Existence Precedes Essence: Jean-Paul Sartre's Existentialism and Human Emotions

In Jean-Paul Sartre's "Existentialism and Human Emotions," the author discusses the philosophical concept that existence precedes essence, a theory which involves elements of responsibility and freedom in regards to human choice. The idea that existence precedes essence means that a human being, as well as human reality, exists prior to any concepts of values or morals. A person is born a blank slate; humanity has no universal, predetermined principles or ethics common to all of mankind. Since no preformed essence or definition exists of what is means to "be human," a person must form his/her own conception of existence by asserting control of and responsibility for his/her actions and choices. Consequently, a human being gains his/her essence through individual choices and actions. It is solely through the process of living that one defines one's self.
