uniformitarian
C2Academic, Scientific, Technical
Definition
Meaning
An adjective describing the geological theory that existing processes, acting in the same manner as at present, are sufficient to explain all past geological change.
More broadly, it denotes a principle of assuming that the same natural laws and processes that operate in the present have always operated in the past, opposing catastrophic explanations of history.
Linguistics

FAQ
Frequently Asked Questions
The term was coined by the British polymath William Whewell in 1832, in opposition to 'catastrophist'.
Modern geology incorporates a revised form, sometimes called 'actualism', which accepts the uniformitarian method but also acknowledges that the rates and intensities of geological processes have varied and that rare catastrophic events (like asteroid impacts) occur.
Uniformitarianism emphasises slow, incremental change over vast time scales, while catastrophism emphasises sudden, violent, and often global events as the primary drivers of geological change.
Yes, by analogy in fields like linguistics (e.g., assuming language change is always gradual) or history, though this is a specialised metaphorical extension.
