Just as we cannot think of spatial objects at all apart from space, or temporal objects apart from time, so we cannot think of any object apart from … - Ludwig Wittgenstein

we cannot think of any object apart from the possibility of its connexion with other things.

There can never be surprises in logic.

5.641 [...] Das philosophische Ich ist nicht der Mensch, nicht der menschliche Körper, oder die menschliche Seele, von der die Psychologie handelt, sondern das metaphysische Subjekt, die Grenze - nicht ein Teil - der Welt.

To be sure, I can imagine what Heidegger means by being [Sein] and anxiety [Angst]. Man feels the urge to run up against the limits of language. Think for example of the astonishment that anything at all exists. This astonishment cannot be expressed in the form of a question, and there is no answer whatsoever. Anything we might say is a priori bound to be mere nonsense. Nevertheless we do run up against the limits of language.
