Originalism comprises the family of theories of constitutional interpretation that give primacy to some aspect of the Constitution at the time it was ratified. This original aspect is variously taken to be the intentions of the framers or ratifiers of the Constitution, the meaning of the text, the way in which the text would have been understood by the ratifiers of the Constitution, or well-established practices at the time.[14] See entry on Constitutionalism. Originalism thus includes both intentionalist and non-intentionalist theories of interpretation. What the various forms of originalism have in common is their taking the correct interpretation of the Constitution to be fixed by a particular feature of the Constitution at the time of ratification. It promotes clarity to frame this core idea in terms of the Constitution’s contribution to the content of the law (though originalists do not always do so): that contribution is fixed by the relevant aspect of the Constitution at the time of ratification and does not change thereafter.
