  There actually seems to be a good deal more support for Albert's view than for Thomas's in the Posterior Analytics. Albert relies in particular on Aristotle's reference to the sort of definition that includes every part of a demonstration, but arranged in a different order (Posterior Analytics II 10), which he takes to be the definition of the passion which is the middle term in a demonstration, and on the examples of demonstration discussed in Posterior Analytics II 8. Aquinas finds little support for his position in the Posterior Analytics, and resorts to De Anima I 1 to prove his point, so that much of his more detailed discussion of demonstration of the highest sort is in fact to be found outside the commentary on the Posterior Analytics.
