Abelard's Dialectica was probably written before 1117, possibly 1118-19, based on lectures he gave in Paris 1115-16, around the beginning of his affair with Heloise. It is an independent treatise in logic divided into five parts

  1. De partibus orationis: Aristotle's categories and parts of speech, only the second part of which is extant (De Rijk, 51-145)
  2. De propositionibus et syllogismis categoricis: categorical propositions and syllogisms (ibid 145-249)
  3. Topica: the rules of inference or "topics" (ibid 253-468)
  4. De propositionibus et syllogismis hypotheticis: hypothetical propositions and syllogisms (ibid 469-531)
  5. Liber divisionum et definitionum: division and definition (ibid 532-572)

The only known witness is Paris. B. Nat. lat. 14614, missing the beginning and perhaps the end of the work as well[1].
