The philosopher Alfred Mele presents in this book a fascinating critical study on the debate of the existence or not of free will. Questions about free will, conscience and freedom of human action have been the subject of debate among theologians, philosophers and scientists for a long time. For some years, controversial voices have emerged within the field of neuroscience that claim to have proven the non-existence of free will. Effective intentions combine scientific evidence with argumentation and philosophical analysis to demonstrate that the conclusions obtained from certain neuroscientific data are not conclusive to deny the ability to choose. Within the framework of a theme that is currently very relevant within the philosophy of mind and neuroscience, this book, winner of the 2013 Sanders Book Prize of the American Philosophical Association, will be illuminating for those who wish to delve into the framework of paradoxes that the relationship between the biological body and the freedom of the conscience and its actions.
