For almost five million years, humans have been locked in a relationship with morality, inventing and reinventing the concepts of 'Good' and 'Evil', and weaving them into our cities, laws and customs.

Morality is a concept that can feel joyless and claustrophobic, associated with restraint and coercion, restriction and sacrifice, inquisition, confession and a guilty conscience. For many, it is a device used to shame us into compliance. This impression is not necessarily incorrect, but it is most certainly incomplete.

Hanno Sauer traces humanity's fundamental moral transformations from our earliest ancestors through to the present day, when it can often seem that we have never disagreed more over what it means to be good, and what it means to be right. But we can use our past as a basis for a new understanding of our future. Our current political disagreements may feel like the end of the world, but where will the evolution of morality take us next?

This book develops a unified theory of moral progress. The author argues that there are mechanisms in place that consistently drive societies towards moral improvement and that a sophisticated, naturalistically respectable form of teleology can be defended.

In recent research, dual-process theories of cognition have been the primary model for explaining moral judgment and reasoning. These theories understand moral thinking in terms of two separate domains: one deliberate and analytic, the other quick and instinctive. This book presents a new theory of the philosophy and cognitive science of moral judgment. Hanno Sauer develops and defends an account of "triple-process" moral psychology, arguing that moral thinking and reasoning are only insufficiently understood when described in terms of a quick but intuitive and a slow but rational type of cognition. This approach severely underestimates the importance and impact of dispositions to initiate and engage in critical thinking - the cognitive resource in charge of counteracting my-side bias, closed-mindedness, dogmatism, and breakdowns of self-control. Moral cognition is based, not on emotion and reason, but on an integrated network of intuitive, algorithmic and reflective thinking. Moral Thinking, Fast and Slow will be of great interest to philosophers and students of ethics, philosophy of psychology and cognitive science.

In this crisply written book, Hanno Sauer offers the first book-length treatment of debunking arguments in ethics, developing an empirically informed and philosophically sophisticated account of genealogical arguments and their significance for the reliability of moral cognition. He breaks new ground by introducing a series of novel distinctions into the current debate, which allows him to develop a framework for assessing the prospects of debunking or vindicating our moral intuitions. He also challenges the justification of some of our moral judgments by showing that they are based on epistemically defective processes. His book is an original, cutting-edge contribution to the burgeoning field of empirically informed metaethics, and will interest philosophers, psychologists, and anyone interested in how - and whether - moral judgment works.
