Being and Time

rather a deficient mode of the Present in the sense of the making-unpresent [Ungegenwärtigens] of something which one has expected or which one has always had at one's disposal. If, when one circumspectively lets something be involved, one were not 'from the outset' awaiting the object of one's concern, and if such awaiting did not temporalize itself in a unity with a making-present, then Dasein could never 'find' that something is missing [fehlt] .

On the other hand, when one is making present something ready-to-hand by awaiting, the possibility of one's getting surprised by something is based upon one's not awaiting something else which stands in a possible context of involvement with what one awaits. In the not awaiting of the making-present which is lost, the 'horizonal' leeway within which one's Dasein can be assailed by something surprising is first disclosed.

That with which one's concernful dealings fail to cope, either by producing or procuring something, or even by turning away, holding aloof, or protecting oneself from something, reveals itself in its insurmountability. Concern resigns itself to it.1 But resigning oneself to something is a mode [356] peculiar to circumspectively letting it be encountered. On the basis of this kind of discovery concern can come across that which is inconvenient, disturbing, hindering, endangering, or in general resistant in some way. The temporal structure of resigning oneself to something, lies in a non-retaining which awaitingly makes present. In awaitingly making present, one does not, for instance, reckon 'on' that which is unsuitable but none the less available. "Not reckoning with" something, is a mode of "taking into one's reckoning" that which one cannot cling to. That which one has "not reckoned with" does not get forgotten; it gets retained, so that in its very unsuitability it remains ready-to-hand.2 That which is ready-to-hand in this manner belongs to the everyday stock or content of the factically disclosed environment.

Only in so far as something resistant has been discovered on the basis of the ecstatical temporality of concern, can factical Dasein understand itself in its abandonment to a 'world' of which it never becomes master. Even if concern remains restricted to the urgency of everyday needs, it is never a pure making-present, but arises from a retention which awaits; on the basis of such a retention, or as such a 'basis', Dasein exists in a world. Thus in a certain manner, factically existent Dasein always knows its way about, even in a 'world' which is alien.

1 'Das Besorgen findet sich damit ab.'

2 'Die zeitliche Struktur des Sichabfindens liegt in einem gewärtigend-gegenwärtigenden Unbehalten. Das gewärtigende Gegenwärtigen rechnet zum Beispiel nicht "auf" das Ungeeignete, aber gleichwohl Verfügbare. Das Nichtrechnen mit ... ist ein Modus des Rechnungtragens dem gegeniiber, woran man sich nicht halten kann. Es wird nicht vergessen, sondern behalten, so class es gerade in seiner Ungeeignetheit zuhanden bleibt.'
