Plato’s Use of <i>Qua</i> Qualifications in the <i>Parmenides</i> and Their Role in the Metaphysics of the Forms

Abstract This paper focuses on the use of ‘ qua qualifications’ in Plato’s Parmenides to shed light on the purpose of both the dialogue as a whole and its parts. It shows that the compatible respects specified by qua and the metaphysics of qua qualifications in the second half of the Parmenides allow forms to have contrary features without being contradictory or collapsing into sensible beings – contrary to what the young Socrates fears in the first half of the dialogue. The discussion demonstrates the originality of Plato’s use of qua and contributes to a more unified understanding of the Parmenides .
