Passage du nihilisme biologique au nihilisme moral dans la pensée d'Alex Rosenberg
Evolutionary biology is at the center of contemporary debates about human behavior. Therefore the concepts of free will and morality in regard of these kinds of explanations should be studied. Today’s consensus posits that free will is only the experience of free will. The real question is more how this experience could take place in a Darwinian frame. However, others Darwinians seem to give free will a reality as well as accepting a Darwinian determinism. In this essay, Alex Rosenberg’s original position negating free will and determinism will be studied. More specifically, the physicalist and naturalist positions adopted by Rosenberg argues for the transition from the biological nihilism to moral nihilism. We will see how this transition illustrates Rosenberg’s position about free will and morality. To do so, the Second Law of Thermodynamics and the Theory of Natural Selection will be analyzed in the aim of demonstrating how they can be associated with the physicalist and naturalist positions. Finally, Alex Rosenberg’s arguments will be put in a metaethics frame to show a contradiction: moral nihilism might not be as nice as Rosenberg suggest.
