This book on infinite regress arguments provides (i) an up-to-date overview of the literature on the topic, (ii) ready-to-use insights for all domains of philosophy, and (iii) two case studies to illustrate these insights in some detail. Infinite regress arguments play an important role in all domains of philosophy. There are infinite regresses of reasons, obligations, rules, and disputes, and all are supposed to have their own moral. Yet most of them are involved in controversy. Hence the question is: what exactly is an infinite regress argument, and when is such an argument a good one?

Philosophers have long agreed that moral responsibility might not only have a freedom condition, but also an epistemic condition. Moral responsibility and knowledge interact, but the question is exactly how. Ignorance might constitute an excuse, but the question is exactly when. Surprisingly enough, the epistemic condition has only recently attracted the attention of scholars. This volume sets the agenda. Sixteen new essays address the following central questions: Does the epistemic condition require akrasia? Why does blameless ignorance excuse? Does moral ignorance sustained by one's culture excuse? Does the epistemic condition involve knowledge of the wrongness or wrongmaking features of one's action? Is the epistemic condition an independent condition, or is it derivative from one's quality of will or intentions? Is the epistemic condition sensitive to degrees of difficulty? Are there different kinds of moral responsibility and thus multiple epistemic conditions? Is the epistemic condition revisionary? What is the basic structure of the epistemic condition?
