Abstract:
This qualitative study aimed to analyze Francis Jeanson's development of Sartre's existentialist ethics in his
major work, Sartre and the Problem of Morality. The study methods included documentary research and critical
analysis.
The results of the study showed that most moral philosophers who study and criticize Sartre's ethics mainly
rely on one of Sartre's works, Existentialism is Humanism. Jeanson points out that this work is inadequate as a
complete articulation of Sartre's ethical framework, and therefore he embarks on the analytical attempt to derive
a coherent system of Sartrean ethics from Sartre's wide array of works, philosophical and literary.
The product is not only an elaboration of authentic moral orientation for an individual, which mainly
focuses on moral conversion through purifying reflection, the change from factual freedom to freedom-asvalued,
but also an extension beyond the limit of individual concern to a social perspective which connects the
imperative of individual authentic choice to "By choosing myself, I choose for everyone else. This individual
choice is the logical articulation of why responsibility for one' own choice is also one for humanity on the basis
of re-definition of 'Ethics' as the study of conditions that promote social members' realization of authentic
freedom. Therefore, all the criticisms directed towards the implication of moral nihilism in Sartre's ethics are
nullified.
It is suggested that a further study should be conducted on the role of purifying reflection and existential
psychoanalysis in realizing authenticity. Moreover, the possible role Marxism may play in the creation of a
condition for social members' realization of authentic freedom should also be studied.
