Jean-Paul Sartre faced numerous obstacles in his philosophical career, including pervasive political criticism and societal backlash. His outspoken views on existentialism, freedom, and choice often challenged societal norms, leading to conflicts with authorities and peers. Additionally, his anti-establishment stance occasionally alienated potential supporters. Sartre's struggles with mental health may have compounded these difficulties, influencing his philosophical inquiries into authenticity and the human condition. Despite these challenges, he maintained a prolific career, becoming a leading figure in 20th-century philosophy and literature, with works like "Being and Nothingness" and "Nausea" solidifying his legacy.
