 Tying together the themes of difference, multiplicity, virtuality and intensity, at the heart of Difference and Repetition we find a theory of Ideas (dialectics) based neither on an essential model of identity (Plato), nor a regulative model of unity (Kant), nor a dialectical model of contradiction (Hegel), but rather on a problematic and genetic model of difference. Ideas define the being of a thing, but one cannot attain an Idea through the Socratic question “What is … ?” (which posits Ideas as transcendent and eternal), but rather through “minor” questions such as “Which one?” “Where?” “When?” “How?” “How many?” “In which case?” “From which viewpoint?”—all of which allow one to define the differential Ideas immanent in the intensive processes they structure.
