seminar room of group Science, Reason and Faith. 

José Manuel Muñoz Ortega. Pamplona, 20 September 2016. 


About speaker:

José Manuel Muñoz Ortega holds a PhD in Philosophy and graduate in Biology. He currently teaches the permanent training course "Neuroscience and free will" at the UNED and is a teacher at the I.E.S. Joan Ramis i Ramis in the Balearic Islands.


Benjamin Libet's experiments on the temporal sequence in the electrophysiology of certain voluntary acts have produced a discussion in Philosophy and neuroscience. Many authors have seen in them a convincing test against the existence of free actions. Other more recent experiments, carried out with fMRI or deep electrodes, seem to lead to the same conclusion. However, the argumentation followed by their advocates has been heavily criticised. This seminar room: outlines the essential features of the "subject Libet" experiments, shows the positions of prominent authors defending or refuting the argument against free will based on these experiments, and examines whether, in the light of the above, it can be rejected that humans have free will (libertarianism) and furthermore that it is incompatible with determinism.
