|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.

|Dennett I 268
Twin Earth/Monod/Dennett: Monod posed and solved the problem of Putnam's twin earth: meaning is not in the head, it is also not quite in the DNA.
Dennett: this also applies to the poetry (> hermeneutic circle).
In the opinion of some authors, "gene centrality" is thus disproved.
Dennett: that was an over-simplification anyway.
Niche: every functional structure implicitly carries information about the environment in itself._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
