Being and Time

That the world does not 'consist' of the ready-to-hand shows itself in the fact (among others) that whenever the world is lit up in the modes of concern which we have been Interpreting, the ready-to-hand becomes deprived of its worldhood so that Being-just-present-at-hand comes to the fore. If, in our everyday concern with the 'environment', it is to be possible for equipment ready-to-hand to be encountered in its 'Being-in-itself' [in seinem "An-sich-sein"], then those assignments and referential totalities in which our circumspection 'is absorbed' cannot become a theme for that circumspection any more than they can for grasping things 'thematically' but non-circumspectively. If it is to be possible for the ready-to-hand not to emerge from its inconspicuousness, the world must not announce itself. And it is in this that the Being-in-itself of entities which are ready-to-hand has its phenomenal structure constituted.

In such privative expressions as "inconspicuousness", "unobtrusiveness", and "non-obstinacy", what we have in view is a positive phenomenal character of the Being of that which is proximally ready-to-hand. With these negative prefixes we have in view the character of the ready-to-hand as "holding itself in"; this is what we have our eye upon in the "Being-in-itself" of something, 1 though 'proximally' we ascribe it to the present-at-hand-to the present-at-hand as that which can be thematically ascertained. As long as we take out orientation primarily and exclusively from the present-at-hand, the 'in-itself' can by no means be ontologically clarified. If, however, this talk about the 'in-itself' has any [76] ontological importance, some interpretation must be called for. This "in-itself" of Being is something which gets invoked with considerable emphasis, mostly in an ontical way, and rightly so from a phenomenal standpoint. But if some ontological assertion is supposed to be given when this is ontically invoked, its claims are not fulfilled by such a procedure. As the foregoing analysis has already made clear, only on the basis of the phenomenon of the world can the Being-in-itself of entities within-the-world be grasped ontologically.

But if the world can, in a way, be lit up, it must assuredly be disclosed. And it has already been disclosed beforehand whenever what is ready-to-hand within-the-world is accessible for circumspective concern. The world is therefore something 'wherein' Dasein as an entity already was, and if in any manner it explicitly comes away from anything, it can never do more than come back to the world.

1 'Diese "Un" meinen den Charakter des Ansichhaltens des Zuhandenen, das, was wir mit dem An-sich-sein im Auge haben ...' The point seems to be that when we' speak of something 'as it is "in itself" or "in its own right" ', we think of it as 'holding itself in' or 'holding itself back'-not 'stepping forth' or doing something 'out of character'.
