The following is a presentation and discussion with David McKerracher focusing on the Conclusion of Alenka Zupančič's What Is Sex? This presentation covers the centrality of Zupančič's onto-epistemological short-circuit, the difference between the sexual and knowledge drive, the gap/lack that drives family and social structures, the way in which traditional cultures cover nothing, the importance of the "dream's navel" in psychoanalysis, and the double unknown in Alenka's onto-epistemology, the unknown in our knowledge and the unknown in being itself.
