What kinds of conversations might take place when two intelligent and informed young people – one a strong believer in free will and the other just as certain that we don’t have it – get together to discuss their viewpoints? This new volume in the Philosophical Dialogues on Contemporary Problems series introduces both sides of this age-old philosophical debate in a fun and accessible way. Author and acclaimed philosopher Laura W. Ekstrom has created Rosa and Leif, two college students, who each give voice to the strongest arguments in the most important debates about free will and moral responsibility. Over the course of eleven days, Rosa, a strong defender of free will, draws on her religious beliefs and her thoughts about love and meaning in human life. Leif, her equally informed and articulate interlocutor, raises challenges to Rosa’s points, drawing on the latest research and ideas in neuroscience, theology, and social psychology. Along the way, they must carefully develop clear reasons for their positions, while offering a fair hearing to alternative viewpoints and spurring readers to reach their own conclusions. Working in a philosophical tradition established by Plato, these dialogues are both philosophically substantive and provocative, inviting readers to ponder issues that are fundamental to our understanding of the nature of choice, responsibility, and ourselves as human beings.
