Wishful thinking is a deeply ingrained human trait that has had a long-term distorting effect on ethical thinking. Many influential ethical views depend on the optimistic assumption that, despite appearances to the contrary, the human and natural world in which we live could, eventually, be made to make sense to us. In A World without Why, Raymond Geuss challenges this assumption.

"Geuss is a unique voice in contemporary philosophy, and this book is ideal for anyone interested in intellectual history."--David Gordon, Library Journal
