Originalism is a family of theories built on one claim: the meaning of each provision of the Constitution was fixed when it was adopted, and judges should apply that fixed meaning. It grew in the 1970s and 1980s through scholars such as Robert Bork and officials such as Attorney General Edwin Meese, and on the Supreme Court through Justices Antonin Scalia and Clarence Thomas, joined later by others. It leans on the textual and historical modalities.
Three versions
| Version | What fixes the meaning | Common criticism, and the reply |
|---|---|---|
| Original intent | What the framers meant to accomplish | Hundreds of drafters and ratifiers had no single intent. Most originalists moved away from this version for that reason. |
| Original public meaning (the main version today) | What a reasonable, informed reader understood the words to mean when ratified | Historical meaning can be hard to find. Advocates reply that courts weigh historical evidence all the time, and the method still narrows the choices. |
| Original expected application | The specific results people expected then | Few originalists hold it: the public meaning of a principle can reach facts the founders never imagined. |
Why it works
Key idea
Worked example: Public meaning, not private intent
- Private hopes of one drafter are not the meaning the public ratified.
- The originalist looks instead for how the word "commerce" was used in dictionaries, newspapers, legal writing and the ratification debates of 1787–1788.
- The letter might be weak evidence of usage, but it does not control.
Answer: No. Public-meaning originalism asks what the words meant to the ratifying public, not what one framer privately wanted.
Worked example: Originalism and new technology
- Separate the fixed meaning of a term from the facts it applies to.
- If "effects" publicly meant a person's personal property, a phone is personal property.
- The meaning stays fixed; its application reaches new things that fit it.
Answer: No. Public-meaning originalists hold that fixed principles apply to new facts. That is the difference from "expected application."
Common mistake
Critics answer that history is often unclear, that originalists disagree among themselves, and that the method gives authority to a generation that excluded many Americans from voting. Originalists reply that every method has hard cases, that unclear history calls for deference to legislatures, and that the amendments themselves, such as the Fourteenth, Fifteenth and Nineteenth, were the people's way of correcting the founding. The next lesson presents living constitutionalism as its advocates present it. You can read the founding debates yourself on the ratification debate page.
