Editing Sum of Logic (section)

===Part III.  On Consequences===

* The first 37 chapters of Part II are a systematic exposition of Aristotle's [[Topics (Aristotle)|Topics]].  In Part III, Ockham deals with the definition and division of consequences, and provides a treatment of Aristotle's Topical rules.<ref>Boehner p.54</ref>  According to Ockham a consequence is a [[conditional sentence|conditional proposition]], composed of two categorical propositions by the terms 'if' and 'then'. For example, 'if a man runs, then God exists' (''Si homo currit, Deus est'').<ref>Boehner pp. 54–5</ref>  A consequence is 'true' when the [[antecedent (logic)|antecedent]] implies the [[consequent]]. Ockham distinguishes between 'material' and 'formal' consequences, which are roughly equivalent to the modern [[Material conditional|material implication]] and [[Logical consequence|logical implication]] respectively.  Similar accounts are given by [[Jean Buridan]] and [[Albert of Saxony (philosopher)|Albert of Saxony]].
* Chapters 38 to 45 deal with the [[Theory of obligationes]].
*Chapter 46 deals with the [[Liar paradox|Liar Paradox]]
