Quantum Theory

(1,290 words)

Author(s): Baak, David A. Van
“Quantum theory” is the term for a collection of physical theories about the behavior of matter, all of which are distinguished from previous Newtonian theory by their acceptance of ¶ discrete or discontinuous behavior of matter, and by their supplanting of Newtonian determinism in favor of a probabilistic description of material reality. 1. The Quantum Principle The mechanical theory of mass, force, and motion ascribed to Isaac Newton (1642–1727) yields a picture of the world in which the physical variables describing an isolated system (such as pos…

Quaternity

(423 words)

Author(s): Colpe, Carsten
The number four ranks high among the symbolically significant numbers (Symbol). In translations of Monophysite arguments both for and against Apollinarius of Laodicea (d. ca. 390), theological Latin refers to quaternitas along with trinitas. “Two natures,” it was argued, means “two sons,” and hence we have a tetrad instead of a triad (Trinity). In religious history the term “quaternity” denotes a fourfold structure. On the basis, for example, of the four points of heaven, the four ages, the four sides of a square, the four temperaments, the four…

Quietism

(390 words)

Author(s): Frey, Christofer
“Quietism” is the term used for a mystically oriented, transdenominational movement in the 17th and 18th centuries (Mysticism 2). Two of its main features find expression in 18th-century Protestant poetry (Devotional Literature), namely, silence and simplicity, as in G. Tersteegen’s “Gott ist gegenwärtig … alles in uns schweige” (God is present, [let] everything in us be silent) and M. Claudius’s “Laß uns einfältig werden” (Let us become simple). From the standpoint of social history quietism ma…

Qur’ān

(2,857 words)

Author(s): Allen, Roger
1. Etymology Arab. Qur’ān (often previously transliterated “Koran”) is a derivative of the verbal root qrʾ, with the general meaning “recite (orally).” The imperative of the same verb, iqraʾ, is generally acknowledged to be the opening of the first utterance revealed by God to the Prophet Muḥammad, in sūrah 96 (The Blood-Clot), v. 1, and is God’s command to Muḥammad that he proclaim God’s revelations. Qur’ān is thus best translated “recitation.” This etymology is of importance because it underlines both the oral origins of Islam’s most authoritative source an…
