abstraction meaning in Etymology Dictionary

c.1400, "a withdrawal from worldly affairs, asceticism," from Old French abstraction (14c.), from Latin abstractionem (nominative abstractio), noun of action from previous participle stem of abstrahere "drag away, distance themself, divert" (see abstract (adj.)). Meaning "idea of something that doesn't have actual presence" is from 1640s.

abstraction meaning in Philosophy Dictionary

(Lat. abdominal, from + trahere, to-draw) The process of essentially separating a partial aspect or high quality from a complete object. In addition the effect or product of emotional abstraction. Abstraction, which concentrates its interest for a passing fancy aspect, is different from analysis which considers every aspect on a par. -- L.W. In logic: offered a connection R which will be transitive, symmetric, and reflexive, we may introduce or postulate "new elements corresponding toward people in the world of R, in such a way the same brand new factor corresponds to two people x and y associated with the industry of R if and only if xRy (understand article connection). These brand-new elements are then reported to be acquired by abstraction pertaining to R. Peano calls this an approach or kind of definition, and speaks, e.g., of cardinal figures (q.v.) as gotten from courses by abstraction with respect to the relation of equivalence -- two classes getting the exact same cardinal number if and only if they're comparable. Offered a formula A containing a totally free adjustable, state x, the entire process of forming a matching monadic function (q.v.) -- defined by the rule that value of the event for a disagreement b usually which A denotes in the event that variable x is taken as denoting b -- is also known as abstraction, or useful abstraction. Within good sense, abstraction is a procedure upon a formula A yielding a function, and it is relative to a specific system of explanation for the notations appearing inside formula, and a certain variable, as x. The necessity that A shall include x as a free variable is not essential: when A does maybe not contain x as a free of charge variable, the function acquired by abstraction relative to x can be taken up to function as function whose price, exactly the same for all arguments, is denoted by A. In articles herein by the current journalist, the notation λx[A] should be useful for the function gotten from A by abstraction in accordance with (or, as we might state, pertaining to) x. Russell, and Whitehead and Russell in Principia Mathematica, employ for this specific purpose the formula A with a circumflex ˆ placed over each (no-cost) incident of x -- but only for propositional features. Frege (1893) uses a Greek vowel, state ε, given that adjustable in accordance with which abstraction is made, and employs the notation ε(A) to denote what is simply the function in expansion (the "Werthverlauf" inside the language) gotten from A by abstraction in accordance with ε. There's also an analogous means of practical abstraction relative to several factors (taken in a given purchase), which yields a polyadic function whenever placed on a formula A. Closely related to the entire process of practical abstraction involves creating a class by abstraction from a suitable formula A relative to a specific variable, state x. The formula recommended be so that (underneath the given system of explanation the notations showing up in A) λx[A] denotes a propositional purpose. After that x∋(A) (Peano), or xˆ (A) (Russell), denotes the class, based on this propositional function. Frege's ε (A) additionally belongs here, if the purpose corresponding to A (reasonably to your variable ε) is a propositional purpose. Similarly, a relation in expansion might be formed by abstraction from the right formula a member of family to two specific factors drawn in a given order. -- A.C. Scholz and Schweitzer, Die sogenannten Definitionen durch Abstraktion, Leipzig, 1935. W. V. Quine, Something of Logistic, Cambridge, Mass., 1934. A. Church, post on the preceding, Bulletin associated with American Mathematical community, vol. 4l (1935), pp. 498-603. W. V. Quine, Mathematical Logic, Ny, 1940. In therapy: the mental operation wherein we continue from people to ideas of classes, from individual dogs toward thought of "the dog." We abstract features common to several people, grouping them therefore collectively under one name. In Scholasticism: the procedure through which the mind becomes cognizant of universal (q.v.) as represented because of the individuals. Aristotle and Thomas ascribe this procedure towards the energetic intellect (q.v.) which "illuminates" the picture (phantasm) and disengages from this the universal nature to be gotten and made intelligible because of the possible intellect. -- R.A.
