The conference will conclude the IKKM six-year research program ‘Operative Ontologies’ which was structured along polar, complementary or gradual pairs of operations, which in themselves function as dualities or duplicities. Opening and closing, framing and sewing, appearing and disappearing, coupling and separating, compressing and dispersing, pointing and causing, reproduction and multiplication, or recursion and reflection were each examined as interrelated couples of ontological operations. As a continuation of this pairing method, the IKKM invites contributors to present papers on ontologically relevant pairs of operations that may or may not explore one of the examples mentioned above or others – for instance folding and unfolding, or, in a recursive manner, the operations of pairing and cleaving themselves.
