The humanist treatises presented here are only peripheral to the history of logic, but I think historians of logic may read them with interest, if perhaps with irritation. In the early sixteenth century the humanists set about to demolish medieval logic based on syllogistic and disputation, and to replace it in the university curriculum with a 'rhetorical' logic based on the use of topics and persuasion. To a very large extent they succeeded. Although Aris totelian logic retained a vigorous life in the schools, it never again attained to the overwhelming primacy it had so long enjoyed in the northern universities. It has been the custom to take the arguments of the humanists at face value, and the word 'scholastic' has continued to have pejorative overtones. This is easy to understand, because until recently our knowledge of the high period of medieval logic has been slight, and the humanists' testimony as to its decadent state in the sixteenth century has, for the most part, been accepted uncritically. Within the past two decades important work on medieval logic has recovered the brilliant achievement of thirteenth and fourteenth century logicians, philosophers, and natural scientists. New studies are constantly appearing, and the logico-semantic system of the terminists has become fruitful territory not only for historians of logic but also for students of modern linguistics and semiotics."

The Latin texts collected by Leon Baudry present the late fifteenth century debate at the University of Louvain over the truth-value of proposi tions about future contingent events, a subject of perennial interest in phil osophy. The theologians held fast to divine predetermination, and the Aristotelians in the Arts Faculty supported the doctrine of free choice based on indeterminism. Although the issues in the debate are still argued in philosophy, this rich collection of the theories and arguments has been neglected. Peter de Rivo and Henry de Zomeren, the principal antagonists, are cited in the recent literature, but only on the basis of slight, mostly second-hand information. The full collection of texts has never before been translated into English (or any other modern language), leaving them inaccessible to the majority of students, or any others who are not equipped to work their way through 450 pages of fifteenth-century scholastic Latin. Apart from their philosophical significance, the texts shed light on late scholastic methods in teaching and disputation, on university politics of the period in relation to the Vatican, the Court of the Duke of Burgundy, and the faculties of other great universities, and on legal procedures both secular and ecclesiastical. The human drama that develops as the debate proceeds should hold the interest of even the non-specialist."
