according to Existentialism: (1) Existence is always particular and individual—always my existence, your existence, his existence. (2) Existence is primarily the problem of existence (i.e., of its mode of being); it is, therefore, also the investigation of the meaning of Being. (3) This investigation is continually faced with diverse possibilities, from among which the existent (i.e., man) must make a selection, to which he must then commit himself. (4) Because these possibilities are constituted by man's relationships with things and with other men, existence is always a being-in-the-world—i.e., in a concrete and historically determinate situation that limits or conditions choice. Man is therefore called dasein(“there being”) because he is defined by the fact that he exists, or is in the world and inhabits it.
