Those abstract things are then said to be multiply instantiated, in the sense of picture 1, picture 2, etc., shown below. It is not sufficient, however, to define abstract ideas as those that can be instantiated and to define abstraction as the movement in the opposite direction to instantiation. Doing so would make the concepts "cat" and ...
In philosophy and the arts, a fundamental distinction exists between abstract and concrete entities. While there is no universally accepted definition, common examples illustrate the difference: numbers, sets, and ideas are typically classified as abstract objects, whereas plants, dogs, and planets are considered concrete objects.
A representation of the concept of a tree. The four upper images of trees can be roughly quantified into an overall generalization of the idea of a tree, pictured in the lower image. A concept is an abstract idea that serves as a foundation for more concrete principles, thoughts, and beliefs. [1]
Ideation is the creative process of generating, developing, and communicating new ideas, where an idea is understood as a basic unit of thought that can be either visual, concrete, or abstract. [1] Ideation comprises all stages of a thought cycle, from innovation, to development, to actualization. [2]
An example of a mental construct is the idea of class, or the distinguishing of two groups based on their income, culture, power, or some other defining characteristic(s). An operational definition specifies concrete, replicable procedures that reliably produce a differentiated, measurable outcome. Similarly, concepts can remain abstract or can ...
Abstraction in mathematics is the process of extracting the underlying structures, patterns or properties of a mathematical concept, removing any dependence on real world objects with which it might originally have been connected, and generalizing it so that it has wider applications or matching among other abstract descriptions of equivalent phenomena.
The idea is that such changes are not supposed to have any impact on client code, since they involve no difference in the abstract behaviour. For example, one could define an abstract data type called lookup table which uniquely associates keys with values , and in which values may be retrieved by specifying their corresponding keys.
Regulative ideas, for example, are ideals that one must tend towards, but by definition may not be completely realized as objects of empirical experience. Liberty, according to Kant, is an idea whereas "tree" (as an abstraction covering all species of trees) is a concept.
