Single Idea 4099

[catalogued under 18. Thought / C. Content / 5. Twin Earth]

Full Idea

Putnam claims that the Twins have different thoughts even though their heads are the same, so their thoughts (about 'water' or 'XYZ') cannot be in their heads.


The Twins live in identical worlds, except for the chemistry of so-called 'water'

Gist of Idea

If Twins talking about 'water' and 'XYZ' have different thoughts but identical heads, then thoughts aren't in the head

A Reaction

Is Putnam guilty of a simple confusion of de re and de dicto reference?
