	\|		\| Although it was said above <ref>Supra [[../Chapter_10\|c.10]], lin. 5-15; see the variant reading there at lin. 82. </ref> that it is not possible to argue from affirmatives in the second figure, nevertheless there are two cases of exception from that general rule. The first is if the middle term is a discrete term: for then it is possible to infer an affirmative conclusion from two affirmatives; as it follows well ‘every man is Socrates; Plato is Socrates; therefore Plato is man’. And such a syllogism can be proved, because with the propositions reversed it will be an expository syllogism in the third figure.

	\|		\| The second case is when the middle term is taken with a universal sign: for then it is always possible to infer an affirmative conclusion in which the major extreme is predicated of the minor <ref The scribe of codex D here notes in the margin: ‘This proof does not necessarily follow’.</ref>.

For, having converted the major ‘every musician is every man’ into the syllogism ‘every man is a musician’, the syllogism will be regulated by dici de omni (to be said of all) in the first figure, thus arguing ‘every man is a musician; Socrates is a man; therefore Socrates is a musician’.
