Abstract Yli-Vakkuri (2018) argues that content externalism can be established without thought experiments, as the deductive consequence of a pair of uncontroversial principles about beliefs, contents and truth. I argue that the most dialectically plausible motivation for the first principle, that truth is a broad property or beliefs, undermines the second principle, that the truth-value of a belief goes hand-in-hand with that of its content, and that other motivations are likely to depend on externalist thought experiments the argument was meant to avoid. As it stands, the argument for externalism therefore fails.

The Individual

Externalism with respect to content is the thesis that the contents of an individual's mental states are fixed, not just by the intrinsic physical characteristics of the individual, but also in part by the external circumstances of the individual. This idea can be illustrated by means of thought experiments involving pairs of ‘twins’ who are identical with respect to their intrinsic features yet who differ mentally because of differences in their environments. The thoughts of a thirsty earthling may turn to water. Suppose that an earthling has a molecule-for-molecule twin on a very distant planet, a planet identical to Earth except that wherever Earth has H2O, Twin Earth has XYZ, which is superficially indistinguishable from water. When the twin is thirsty, her thoughts will turn instead to twater, as we may call it. Externalism about content is a metaphysical thesis, but it has epistemological implications. Many have argued that externalism is incompatible with a suitably rigorous thesis about the authoritative, introspective self-knowledge we seem to have with respect to our own thought contents.

Field Of Inquiry

The paper considers the analogy of theoretical modeling and thought experiment in economics. The authors provide historical and epistemological analysis of thought experiments and their relations to the material experiments in natural science. They conclude that thought experiments as instruments are used both in physics and in economics, but in radically different ways. In the natural science, a thought experiment is tightly connected to the material experimentation, while in economics it is used in isolation. Material experiments serve as a means to demonstrate the reality, while thought experiments cannot be a full-fledged instrument of studying the reality. Rather, they constitute the instrument of structuring the field of inquiry.
