Sic et Non, an early
scholastic text whose title translates from
Medieval Latin as "Yes and No", was written by
Pierre Abélard. In the work, Abélard juxtaposes apparently contradictory quotations from the
Church Fathers on many of the traditional topics of
Christian theology. In the Prologue, Abélard outlines rules for reconciling these contradictions, the most important of which is noting the multiple significations of a single word. However, Abélard does not himself apply these rules in the body of the
Sic et non, which has led scholars to conclude that the work was meant as an exercise book for students in applying dialectic (logic) to theology.
