     integrity, fidelity, and other gracious plausibilities

   • 1790, Mary Wollstonecraft, A Vindication of the Rights of Men‎:

     Plausibility, I know, can only be unmasked by shewing the absurdities it glosses over, and the simple truths it involves with specious errors.

3. A plausible statement, argument etc. [from 17th c.]
   • 1869, Robert Browning, “XI. Guido.”, in The Ring and the Book. […], volume IV, London: Smith, Elder and Co., →OCLC, page 164, lines 1680–1681 and 1685–1687:

     She too must shimmer through the gloom o' the grave, / Come and confront me— […] / Striking me dumb, and helping her to speak, / Tell her own story her own way, and turn / My plausibility to nothingness!

4. (now in more positive sense) The fact of being believable; believability, credibility. [from 18th c.]

     The question of the plausibility of the counter-factual is seen as key in all three discussions of allohistorical fiction (as it is in Demandt's and Ferguson's examinations of allohistory) (cf. Rodiek 25–26; Ritter 15–16; Helbig 32).
