In Sartre's own words, we are 'thrown into liberty' (nous sommes jetés dans la liberté) or condemened to freedom (condamnés a la liberté). These phrases indicate that freedom can be experienced as burden or penance. First the authoress reviews opinions on liberty expressed by Descartes and Kant. Then she contrasts them with the conception worked out by Sartre, who emphasizes that freedom is something more than the power to choose. It is also an obligation to view oneself as a differentiating and discriminating subject called upon to assign meaning and value to different situations in the world. By taking up this task human individuals create in nature a whole new world of purposes and ends. If, however, they fail to execute this responsibility, they slide back into the status of passive and irresponsible parts of nature.
