Being and Time

by Martin Heidegger

Being is always the Being of an entity.

Science in general may be defined as the totality established through an interconnection of true propositions.(1)

Dasein is an entity which does not just occur among other entities. Rather it is ontically distinguished by the fact that, in its very Being, that Being is an issue for it.

Dasein always understands itself in terms of its existence—in terms of a possibility of itself: to be itself or not itself.

The question of existence never gets straightened out except through existing itself.

The λόγος lets something be seen (φαίνεσθαι), namely, what the discourse is about; and it does so either for the one who is doing the talking (the medium) or for persons who are talking with one another, as the case may be.

Every reference is a relation, but not every relation is a reference.

This is interpreted as "(In regard to the referential totality) the act of reference suffices for instantiation of the import of there being a relation, although not necessarily vice versa."

To the substantia finita as res corporea, what must primarily be ‘assigned’ [“Zuweisung”] is the extensio.

If anything measures up in its own kind of Being to the Being that is accessible in mathematical knowledge, then it is in the authentic sense.

The Being of that disclosedness is constituted by states-of-mind, understanding, and discourse.

State-of-mind, Understanding (2), Discourse (3): "Disclosedness". SOM ∊ Disc, U ∊ Disc, DC ∊ Disc

Its everyday kind of Being is characterized by idle talk, curiosity, and ambiguity.

everday Disclosedness: Idle Talk, Curiousity, Ambiguity. ∀ID ∊ eD, ∀Cu ∊ eD, ∀Am ∊ eD

When does truth become phenomenally explicit in knowledge itself?

What is to be demonstrated is solely the Being-uncovered [Entdeckt-sein] of the entity itself—that entity in the “how” of its uncoveredness.

Only by the anticipation of death is every accidental and ‘provisional’ possibility driven out. Only Being-free for death, gives Dasein its goal outright and pushes existence into its finitude. Once one has grasped the finitude of one’s existence, it snatches one back from the endless multiplicity of possibilities which offer themselves as closest to one—those of comfortableness, shirking, and taking things lightly—and brings Dasein into the simplicity of its fate [Schicksals]. This is how we designate Dasein’s primordial historizing, which lies in authentic resoluteness and in which Dasein hands itself down to itself, free for death, in a possibility which it has inherited and yet has chosen.
