" Dasein exists as an entity for which, in its Being, that Being is itself an issue. Essentially ahead of itself, it has projected itself upon its potentiality-for-Being before going on to any mere consideration of itself. In its projection it reveals itself as something which has been thrown. It has been thrownly abandoned to the ‘world’, and falls into it concernfully.(1) As care—that is, as existing in the unity of the projection which has been fallingly thrown—this entity has been disclosed as a “there”. As being with Others, it maintains itself in an average way of interpreting—a way which has been Articulated in discourse and expressed in language. Being-in-the-world has always expressed itself, and as Being alongside entities encountered within-the-world, it constantly expresses itself in addressing itself to the very object of its concern and discussing it. The concern of circumspective common sense is grounded in temporality—indeed in the mode of a making-present which retains and awaits. Such concern, as concernfully reckoning up, planning, preventing, or taking precautions, always says (whether audibly or not) that something is to happen ‘then’, that something else is to be attended to ‘beforehand’, that what has failed or eluded us ‘on that former occasion’ is something that we must ‘now’ make up for.(2) "
