The final responsibility of deciding is given to man himself. They are open and yet to be decided. Man will do the deciding. 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.
