Encyclopedic and philosophical literature establishes that concepts serve as foundational cognitive units and constituents of thoughts, making it possible to form and combine ideas, thereby distinguishing between ideas and concepts.

Concepts are fundamental units of cognition through which individuals understand the world. They make it possible to form and combine ideas, classify things, draw inferences, grasp the meanings of words, and refer to external entities. Concepts are often understood as abstract representations or ideas that different people can share. They encode common features of objects and events, grouping individual things into categories. For example, the concepts car, teacher, and prime number encode information about their respective kinds, conveying what members of each group have in common. Concepts are involved in many mental processes, including perception, memory, reasoning, learning, and decision-making. They are relevant to several fields of inquiry, such as philosophy, psychology, linguistics, and cognitive science. Their exact definition is disputed and varies by discipline.
The intension of a concept is its sense or the features it encodes. The extension of a concept is the set of all entities to which it refers. A concept is typically a general entity that applies to many different things. For example, the concept city refers to New York, Paris, Tokyo, and many others. Philosophers also discuss singular concepts, which refer only to a single entity, such as the concept of the planet Mars. There are also empty concepts without real-world instances, like the concept unicorn.
Concepts are components of thought but not fully formed thoughts: they are subpropositional units, like the concept baby, that do not amount to complete propositions, like the statement "the baby is sleeping". Accordingly, concepts apprehend the character of something without asserting or negating anything about it. Concepts are further distinguished from nonconceptual contents—mental representations that do not require concept possession. Raw sense data, such as colors, shapes, and sounds, are often discussed as examples of nonconceptual contents. According to this view, perception contains more information than what is conceptually grasped. For example, a person may visually distinguish differences between similar shades of red despite lacking distinct concepts for each shade.
Concepts are closely related to language and are often characterized as the meanings of words. However, they are not identical to words: different words can express the same concept, and a single word can have several meanings. It is possible to learn a word without knowing its meaning and to possess a concept without knowing a word for it. Conceptual capacities are primarily associated with humans, but in a broader sense, they are also attributed to some nonhuman animals.
In contrast to the theory theory, conceptual or informational atomism rejects the holistic outlook. It asserts that lexical concepts are simple units that do not depend on each other. Accordingly, the concept cow does not depend on theories about cows or on cow-related concepts. It is simply defined through its referents: the cows to which it refers. In this sense, lexical concepts lack internal structure. This view maintains that knowledge about the relations among lexical concepts is built on concepts but is not an essential part of them. Conceptual atomism holds that besides lexical concepts, there are also complex concepts, which have an internal structure constructed from simpler concepts.
Pluralist or hybrid approaches seek to resolve disagreements between other theories by combining them. According to one proposal, each concept has multiple structures that serve different roles. For instance, the prototype structure supports fast and similarity-based categorization, while the theory-like structure supports slow and reflective reasoning. A different view suggests that the different structures belong to distinct concepts. Accordingly, people form several competing concepts for each category. For example, a person may have multiple cat concepts, such as a prototype-based cat concept alongside a theory-based cat concept.
Neuroscientists examine how concepts are stored and used in the brain. Among other things, they explore which brain regions encode concepts and how damage to specific areas influences conceptual activities. A key research method is the use of neuroimaging techniques, such as functional magnetic resonance imaging (fMRI), to study region-specific brain activity, often combined with behavioral analyses to link neural activation patterns with task performance.
Researchers in computer science and artificial intelligence are interested in concepts as formal structures involved in knowledge representation and automated reasoning. They treat concepts as models used to categorize entities and encode information about them. To describe systems with many entities, they employ formal ontologies, such as the Suggested Upper Merged Ontology, which are comprehensive conceptual hierarchies that formalize relationships between concepts. The field of machine learning investigates algorithms that can generalize data from training sets to create and employ novel models of concepts. Cognitive science integrates ideas from psychology, philosophy, linguistics, neuroscience, and computer science to develop unified models of cognition and the role of concepts within it.
Conceptual history is a form of intellectual history that examines the development of concepts and ideas. It typically focuses on fields like science,
What are ideas for Spinoza? Through a discussion of the definition of “idea” in 2def3, it is shown, first, that Spinoza is reacting here to both Hobbes’ objections to the Meditations and Descartes’ replies. While he agrees with Hobbes that ideas are conceptions that are formed, rather than merely perceived, by the human mind, he sides with Descartes regarding the irreducibly mental character of ideas. With respect to the issue of mental content, the chapter next argues that Spinoza not only distinguishes between formal and objective reality but also assumes that objective reality comprises two aspects, representational content and epistemic value. This is one reason why Spinozistic ideas have proved notoriously difficult to clearly individuate. Lastly, through an examination of how Spinoza employs Descartes’ Pegasus example, the case is made that, far from simply elaborating on Descartes’ approach, Spinoza dismisses Cartesian nativism as a basis for his rationalism.
