§ 744. Such syllogisms as those just treated of, if syllogisms they are to be called, have a major and a middle term visible to the eye, but appear to be destitute of a minor. The missing minor term is however supposed to be latent in the transition from the conjunctive to the simple form of proposition. When we say 'A is B,' we are taken to mean, 'As a matter of fact, A is B' or 'The actual state of the case is that A is B.' The insertion therefore of some such expression as 'The case in hand,' or 'This case,' is, on this view, all that is wanted to complete the form of the syllogism. When reduced in this manner to the simple type of argument, it will be found that the constructive conjunctive conforms to the first figure and the destructive conjunctive to the second. _Constructive Mood_. _Barbara_. If A is B, C is D. \ / All cases of A being B are cases of \ = / C being D. A is B. / \ This is a case of A being B. .'. C is D. / \ .'. This is a case of C being D. _Destructive Mood._ Camestres. If A is B, C is D. \ / All cases of A being B are cases of \ = / C being D. C is not D. / \ This is not a case of C being D. .'. A is not B. / \ .'. This is not a case of A being B. § 745. It is apparent from the position of the middle term that the constructive conjunctive must fall into the first figure and the destructive conjunctive into the second. There is no reason, however, why they should be confined to the two moods, Barbara and Carnestres. If the inference is universal, whether as general or singular, the mood is Barbara or Carnestres; if it is particular, the mood is Darii or Baroko. Barbara. Camestres.

The remaining moods of the first and second figure are obtained by taking a negative proposition as the consequent in the major premiss. Celarent. Ferio. If A is B, C is never D.
