A new and accurate translation of an important work of ancient Greek scepticism.

Blank presents a new translation into clear modern English of a key treatise by one of the greatest of ancient philosophers, together with the first ever commentary on this work. Sextus Empiricus's Against the Grammarians is a polemical attack on ancient Greek ideas about grammar, and provides one of the best examples of sustained Sceptical reasoning.

Arithmetic deals with numbers: but what is the nature of their existence, of their parts, and of their relationship with countable items? These questions nourished a lively debate between the Platonico-Pythagorean tradition (trying to answer them) and the Pyrrhonian tradition (trying to show that these answers were unsatisfactory). The debate lies at the heart of Sextus Empiricus’ Against the Arithmeticians. The present book aims at facing the remarkable historical and philosophical questions raised by Sextus’ treatise by offering a new translation of it and the first dedicated commentary to it.

Sextus Empiricus: Against Those in the Disciplines (Pros Mathematikous, also known by the abbreviated title M 1-6) deals with six specialized fields of study: grammar, rhetoric, geometry, arithmetic, astrology, and music. In sceptical fashion, it questions the credentials of those who claim to have expert knowledge in these fields. It is the least well known of Sextus Empiricus' works, mainly because its subject-matter is not directly philosophical; some of its arguments require knowledge of these fields as they existed in the ancient world, which philosophers (Sextus' main readership) tend not to have. But it is a good specimen of Sextus' usual sceptical method of inducing suspension of judgement about the topics under consideration, and it contains much that is of philosophical interest. This volume aims to bring this work to a wider philosophical audience and to make the technicalities of the fields discussed understandable to non-specialists. It contains a translation of the work into clear modern English, accompanied by extensive explanatory notes. For ease of comprehension, the text is broken down into named sections and subsections, and these are also listed separately before the translation (the Outline of Argument). An introduction discusses the place of Against Those in the Disciplines in the totality of Sextus' work, and examines certain features that are distinctive to it. Other aids to the reader are a list of persons referred to in the work, with brief information about each; an English-Greek and Greek-English glossary of key terms; and a list of passages in other works of Sextus that are parallel to passages in this work.

Throughout history philosophers have sought to define, understand, and delineate concepts important to human well-being. One such concept is "knowledge." Many philosophers believed that absolute, certain knowledge, is possible—that the physical world and ideas formulated about it could be given solid foundation unaffected by the varieties of mere opinion.Sextus Empiricus stands as an example of the "skeptic" school of thought whose members believed that knowledge was either unattainable or, if a genuine possibility, the conditions necessary to achieve it were next to impossible to satisfy. In other words, in the absence of complete knowledge, one must make do with the information provided by an imperfect world and conveyed to the mind through sense impressions that can often deceive us. Throughout his life Sextus Empiricus entered into intellectual combat with those who confidently claimed to possess indubitable knowledge. For skeptics, the best one can hope to achieve is a reasonable suspension of judgment—remaining ever mindful that claims to knowledge require careful scrutiny, thoughtful analysis, and critical review if we are to prevent ourselves and others from plunging headlong into mistaken notions.

In this unjustly neglected and misunderstood work Sextus sets out a distinctive Sceptic position in ethics. He discusses the concepts good and bad, and puts forward the sceptical argument that nothing is either good or bad by nature or intrinsically or invariably, but only relatively to persons and/or to circumstances. He then argues that the sceptic is better off than the non-sceptic. In the latter part of the book, Sextus attacks the Stoic view that there is such a thing as a 'skill for life'.

The first comprehensive study of the function and value of aporia, or puzzlement, as a key tool in ancient philosophical enquiry.
