Sartre and the Falsification of Meaning:Ontology of being for itself and its Relationship with Concrete Ethics

Man is the only creature that needs meaning. He needs meaning as symbolic food as much as he needs food to survive. It is in this context that the meaning of life - one of the most important philosophical, psychological and religious issues - has been investigated from different perspectives and it has been discussed in different areas. In general, there are two views about meaning among thinkers and philosophers. Philosophers who consider meaning as an objective, external and "revealed" thing and philosophers who consider it as an internal, subjective and "unknown" thing that arose from within the human being which is subjective and its source is the will, choices and commitments of the human being. Sartre, too is among the thinkers who consider meaning as an internal and falsifiable matter. In this research, we try to answer the most important problem of today's human beings’ lives through the falsification of meaning by examining the relationship between the ontology of being for itself and concrete ethics in Sartre's philosophy. According to Sartre, a person does not have a predetermined and fixed nature; his nature is constantly being constructed by his choices. Man, as a living being, relying on his freedom, can create moral values approved by himself and his society, and by creating a sense of commitment, he can forge a meaning for life.
