The book discussed herein was compiled after Alasdair MacIntyre presented his lecture at Edinburgh, as well as Yale, and largely focuses on the differences between these audiences to outline his point on the gaps between schools of philosophy. MacIntyre discusses three very different and mutually antagonistic conceptions of moral enquiry, each stemming from a seminal late nineteenth-century text: the ninth edition of the Encyclopaedia Britannica, Nietzsche’s Zur Genealodie De Moral and Pope Leo XIII’s Aeterni Patris. MacIntyre lays out the issues in the opening chapters by placing the purpose of the Gifford series within the current context of philosophical debate, and traces the roots of dissent through the past few centuries of philosophy. The remaining chapters discuss the Augustinian, Aristotelian and Thomistic viewpoints of moral enquiry. MacIntyre concludes with discussion of tradition and genealogy in the areas of knowledge, information and philosophical understanding. His views on re-conceiving the university and the lecture as an institution and a genre are highly persuasive towards more productive philosophical debate. The most that one can hope is for these disagreements to become more constructive. It was with that aim that MacIntyre delivered and published these lectures.
