YOF LOGIC : OR, 111E RIGHT'öSE DF REASON. four of them are excluded from forming true syllogisms by''the seven rules in the foregoing section ; the remaining ten are va- riously diversified by figures and moods into fourteen syllogisms. The figure of a syllogism is the proper disposition of the middle term with the parts of the question. A mood is the regular determination of propositions accord ing to their quantity and quality, that is, their universal or par- ticular affirmation or negation ; which are signified by certain artificial words wherein the consonants are neglected, and these four vowels, A, E, I, O, are only regarded. There are generally counted three figures. In the first of them the middle term is the subject of the major proposition, and the predicate of the minor. This contains four moods, called, Barbara, Celarent, Darii, Ferio. And it is the excellency of this figure, that all sorts of questions or conclusions may be proved by it, whether A, E, I, or O, that is, universal or parti- cular, affirmative or negative; as, Bar -Every wicked man is truly miserable ; ba -All tyrants are wicked men ; ra. Therefore all tyrants are truly miserable. Ce -He that's always in fear is not happy ; /a-Covetous men are always in fear ; rent. Therefore covetous men are not happy. Da- Whatsoever furthers our salvation is good for us; ri -Some afflictions further our salvation ; i. Therefore some afflictions are good for us. Fe-Nothing that must be repented of is truly desirable; ei Some pleasures must be repented of; o. Therefore there arc some pleasures which are not truly desirable. In the second figure the middle term is the predicate of both the premises : this contains four moods, namely, Cesare, Camestres, Festino, Baroca, and it admits only of negative con- clusions ; as, Ce -No liar is fit to be believed ; sa -Every good christian is fit to be believed ; re. Therefore no good christian is a liar. The reader may easily form examples of the rest. The third figure requires that the middle term be the sub- ject of both ttié premises. It has six moods, namely, Darapti, Felapton, Disantis, Datasi, Bocardo, Ferison i and it admits only of particular conclusions ; as, Da- Whosoever loves God shall be saved ; rap -All the lovers of God have their imperfections ; ti. Therefore some who have imperfections shall be saved.
