§3 [18-19]


Thus every πρᾶξις, every νοεῖν, is a movement.

Speaking is hence φωνή, a vocalizing which contains a ἑρμηνεία, i.e., which says something understandable about the world. And as this vocalizing, speaking is a mode of Being of what is alive, a mode of the ψυχή. Aristotle conceives this mode of Being as ἀληθεύειν. In this way, human life in its Being, ψυχή, is speaking, interpreting, i.e., it is a carrying out of ἀληθεύειν. Aristotle did not only, in the De Anima, found this state of affairs ontologically, but, for the first time and before all else, he saw and interpreted on that ground the multiplicity of the phenomena, the multiplicity of the various possibilities of ἀληθεύειν. The interpretation is accomplished in the sixth book of Nicomachean Ethics, chapters 2-6, 1138b35ff.

Accordingly, let us proceed to our interpretation of the sixth book of the Nicomachean Ethics. We will also refer to other writings of Aristotle.
