These 3 showed up in a brief block of paragraphs in a book I'm glomming lately, Techniques of Fiction Writing (Measure and Madness).
Peripety - n. - a sudden and unexpected change of fortune or reverse of circumstances (especially in a literary work); "a peripeteia swiftly turns a routine sequence of events into a story worth telling"
Anagnorisis - n pl -ses [-ˌsiːz] (Literary & Literary Critical Terms) (in Greek tragedy) the recognition or discovery by the protagonist of the identity of some character or the nature of his own predicament, which leads to the resolution of the plot; denouement [from Greek: recognition]
Syllogistic >
Syllogism
1. (Philosophy / 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. (Philosophy / 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. (Philosophy / Logic) a piece of deductive reasoning from the general to the particular
4. (Philosophy / Logic) a subtle or deceptive piece of reasoning [via Latin from Greek sullogismos, from sullogizesthai to reckon together, from sul- syn- + logizesthai to calculate, from logos a discourse]
[Middle English silogisme, from Old French, from Latin syllogismus, from Greek sullogismos, from sullogizesthai, to infer : sun-, syn- + logizesthai, to count, reckon (from logos, reason; see leg- in Indo-European roots).]
