gr. διάνοια, dianoia: razão discursiva, pensamento discursivo.

---

Discursive reason (dianoia), when it makes a judgement (epikrisis) on the imprints (tupoi) from sense perception, is already contemplating forms (eide), and contemplating them by a sort of self-awareness (sunaisthesis). At least discursive reason properly speaking, which belongs to the true soul, does this. [Plotinus   1.1 [53] 9 (18-21); SorabjiPC1  :39]

Sense perception saw a man and gave the imprint (tupos) to discursive reason (dianoia). What does discursive reason say? It will not yet say anything, but only notices and halts, unless it were to calculate to itself ‘Who is this?’, if it had encountered this man before, and were to say, using its memory, that it is Socrates  . But if it were also to explicate Socrates’ shape, it will be taking to pieces what imagination (phantasia) gave it. And if it were to say whether Socrates is good, though it would have spoken on the basis of what it noticed through sense perception, what it said about that it would have from itself, since it has in itself a criterion (kanon) of goodness. [Plotinus 5.3 [49] 3 (1-9); SorabjiPC1:39]
