It cannot be predicted how he will work out his existence. Man's salvation lies within man. Man is first physical but the existentialist allows also for the spiritual part of man. There is unity in man. His existence is in the search for that unity and essence.
Truth is what the individual decides it is.
He or she makes his or her own truth by the choices he or she makes in life. Truth is something he or she chooses, not something to be chosen. Truth resides in the subject, not in the object. Truth resides in the individual, not in the world. To the Existentialist, knowing comes by participating and by acting out the drama of life.
