  Thrownness and projection provide two of the three dimensions of care. The third is fallen-ness. “Dasein has, in the first instance, fallen away from itself as an authentic potentiality for Being its Self, and has fallen into the world” (Being and Time 38: 220). Such fallen-ness into the world is manifested in idle talk (roughly, conversing in a critically unexamined and unexamining way about facts and information while failing to use language to reveal their relevance), curiosity (a search for novelty and endless stimulation rather than belonging or dwelling), and ambiguity (a loss of any sensitivity to the distinction between genuine understanding and superficial chatter). Each of these aspects of fallen-ness involves a closing off or covering up of the world (more precisely, of any real understanding of the world) through a fascination with it. What is crucial here is that this world-obscuring process of fallen-ness/fascination, as manifested in idle talk, curiosity and ambiguity, is to be understood as Dasein's everyday mode of Being-with. In its everyday form, Being-with exhibits what Heidegger calls levelling or averageness—a “Being-lost in the publicness of the ‘they’ ” (Being and Time 38: 220). Here, in dramatic language, is how he makes the point.
