Jean Paul Sartre´s Existential Philosophy

According to Sartre, individuals are released from the moment they were born and continue to exist throughout their lives to determine their personality. Since the character of the individual is what we are doing now that we have done in the past, our character has never been fully defined before we lose the ability to act immediately after death. After we finally finish, we are defined by others as our action, success and failure accumulation and consequences. Before the essence, we are created without the help of a higher life.

The philosophical career of Jean Paul Sartre (1905-1980) focused on building the existential philosophy called the existentialism in its first stage. Early works of Sartre are characterized by the development of classical phenomenology, but his idea is different from Husserl's interest in methodology, self-concept, morality. These branch points are the cornerstone of Sartre's existential phenomenology and its aim is not to understand the world itself but to understand the existence of human beings. By adopting and adapting the phenomenological method, Sartre began to develop ontologies about what it is. The main feature of this ontology is fundamental freedom without evidence, which is a characteristic of human condition. These are in stark contrast to the fact that there is no problem in the world of things. Sartre's substantial literary work always creates unstable facts and dramatic expressions of freedom in an indifferent world.

The theory of Jean-Paul Sartre considers that existentialism is a kind of humanism that exchanges consciousness and existential thinking, what it means, and the nature of ontology. Throughout his philosophy, Sartre said that it is self, "the existence of a person must precede its essence" (Sutter 318). Understanding what "yes" means to recognize a universal way of thinking in the existence of a single human being

Existentialism was founded by Jean-Paul Sartre, in favor of Martin Heidegger's claim that mankind existed before nature. "Essence" is the cornerstone of all metaphysical philosophy and rationalism, but the statement of Sartre is the denial of his previous philosophical system (in particular the philosophical system of Husserl, Hegel and Heidegger). Rather than creating "reality" he believes that existence and reality are first and that essence is later. The most important thing for Kierkegaard is that the moral entity is an individual and the subjective aspect of human life is the most important, and for Kierkegaard all of them have a religious connotation .
