Answer
Yes, Hartmann's philosophy has influenced several contemporary philosophical theories. His concept of "ontological pluralism," which posits a multi-layered reality composed of different strata of being, has resonated with contemporary philosophers exploring similar ideas, such as the philosopher Graham Harman. Additionally, Hartmann's emphasis on the role of the unconscious and the irrational in human experience has influenced various thinkers within continental philosophy, such as Jacques Derrida and Gilles Deleuze.
