What do Neurosciences Talk About When They Talk About Free Will?

In this paper, I will take into account and criticize two of the most celebrated neuroscientific experiments about free will, which seem to deny that agents freely deliberate about simple choices of their everyday life: the pioneering experiment of Benjamin Libet and the more recent one of John Dylan Hayes. My aim is to reject the relevance of their empirical results, which deny the existence of free will. However, such a rejection will not rely on criticisms about how the experiments are conducted. Instead, I would like to bring about a broad philosophical and methodological concern: namely, that the success or the failure of the experiments in arguing for the illusion of free will is strictly dependent on the meaning of the notion of free will which is put through an experimental investigation.
