A Philosophical Critique of Theory of Mind (ToM) and the Double Empathy Problem as Its Grounds
Theory of Mind (ToM) refers to a hypothesized faculty presumed to enable a person to infer others' beliefs, intentions, and so on. In other words, someone whose empathic capacity is highly developed is regarded as having a highly developed ToM faculty. As a hypothesized faculty, ToM is posited either as a precondition for empathy, or empathic capacity is evaluated on the basis of ToM by appealing to the fact that communication breaks down when ToM is impaired.
However, this notion of ToM ought to be criticized from a philosophical standpoint. Myson of Chenae, one of the Seven Sages of ancient Greece, declared that one should not seek fact from speech (argument, logos), but should seek speech from fact—because facts do not exist in order to conform to speech; rather, speech exists in order to conform to fact. That is, argument ought to be derived from fact. Yet ToM first posits a hypothetical faculty called "Theory of Mind" and then schematically fits empathic capacity—which belongs to the domain of fact—onto that posited faculty. In this sense, ToM commits the error of judging empathic capacity on the basis of an antecedently assumed argument. Indeed, this error is borne out by the empathic capacity observed between autistic people in mutual interaction—people for whom this hypothesized faculty of ToM is said to be absent.
The so-called Double Empathy Problem is the theory that communication between two autistic individuals is, by comparison, not inferior to communication between two non-autistic individuals. Insofar as autistic people's empathic capacity is not premised on ToM, this provides grounds for dispensing with the hypothesized faculty that ToM presupposes. If the hypothesized faculty of ToM were truly absent in autistic individuals, then communication and empathy should fail even between two autistic people, since both parties would be equally "deficient." Yet the fact that communication between them proceeds smoothly indicates that it is unwarranted to posit ToM as a precondition for empathy.
In conclusion, the claim that ToM functions as a precondition for empathy is unpersuasive, since it amounts to deriving the fact of empathy from the argument (speech) of "Theory of Mind"—a schema in which speech precedes fact rather than the reverse. This conclusion is further supported by the Double Empathy Problem, which shows that mutual engagement between autistic individuals proceeds smoothly even though ToM, as a precondition, is not operative between them.
