p. 91)
