Lakoff and Johnson: abstract thought structured by metaphorical mappings from embodied experience.

Conceptual Metaphor Theory (CMT) is the cognitive linguistic framework articulated by George Lakoff and Mark Johnson in their 1980 Metaphors We Live By, holding that abstract concepts are systematically structured by metaphorical mappings from concrete, embodied source domains to abstract target domains — and that metaphor is therefore not merely linguistic decoration but fundamental to thought itself. The framework's central claim: ordinary expressions like 'I see your point,' 'a heated argument,' 'time is money,' 'spending the day' aren't dead metaphors or mere figures of speech but reflect systematic conceptual mappings (UNDERSTANDING IS SEEING, ARGUMENT IS WAR, TIME IS MONEY, TIME IS A RESOURCE) that structure how speakers reason about abstract domains. Lakoff and Johnson identified substantial systematic metaphors including: orientational metaphors (HAPPY IS UP, SAD IS DOWN); structural metaphors (LOVE IS A JOURNEY, ARGUMENT IS A BUILDING, IDEAS ARE FOOD); ontological metaphors (THE MIND IS A CONTAINER, THE MIND IS A MACHINE). Each metaphor highlights certain aspects of the target domain while hiding others — ARGUMENT IS WAR makes adversarial features salient and cooperative features less so. The framework substantially shaped cognitive linguistics, with extensive subsequent development including Lakoff's substantial work on political metaphor (Moral Politics 1996, Don't Think of an Elephant 2004), Johnson and Lakoff's Philosophy in the Flesh (1999) extending CMT into philosophy of mind, Joseph Grady's primary metaphor theory (1997) connecting CMT to embodied experience, and substantial subsequent psychology and neuroscience research on embodied cognition. The framework has produced substantial empirical work (priming studies, gesture analysis, neural correlates) supporting some metaphorical-mapping claims while substantially complicating others. Critics including Steven Pinker have argued CMT overstates the systematicity of metaphorical thought and underweights the literal-conceptual foundation that metaphor maps from.

Core components

Metaphorical mappings from concrete source to abstract target domains
Systematic conceptual metaphors structuring thought
Three types: orientational (HAPPY IS UP), structural (ARGUMENT IS WAR), ontological (MIND IS CONTAINER)
Highlighting and hiding (each metaphor emphasizes some features, downplays others)
Connection to embodied experience and cognition
Foundation for cognitive linguistics
Lakoff's political-metaphor extensions
Joseph Grady's primary metaphor theory
Conceptual blending (Fauconnier-Turner) as related extension
Substantial neuroscience and psychology research on embodied cognition

Primary use case

Foundational framework in cognitive linguistics; basis for substantial work on metaphor in language, thought, and culture; reference framework in cognitive linguistics and cognitive science education; foundation for substantial discourse analysis (political discourse, scientific discourse, religious discourse); integration with broader cognitive science of language; pedagogical foundation in cognitive linguistics curricula; influence on rhetorical analysis, communication theory, advertising analysis; substantial application to second-language acquisition and cross-cultural communication; foundation for some commercial framing-analysis and political-communication consulting (Lakoff's substantial influence on Democratic political messaging).

Common criticisms

Substantial subsequent debate about whether CMT overstates the systematicity of metaphorical thought — Steven Pinker (How the Mind Works 1997, The Stuff of Thought 2007) and others have argued that metaphor's role is more limited than CMT claims and that abstract reasoning has substantial literal-conceptual foundation
the methodology of identifying conceptual metaphors from linguistic expressions has been criticized as circular — researchers identify metaphors that fit their theoretical commitments and characterize linguistic expressions as evidence for those metaphors
the framework's mapping diagrams are often more elegant than empirical evidence supports — actual metaphorical reasoning is messier than CMT presentations suggest
cross-cultural variation in conceptual metaphors is substantial — some metaphors that CMT presents as universal show substantial cultural variation, while others that look culturally specific show more cross-cultural commonality
commercial popularization (Lakoff's political-framing work substantially influences Democratic political consulting) varies substantially in fidelity to academic framework
integration with formal linguistics and computational approaches has been incomplete
tendency in some applications to invoke conceptual metaphor decoratively without substantive analytical work
primary metaphor theory (Grady) and conceptual blending (Fauconnier-Turner) substantially extend CMT but also raise questions about which version of the framework is being defended
recent neuroimaging research has provided mixed support for embodied-metaphor claims.
