Editing Syllogism (section)

====Peter Abelard====

Another of medieval logic's first contributors from the Latin West, [[Peter Abelard]] (1079–1142), gave his own thorough evaluation of the syllogism concept, and accompanying theory in the ''Dialectica''—a discussion of logic based on Boethius' commentaries and monographs. His perspective on syllogisms can be found in other works as well, such as ''Logica Ingredientibus''. With the help of Abelard's distinction between ''[[de dicto]]'' modal sentences and ''[[de re]]'' modal sentences, medieval logicians began to shape a more coherent concept of Aristotle's modal syllogism model.
