| 14922 | The Ramsey sentence describes theoretical entities; it skips reference, but doesn't eliminate it [Ladyman/Ross] |
| Full Idea: It is a mistake to think that the Ramsey sentence allows us to eliminate theoretical entities, for it still states that they exist. It is just that they are referred to not directly, by means of theoretical terms, but by description. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 2.4.1) |
| 14921 | The Ramsey-sentence approach preserves observations, but eliminates unobservables [Ladyman/Ross] |
| Full Idea: If one replaces the assertions of a first-order theory with its Ramsey sentence (giving a quantified predicate variable for a theoretical term), the observational consequences are carried over, but direct reference to unobservables is eliminated. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 2.4.1) | |
| A reaction: Thus this rewriting of theories is popular with empiricists, and this draws attention to the way you can change the ontological commitments simply by paraphrase. ...However, see Idea 14922. |
