The Good Life is an expression that represents how one would like to live one's life. In other words, how that person achieves happiness. There are three theories related to the Good Life: Daoism, Stoicism, and Existentialism. Since each person defines their happiness differently, everyone has their own opinion on whether what they read is correct or not. The goal is to at least shed some light on what everyone seems drawn to. Existentialism is an important theory to consider in achieving the good life. While existentialism may not appeal to everyone as a reliable theory for achieving the good life, it explains how existentialism can be used to achieve the good life. Jean-Paul Sartre is a well-known existentialist writer who, in his article “ Existentialism is a Humanism ,” discusses in detail what existentialism is, “a doctrine that makes human life possible and also states that every truth and every action they imply an environment and a human subjectivity” (Sartre 18). From this quote we can deduce that everything said and done is subject to fair judgment. Sartre goes on to describe the point of view of an existentialist. An existentialist “claims that if God does not exist, there is at least one being in which existence precedes essence, a being whose existence comes before its essence, a being that exists before it can be defined by any concept of it.” (Sartre 22 ). This quote explains that God is the being that existed before classification, but gave spiritual power to the world known today. Later in his article, Sartre describes subjectivism and what it means. “Subjectivism means the freedom of the individual subject to choose what will be, and the inability of man to transcend human subordination... middle of paper... Kierkegaard's different views are therefore the best-known existentialist views. Existentialism is a surprisingly popular theory of the good life today. Regardless of whether or not people have the same vision of a life worth living or existentialism, existentialism may prove to be a useful theory that could be used to achieve that life worth living.
