Borrowed from French ratiocination, from Latin ratiōcinātiō (“argumentation, reasoning, ratiocination; a syllogism”), from ratiōcinātus (“reckoned”) + -tiō (“suffix forming a noun relating to some action or the result of an action”). Ratiōcinātus is the perfect passive participle of ratiōcinor (“to compute, reckon; to argue, infer”), from ratiō (“reason, explanation”) (from reor (“to calculate, reckon”), possibly from Proto-Italic *rēōr, from Proto-Indo-European *h₂reh₁- (“to put in order”)) + -cinor, modelled after vāticinor (“to foretell, prophesy”), equivalent to ratiocinate + -ion.

- Reasoning, in the extended sense in which I use the term, and in which it is synonymous with Inference, is popularly said to be of two kinds: reasoning from particulars to generals, and reasoning from generals to particulars; the former being called Induction, the latter Ratiocination or Syllogism. […] The meaning intended by these expressions is, that Induction is inferring a proposition from propositions less general than itself, and Ratiocination is inferring a proposition from propositions equally or more general.

- Finally Tao comes to possess the meaning of “rational speech” or “word,” and in this sense it closely resembles the Greek Logos, for in addition to its philosophical significance the term Tao touches a religious chord in the souls of the Chinese just as did the word Logos among the Platonists and the Greek Christians. […] The Tao of man, jan tao [footnote: 人道], is the process of ratiocination, and as such it is fallible; but there is an Eternal Reason, ch‘ang tao [footnote: 常道], also called t‘ien tao [footnote: 天道], “Heaven’s Reason,” i.e., the world-order which shapes all things, and the burden of Lao-tze’s message is to let this Heaven’s Reason or Eternal Reason prevail.
- A proposition arrived at by such thought.

- Where the Qur’an has not been explicit, the Hadith has often supplied guidance, providing an intermediate source of knowledge between the text of the Holy Book itself and the ratiocinations of the religious lawyers, the fuqaha’, who had recourse, when all else failed, to such principles as analogical reasoning and personal judgement.
