Monitio logica, or, An abstract and translation of Burgersdicius his logick by a gentleman.

CHAP. X. Now of finding out a Medium, with Propriety to each Figure and Mode.

Ax. 1. THE Medium may be compared with the Parts of the Question, either as An∣tecedent, Consequent, or Repugnant.

Ax. 2. The Medium is said to be Antecedent, when in an Affirming Enunciation it is subjected; Consequent when predicated; Repugnant, when either subjected or predicated in an Enunciation Denying.

1. §. And hence it will be easie to guess what kind of Medium each Mood and Figure requires: In Barbara and Darii, the Medium is the Antece∣dent of the Predicate, and Consequent of the Sub∣ject: In Celarent, Ferio, Cesare, Festino, repugnant of the Predicate, and Consequent of the Subject: Ca∣mestres and Baroco, Consequent of the Predicate, and Repugnant of the Subject: Darapti, Disamis and Da∣tisi Antecedent of Both: In Felapton, Bocardo and Fe∣rison, repugnant of the Predicate, and Antecedent of the Subject. If the Medium be the Consequent of the Predicate, and Antecedent of the Subject, the

Syllogism will be indirect in the First, viz. vulgar∣ly the fourth Figure. If repugnant of both a Pa∣rallogism, and that of two Negatives; if of the Pre∣dicate Antecedent, and Consequent of the Subject: So, by reason of the Minor denying in the first or third Figure. If lastly, Consequent of both, one of the two Affirmatives in the second Figure.

2 §. All which is taught in these few Words which are contained in this Distich.

By Napcas, Nipcis, or Nipis, Repcere Cepres, And Ropcos, Copros, Nosrop, you'll find every Me∣dium.

In which Versicles are to be considered, First, the Vowels A, E, I, O, which denote the Quality and Quantity of the Conclusion according to the accustomed Valuation. And then the Consonants N, C, R, S, P. Of which N denotes the Antecedent, C the Conse∣quent, R the Repugnant, S the Subject, P the Predi∣care, &c. And therefore if a Universal Conclusion Af∣firming be to be proved, Napcas will shew by its Con∣sonants N, P, C, S. that a Medium is required, which is Amtecedent of the Predicate and Consequent of the Subject; and if a Particular Affirming: Nipcis, that there is need of a Medium, that is Antecedent of the Predicate also, and Consequent of the Sub∣ject: Nipis Antecedent of both. If a Universal de∣nying, the Word Repcere shews that the Medium ought to be Repugnant of the Predicate and Consequent of the Subject; and so by the Confonants, minding only what it is they signifie, it will be easie for a Practi∣ser to whom this is principally significant, to determine of the rest.

3. For our Example; be this vulgar Probleme, Is Pleasure good? Seek first the Consequences of the Predicate, viz. to be Chosen, Conducible, &c. then the Antecedents, as, Febicity, Sanity, &c. then the Repugnants, at, to be

avoided, turpid, &c. Seek also the Consequences of the Subject, as Peaceable, according to Nature. Then the Antecedents, as Pleasure of Musick, &c. Lastly, the Repugnants, as, what is molestous, laborious, &c. Make we now a Universal Conclusion after this man∣ner. All Pleasure is good. This is found only in Napcas, as being the Word which indicates the Me∣dium to he the Antecedent of the Predicate, and Con∣sequent of the Subject. Take we, for Instance the Me∣dium, according to Nature: And the Syllogism will be this in Barbara, Whatever is according to Na∣ture, is good; but all Pleasure is according to Nature: And therefore all Pleasure is good, &c. If, we were to conclude, Some Pleasure is good, then accord∣ing to the Word Nipcis, the Antecedent of both of them were to be taken: As, suppose Musical Pleasure, and then the Syllogism would be in Darapti, Disamis, or Datisi: As this; All Musical Pleasure is good; All Musical Pleasure is Pleasure: Some Pleasure therefore is good, &c.

But thus much of a Medium, as it has Re∣ference to each Figure and Mode; in another Capacity, we shall consider it hereafter. We come now to the Species's of Syllogism, and First speak we of Induction, Enthymeme, and Example.
