The '''''Summa Logicae''''' ("Sum of Logic") is a textbook on [[logic]] by [[William of Ockham]]. It was written around 1323.
{{Scholasticism}}
Systematically, it resembles other works of medieval logic, organised under the basic headings of the [[Aristotelianism|Aristotelian]] [[Predicable]]s, [[Category of being|Categories]], [[terminology|terms]], [[proposition]]s, and [[syllogism]]s.  These headings, though often given in a different order, represent the basic arrangement of scholastic works on logic.

This work is important in that it contains the main account of Ockham's [[nominalism]], a position related to the [[problem of universals]].
