## syllogism

(ˈsɪləˌdʒɪzəm)
n
1. (Logic) a deductive inference consisting of two premises and a conclusion, all of which are categorial propositions. The subject of the conclusion is the minor term and its predicate the major term; the middle term occurs in both premises but not the conclusion. There are 256 such arguments but only 24 are valid. Some men are mortal; some men are angelic; so some mortals are angelic is invalid, while some temples are in ruins; all ruins are fascinating; so some temples are fascinating is valid. Here fascinating, in ruins, and temples are respectively major, middle, and minor terms
2. (Logic) a deductive inference of certain other forms with two premises, such as the hypothetical syllogism,if P then Q; if Q then R; so if P then R
3. (Logic) a piece of deductive reasoning from the general to the particular
4. (Logic) a subtle or deceptive piece of reasoning
[C14: via Latin from Greek sullogismos, from sullogizesthai to reckon together, from sul- syn- + logizesthai to calculate, from logos a discourse]

To reconstrue "deductive inference" while "inhabiting" it required dislodging rationalist construals yet keeping the focus on a certain domain of reasoning even while reconfiguring it, roughly, a domain of reasoning where people assess the entailments of assertions, adjudicate contradictory accounts, or evaluate the soundness of arguments.
