113. Ἰδέα and οὐσία
The task is to show how all essential determinations of beings are acquired out of the basic determination of beings (or of beingness) as constant presence or, to put it better, with this determination as the defining background.
According to that basic determination, what is is what is all at once, what can fulfill the possibility of the "all at once." From the "all at once" is determined the successive, i.e., the preceding and the following (later, cause and effect); note the Kantian interpretation of causality.
It is characteristic of the subsequent period of metaphysics that the temporal characterization is indeed employed to distinguish beings respectively, but here already time is in play only as a number applied to changing things, i.e., time is something that can be numbered, a form by which to order changing things. Thus time is employed as a framework. In other words, the more original essence of time never comes to be experienced, as little as does that of space. Οὐσία as "substance" is in this way posited as time-free, so to speak, in order to be determined afterwards as either "eternal" (infinite) or "temporal" (finite). Metaphysics does not ever get beyond this framework. Being and Time therefore seems to be self-evident!
114. On Nietzsche's basic metaphysical position14
There the question of "hierarchy" and indeed not with respect to "values" in general and in themselves but with respect to being human: the master and the slave
How is this question connected to metaphysics and to the basic metaphysical position? On that, cf. the development of the guiding question:
The human being and humankind [der Mensch und das Menschsein] as questioner, as grounding truth.
