On §5
For the purpose of going back into Greek conceptuality and its indigenousness we start from something that is most familiar, from which the concept as such becomes explicit, now and for a long time: definition. In definition, the concept is genuinely concept. There we question back: How did it stand with definition for Aristotle? What did it mean for him? What are we to infer from this for the pre-understanding of conceptuality? Secondary object: to demonstrate the change that so harmless a thing as definition went through, change as decline from a basic possibility and mode of genuinely speaking with the world to a rule of thought-technique.

Ὁρισμός as λόγος οὐσίας:

IV. how does indigenous character look? i.e., where-to to what extent?
Phenomenon of equiprimordiality (only negative!). Cf. later.
