Twin earth: is an expression from a thought experiment by H. Putnam (H. Putnam, The meaning of ‘meaning’, In Philosophical Papers, Vol. 2 Mind, Language and Reality, Cambridge, 1985). It is assumed that there is a second earth, which resembles our own in every detail, except for the composition of the substance water. However, the twin earth-water has phenomenologically the same properties as our water and is also called water there. The example should show that we cannot determine the reference of expressions independently of the environment. See also reference, externalism, internalism, anti-individualism.
