In his search to understand his individuality, man faces many questions, among them: What is freedom? What do we actually mean when we talk about human freedom? By engaging in logical debates and disagreements, many philosophers have addressed specific issues regarding human freedom, which has led them to make claims about certain concepts and errors. Based on this context, this study embraces a critical examination of freedom and responsibility in Jean-Paul Sartre's view as a path to actual living. In Sartre's view, freedom is the essence of man since it is rooted in nothingness, unconstrained by anything, and has nothingness as its source. The research study in question uses the critical analysis methodology. As a result of the principle that "existence precedes essence," which states that a person is without an essence before they are born, research indicates that man first creates his own essence. Through free will and determination, man builds self. This research effort aims to reawaken in man the essential truth that man's freedom is unavoidably accompanied by a heavy and unavoidable duty, which is a necessary requirement for true self-existence. Only when we accept responsibility for the significance of our past and present and intentionally choose our future can we truly achieve the value Sartre has seen it embrace.
