Thus, the transitoriness of our existence in no way makes it meaningless. But it does constitute our responsibleness; for everything hinges upon our realizing the essentially transitory possibilities. Man constantly makes his choice concerning the mass of present potentialities; which of these will be condemned to nonbeing and which will be actualized? Which choice will be made an actuality once and forever, an immortal “footprint in the sands of time”? At any moment, man must decide, for better or for worse, what will be the monument of his existence.
