Ian Kidd, of the University of St. Andrews, Scotland, has long been known as a world-class scholar of ancient philosophy and of Posidonius, in particular. Through his long struggle with the fragments of Posidonius, Kidd has done more than any other scholar of ancient philosophy to dispel the myth of "Pan-Posidonianism." He has presented a clearer picture of the Posidonius to whom we may have access. The bulk of this volume is built around the theme of Kidd's own inaugural lecture at St. Andrews, "The Passionate Intellect." Many of the contributions follow this theme through by examining how individual people and texts influenced the direction of various traditions. Many of the papers naturally concentrate on ancient philosophy and its legacy. Others deal with ancient literary theory, history, poetry, and drama. Most of the papers deal with their subjects at some length and are significant contributions in their own right.
