Abstraction

·adj Absence or absorption of mind; inattention to present objects.

II. Abstraction ·adj A separation from worldly objects; a recluse life; as, a hermit's abstraction.

III. Abstraction ·adj A separation of volatile parts by the act of Distillation.

IV. Abstraction ·adj The taking surreptitiously for one's own use part of the property of another; purloining.

V. Abstraction ·adj An idea or notion of an abstract, or theoretical nature; as, to fight for mere abstractions.

VI. Abstraction ·adj The act of abstracting, separating, or withdrawing, or the state of being withdrawn; withdrawal.

VII. Abstraction ·adj The act process of leaving out of consideration one or more properties of a complex object so as to attend to others; analysis. Thus, when the mind considers the form of a tree by itself, or the color of the leaves as separate from their size or figure, the act is called abstraction. So, also, when it considers whiteness, softness, virtue, existence, as separate from any particular objects.

abstraction

1. Generalisation; ignoring or hiding details to capture some kind of commonality between different instances. Examples are abstract data types (the representation details are hidden), abstract syntax (the details of the concrete syntax are ignored), abstract interpretation (details are ignored to analyse specific properties). 2. <programming> Parameterisation, making something a function of something else. Examples are lambda abstractions (making a term into a function of some variable), {higher-order functions} (parameters are functions), bracket abstraction (making a term into a function of a variable). Opposite of concretisation. (1998-06-04)

Abstraction

Abstraction in its main sense is a conceptual process wherein general rules and concepts are derived from the usage and classification of specific examples, literal ("real" or "concrete") signifiers, first principles, or other methods.

"An abstraction" is the outcome of this process—a concept that acts as a common noun for all subordinate concepts and connects any related concepts as a group, field, or category.

Conceptual abstractions may be formed by filtering the information content of a concept or an observable phenomenon, selecting only those aspects which are relevant for a particular purpose. For example, abstracting a leather soccer ball to the more general idea of a ball selects only the information on general ball attributes and behavior, excluding but not eliminating the other phenomenal and cognitive characteristics of that particular ball. In a type–token distinction, a type (e.g., a 'ball') is more abstract than its tokens (e.g., 'that leather soccer ball').

Abstraction in its secondary use is a material process, discussed in the themes below.
