Abstraction Wikipedia. Abstraction in its main sense is a conceptual process where 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 processa concept that acts as a super categorical 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 the 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, eliminating the other characteristics of that particular ball. In a typetoken distinction, a type e. Abstraction in its secondary use is a material process,2 discussed in the themes below. OriginseditThinking in abstractions is considered by anthropologists, archaeologists, and sociologists to be one of the key traits in modern human behaviour, which is believed to have developed between 5. Its development is likely to have been closely connected with the development of human language, which whether spoken or written appears to both involve and facilitate abstract thinking. HistoryeditAbstraction involves induction of ideas or the synthesis of particular facts into one general theory about something. It is the opposite of specification, which is the analysis or breaking down of a general idea or abstraction into concrete facts. Abstraction can be illustrated with Francis Bacons Novum Organum 1. Elizabethan era3 of England to encourage modern thinkers to collect specific facts before making any generalizations. Bacon used and promoted induction as an abstraction tool, and it countered the ancient deductive thinking approach that had dominated the intellectual world since the times of Greek philosophers like Thales, Anaximander, and Aristotle. Thales c. 6. 245. BCE believed that everything in the universe comes from one main substance, water. He deduced or specified from a general idea, everything is water, to the specific forms of water such as ice, snow, fog, and rivers. Modern scientists can also use the opposite approach of abstraction, or going from particular facts collected into one general idea, such as the motion of the planets Newton 1.

CompressioneditAn abstraction can be seen as a compression process,4 mapping multiple different pieces of constituent data to a single piece of abstract data 5 based on similarities in the constituent data, for example, many different physical cats map to the abstraction CAT. This conceptual scheme emphasizes the inherent equality of both constituent and abstract data, thus avoiding problems arising from the distinction between abstract and concrete. In this sense the process of abstraction entails the identification of similarities between objects, and the process of associating these objects with an abstraction which is itself an object. For example, picture 1 below illustrates the concrete relationship Cat sits on Mat. Chains of abstractions can be construed,6 moving from neural impulses arising from sensory perception to basic abstractions such as color or shape, to experiential abstractions such as a specific cat, to semantic abstractions such as the idea of a CAT, to classes of objects such as mammals and even categories such as object as opposed to action. For example, graph 1 below expresses the abstraction agent sits on location. This conceptual scheme entails no specific hierarchicaltaxonomy such as the one mentioned involving cats and mammals, only a progressive exclusion of detail. InstantiationeditNon existent things in any particular place and time are often seen as abstract. By contrast, instances, or members, of such an abstract thing might exist in many different places and times. Those abstract things are then said to be multiply instantiated, in the sense of picture 1, picture 2, etc., shown below.

Doing so would make the concepts cat and telephone abstract ideas since despite their varying appearances, a particular cat or a particular telephone is an instance of the concept cat or the concept telephone. Although the concepts cat and telephone are abstractions, they are not abstract in the sense of the objects in graph 1below. Indecision and delays are the parents of failure.

We might look at other graphs, in a progression from cat to mammal to animal, and see that animal is more abstract than mammal but on the other hand mammal is a harder idea to express, certainly in relation to marsupial or monotreme. Perhaps confusingly, some philosophies refer to tropes instances of properties as abstract particularse. This is similar to qualia and sumbebekos. Material processeditStill retaining the primary meaning of abstrere or to draw away from, the abstraction of money, for example, works by drawing away from the particular value of things allowing completely incommensurate objects to be compared see the section on Physicality below. Karl Marxs writing on the commodity abstraction recognizes a parallel process. The state polity as both concept and material practice exemplifies the two sides of this process of abstraction. Conceptually, the current concept of the state is an abstraction from the much more concrete early modern use as the standing or status of the prince, his visible estates. At the same time, materially, the practice of statehood is now constitutively and materially more abstract than at the time when princes ruled as the embodiment of extended power. Ontological statuseditThe way that physical objects, like rocks and trees, have being differs from the way that properties of abstract concepts or relations have being, for example the way the concrete, particular, individuals pictured in picture 1 exist differs from the way the concepts illustrated in graph 1 exist. That difference accounts for the ontological usefulness of the word abstract.

PhysicalityeditA physical object a possible referent of a concept or word is considered concrete not abstract if it is a particular individual that occupies a particular place and time. However, in the secondary sense of the term abstraction, this physical object can carry materially abstracting processes. For example, record keeping aids throughout the Fertile Crescent included calculi clay spheres, cones, etc. According to Schmandt Besserat 1. The containers thus served as something of a bill of lading or an accounts book. In order to avoid breaking open the containers for the count, marks were placed on the outside of the containers.
