Concept
A concept is a mental symbol, used to denote a class of things in the world. Concepts are mental representations that allows us to draw appropriate inferences about the type of entities we encounter in our everyday lives. Concepts do not encompass all mental representations, but are merely a subset of them. Concepts are the glue that bind entities in the world, and are distinct from 'conceptions', which are the beliefs that we hold about these entities. The use of concepts is necessary to cognitive processes such as categorization, memory, decision making, learning and inference.

Famous quotes containing the word concept:
“It is impossible to dissociate language from science or science from language, because every natural science always involves three things: the sequence of phenomena on which the science is based; the abstract concepts which call these phenomena to mind; and the words in which the concepts are expressed. To call forth a concept, a word is needed; to portray a phenomenon, a concept is needed. All three mirror one and the same reality.”
—Antoine Lavoisier (1743–1794)
“The latest creed that has to be believed
And entered in our childish catechism
Is that the All’s a concept self-conceived,
Which is no more than good old Pantheism.”
—Robert Frost (1874–1963)
“The heritage of the American Revolution is forgotten, and the American government, for better and for worse, has entered into the heritage of Europe as though it were its patrimony—unaware, alas, of the fact that Europe’s declining power was preceded and accompanied by political bankruptcy, the bankruptcy of the nation-state and its concept of sovereignty.”
—Hannah Arendt (1906–1975)
