This quote implies a deep admiration for the philosophy and teachings of Ali Shariati, an influential Iranian sociologist and thinker. While Sartre himself was not religious, he saw great value in Shariati’s approach to religion, which was progressive, socially conscious, and humanistic. Essentially, Sartre is saying that if he were to choose a religion, it would be one that aligns with these principles.

Shariati’s philosophy was a unique blend of Marxism and Islam, emphasizing social justice, equality, and human dignity. He argued against religious dogmatism and instead advocated for a dynamic and revolutionary interpretation of Islam that could serve as a force for social change.

In today’s world, this quote can be seen as a call for a more progressive, inclusive, and socially conscious approach to religion. It suggests that religion should not be a source of division, conflict, or oppression, but a force for unity, justice, and human dignity. This idea can be applied in personal development by encouraging individuals to question dogmatic beliefs, strive for social justice, and respect the dignity of all people, regardless of their religious beliefs.

Moreover, it can inspire individuals to seek spiritual growth and personal development not through blind adherence to religious dogma, but through critical thinking, social engagement, and a deep respect for human dignity. This can lead to a more holistic and fulfilling approach to personal development that combines spiritual growth with social consciousness.

In essence, Sartre is suggesting that the best ‘religion’ is one that promotes social justice, human dignity, and critical thinking – principles that are as relevant today as they were in Shariati’s time.
