re	[in] the matter of	More literally, "by the thing". From the ablative of res ("thing" or "circumstance"). It is a common misconception that the "Re:" in correspondence is an abbreviation for regarding or reply; this is not the case for traditional letters. However, when used in an e-mail subject, there is evidence that it functions as an abbreviation of regarding rather than the Latin word for thing. The use of Latin re, in the sense of "about", "concerning", is English usage.
rebus sic stantibus	with matters standing thus	The doctrine that treaty obligations hold only as long as the fundamental conditions and expectations that existed at the time of their creation hold.
recte et fortiter	Upright and Strong	Motto of Homebush Boys High School
recte et fideliter	Upright and Faithful	Also "just and faithful" and "accurately and faithfully". Motto of Ruyton Girls' School
reductio ad absurdum	leading back to the absurd	A common debate technique, and a method of proof in mathematics and philosophy, that proves the thesis by showing that its opposite is absurd or logically untenable. In general usage outside mathematics and philosophy, a reductio ad absurdum is a tactic in which the logic of an argument is challenged by reducing the concept to its most absurd extreme. Translated from Aristotle's "ἡ εις άτοπον απαγωγη" (hi eis atopon apagogi, "reduction to the impossible").
reductio ad Hitlerum	leading back to Hitler	A term coined by German-American political philosopher Leo Strauss to humorously describe a fallacious argument that compares an opponent's views to those held by Adolf Hitler or the Nazi Party. Derived from reductio ad absurdum.
reductio ad infinitum	leading back to the infinite	An argument that creates an infinite series of causes that does not seem to have a beginning. As a fallacy, it rests upon Aristotle's notion that all things must have a cause, but that all series of causes must have a sufficient cause, that is, an unmoved mover. An argument which does not seem to have such a beginning becomes difficult to imagine. If it can be established, separately, that the chain must have a start, then a reductio ad infinitum is a valid refutation technique.
reformatio in peius	change to worse	A decision from a court of appeal is amended to a worse one. With certain exceptions, this is prohibited at the Boards of Appeal of the European Patent Office by case law.
