In the first half of the book Kane presents an overview of his current views with the significant additions and alterations to them spelled out and defended in greater detail. In the second half he critically examines the influential views of the many other philosophers of the past twenty-five years who have defended alternative views of free will and moral responsibility, including prominent defenders of competing libertarian views, compatibilist views, free will skeptical views, revisionist views, illusionist views, and others. Kane's goal here is not to merely criticize these alternative views, but to show what he believes they get right and what aspects of many of them can be accommodated in the views of free will, moral responsibility, and other related topics defended in the book. His conclusion connects his views to certain ethical views he has developed, and to ideas in the philosophy of religion, including Eastern religions (Hinduism, Buddhism) and Western and Middle Eastern theistic traditions (Judaism, Christianity, and Islam).

The Complex Tapestry of Free Will presents an up-to-date overview of the current state of arguments and views on free will and related topics of moral and legal responsibility in ethics, law, science and religion, accessible to those not already familiar with the free will literature, while also developing novel and complex ideas on difficult subjects.
