Existentialism
The view that existence precedes essence and that nobody is exempt from responsibility.
What it commits you to
Existentialism, in its Sartrean form, holds that there is no pre-given human nature and that being is a project one undertakes with no guarantee of success. Its claim of universal responsibility is the part that tends to be misreported: Sartre was arguing against the charge that existentialism removes moral constraint. It is a poor fit for consequentialist optimisation and a good one for questions about who answers.
