|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.

|Twin Earth/TE: a particular word usage may be right in one situation and wrong in a different one, even if one cannot distinguish between the situations.
Twin Earth: the inhabitants do not need to be able to specify that they have different terms. They are not omniscient.
Visitors might use the terms inappropriately, the circumstances of the right non-inferential use of the German word for "water" requires that it is used as a response to H2O.
Order/Twin Earth/Brandom: it does not help to speak in concepts of what individuals can distinguish, because what they can react to depends on what reactions are considered to be different and the same problem occurs with regard to the vocabulary used - Problem: specifying vocabulary that fulfils two conditions: 1) The twins must be indistinguishable in different environments because of their description in that vocabulary (physical language is not enough for that) - 2) The sub-determination of the semantic properties of their states in this limited vocabulary must show something interesting._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
