University of Victoria instructor and co-author, with D. Thomson, of Sanchez: That Nothing is Known. Cambridge UP, 1989.

From Amazon publicity:

This is an edition of one of the crucial texts of Renaissance skepticism, Quod nihil scitur, by the Portuguese scholar Franciso Sanchez. The treatise, first published in 1581, is a refutation of Aristotelian dialectics and scientific theory in the search for a true scientific method. This volume provides a critical edition of the original text, an English translation (the first ever published), a substantial introduction, and comprehensive annotation.
