We might even talk of 'logjects', taking into account Martin Heidegger's reconstruction of aristotelian logos (in Grundbegriffe der Metaphysik / The Fundamental Concept of Metaphysics, §§ 71-74) as the formal indication (formale Anzeige) of our human way to form our world. A catject is a category relying on logos's capacity to diabolically and symbolically, via diarhesis and synthesis, differentiate and integrate the world inhabited by man. We only reach an understanding of it by looking at what we actually do, not just at how we talk about what we do and what we understand of what we are doing. What we are doing is using the space opened by logos draw distinctions inside a world formerly devoid of these distinctions, and to connect again what, via these distinctions, was separated by us. I propose to call catjects all forms of distinctions regarded with respect to both their act of separation and their act of re-connection.
