QUOTE : Here, then, awaiting our study, lies man's authentic "being"—stretching the whole length of his past. Man is what has happened to him, what he has done. Other things might have happened to him or have been done by him, but what did in fact happen to him and was done by him, this constitutes a relentless trajectory of experiences that he carries on his back as the vagabond his bundle of all he possesses. Man is a substantial emigrant on a pilgrimage of being, and it is accordingly meaningless to set limits to what he is capable of being.
