In Heidegger's view, man has a tendency to lose himself in his world and "forget" his mortality, and by extension that of his world. He falls in with the crowd (the "they"), engages in idle chatter, lets himself be absorbed by average everydayness all in order to avoid the fundamental question of his existence and its responsibility. We are inauthentic creatures: […] Heidegger claims, a confrontation with our finitude, an "authentic being-toward-death." It would mean heeding the call of conscience, to exhibit "care" toward the manifestation of Being. And above all, it would demand a new “resoluteness”, which signifies “letting oneself be summoned out of one's lostness in the ‘they.’”
Could you please help me with understanding the bold passage from the above excerpt. It comes from Heidegger's Being and Time. (I am especially confused by the phrase "to be summoned out of".) Does it mean that the man to live the authentic life should gather one's strength and experience his/her lostness outside of the crowd, outside of the other people?
