ABSTRACTION (See also:Lat. abs and trahere) , the See also:process or result of See also:drawing away; that which is See also:drawn away, separated or derived. Thus the noun is used for a See also:summary, compendium or See also:epitome of a larger See also:work, the gist of which is given in a concentrated See also:form. Similarly an absent-minded See also:man is said to be " abstracted," as paying no See also:attention to the See also:matter in See also:hand. In See also:philosophy the word has several closely related technical senses. (s) In formal See also:logic it is applied to those terms which denote qualities, attributes, circumstances, as opposed to See also:concrete terms, the names of things; thus " friend " is concrete, " friendship " abstract. The See also:term which expresses the See also:connotation of a word is therefore an abstract term, though it is probably not itself connotative; adjectives are concrete, not abstract, e.g. " equal " is concrete, " equality " abstract (cf. See also:Aristotle's aphaeresis and prosthesis). (2) The process of abstraction takes an important See also:place both in psychological and metaphysical See also:speculation. The psychologist finds among the earliest of his problems the question as to the process from the See also:perception of things seen and heard to See also:mental conceptions, which are ultimately distinct from immediate perception (see See also:PSYCHOLOGY). When the mind, beginning with isolated individuals, See also:groups them together in virtue of perceived resemblances and arrives at a unity in See also:plurality, the process by which attention is diverted from individuals and concentrated on a single inclusive concept (i.e. See also:classification) is one of abstraction. All orderly thought and all increase of knowledge depend partly on establishing a clear and accurate connexion between particular things and See also:general ideas, rules and principles.

The nature of the resultant concepts belongs to the See also:

great controversy between See also:Nominalism, See also:Realism and See also:Conceptualism. See also:Meta-physics, again, is concerned with the ultimate problems of matter and spirit; it endeavours to go behind the phenomena of sense and See also:focus its attention on the fundamental truths which are the only logical bases of natural See also:science. This, again, is a process of abstraction, the attainment of abstract ideas which, apart from the concrete individuals, are conceived as having a substantive existence. The final step in the .process is the conception of the See also:Absolute (q.v.), which is abstract in the most See also:complete sense. Abstraction differs from See also:Analysis, inasmuch as its See also:object is to select a particular quality for See also:consideration in itself as it is found in all the See also:objects to which it belongs, whereas analysis considers all the qualities which belong to a single object.
