tyche, clinamen and den. The contention is that all three aim at the status of the object, although by different means and in different philosophical contexts, and the paper tries to spell out some crucial points concerning each. Tyche, usually translated as chance and put into an opposition with automaton, requires a reading of some passages of Aristotle's Physics where Lacan took it from, and an account of the problem of repetition in psychoanalysis. Clinamen, the swerve, stemming from Epicure and Lucretius, requires a condensed reading of the tradition which took it up, from Cicero to Hegel, Marx, Deleuze and Badiou, pinpointing the dilemmas and contradictions of this tradition. Den, stemming from Democritus who coined this neologism, brings up an entity which is neither being nor nothing, neither one nor zero nor multiple. It is perhaps the best evocation, at the dawn of philosophy, of what Lacan would call object a, and it allows to sidestep the difficulties and the pitfalls presented by the other two notions. The paper tries to pin down the minimal requirement for the Lacanian theory with the irreducible and incommensurable (non)relation of "minus one' and den." /> Tyche, clinamen, den - Dolar Mladen | sdvig press
