§110 [208-209]

7. How the discrepancy in their essence and in their relation to the "I" and to "consciousness" ultimately comes to count in Leibniz and Kant as something fixed and conceptually determined, which happened earlier with the interpretation of beings as οὐσία. (How even Nietzsche does not ask radical questions here.)

109. Ἰδέα

is that interpretation of ἀλήθεια which prepares the later determination of beingness as objectivity and necessarily forecloses to the entire history of Western philosophy the question of ἀλήθεια as such

Only another inceptual thinking of being and of its relation to Dasein can give rise to the question of what was called ἀλήθεια in the thinking of the first beginning.

110. The ἰδέα, Platonism, and idealism12

1. The concept of ἰδέα (εἶδος): the look of something, what something gives itself out to be and makes of itself, that in which something is set back and thus is the being it is. Although ἰδέα is related to ἰδεῖν (νοεῖν), the word does precisely not mean the represented of a representing. On the contrary, it means the shining forth of the look itself, what offers up a view and does so for a gaze. The word does precisely not signify a relation to the "subject" in the modern sense. It refers rather to the presencing, the shining forth, of the view in the look and specifically as that which in coming to presence provides constancy at the same time. Here originates the distinction between the τί ἐστὶν ["what it is"] (essentia, quidditas) and on ["that it is"] (existentia) in the temporality of the ἰδέα (cf. The leap). A being is a being in virtue of constant presence, ἰδέα, the seen in its seen-ness (ἀλήθεια).

2. The ἰδέα: that to which the changing, many things are referred back, the unifying One. Therefore: ὄν, being [seiend] = unifying. As a consequence, with respect to its many instantiations (ἔκαστα) the ἰδέα is the κοινόν, and the κοινόν, this later-derived determination of the ἰδέα as beingness, then remarkably becomes the first and ultimate determination of beingness (or of being). And so

12. Cf. The leap, 119. The leap is prepared by asking the basic question; cf. lecture course, Grundfragen der Philosophie: Ausgewählte "Probleme" der "Logik." winter semester 1937-38 (GA45). p. 60ff.
