An attractive aspect of Thorsrud's exposition is that he continuously reflects on the sense and soundness of the ancient skeptical stances and explains them both in their own terms and with reference to our current way of seeing things. In other words, he adopts a more philosophic approach by considering the problems addressed by the ancient skeptics or posed by their outlooks, instead of providing an exclusively historical or doxographical presentation of past philosophical views. Written in a style which is straightforward and readable, this volume is a valuable addition to the literature on ancient skepticism. I highly recommend this book to those intending to embark on the systematic study of ancient skepticism or who just want to get an authoritative overview of the field. - Bryn Mawr Classical Review A well-written account, presented with lucidity and elegance.A - R.
