Final answer:
The claim that Sartre advocates withdrawing from human endeavors is false. Sartre's existentialist philosophy asserts that we are free and must actively engage with our freedom, taking responsibility for our actions to define our essence.
Step-by-step explanation:
The statement that Sartre advocates withdrawing from human endeavors is false. Jean-Paul Sartre, a prominent existentialist philosopher, argued that humans are fundamentally free and that we must take responsibility for our choices and actions. According to Sartre, humans are being-for-itself, which means that we are conscious, free, and defined by the decisions we make and the actions we take. This notion of freedom is central to Sartre's philosophy and he emphasizes that we are 'condemned to be free', implying that we cannot escape our freedom, but rather must constantly engage with it and the responsibility it entails.
For Sartre, existence precedes essence, which means that we first exist and then create our essence or meaning through our choices and actions. Far from advocating withdrawal, Sartre's existentialism requires active participation in life to define oneself and to take responsibility for one's freedom. His existentialist philosophy calls for an embrace of this radical freedom, despite the anxiety or 'nausea' it may cause, as it is integral to human existence and authenticity.
