|Internalism||Frank I 688
BurgeVsInternalism/Individualism: false development of the Cartesian argument: confusion of truth conditions with the conditions of individuation.
1) Descartes asks whether our thoughts are true in counterfactual situations: they are not.
Important Point: this assumes that the thoughts are identical with the corresponding ones from the original situation!
I.e. the conditions of individuation remain constant, the truth conditions change.
Twin Earth/BurgeVs: in fact it is the other way round: the conditions of individuation change.
We know what thoughts we have in the current situation and can imagine that they are wrong. We would also know in a counterfactual situation which thoughts we would have in this situation.
But in the current situation, we do not know anything about thoughts that we would have in counterfactual situations.
Therefore, Cartesianism cannot support internalism.
