The language of thought: still a salient issue
Part of the Philosophy of AI: Optimistic and Pessimistic View lecture series, on 25.05.2022 Jakub Szymanik gave a lecture at c:o/re on Reverse–engineering the language of thought, problematising thought and computation by exploring the cognitive scientific notion of language of thought (“mentalese”). This concept, positing that humans think through logical predicates combined through logical operators, originates in Jerry A. Fodor’s celebrated book (1975), explicitly titled Language of thought. In effort to reverse-engineer the language of thought, Jakub Szymanik considered some recent computation theories, such as inspired from Jerome Feldman and neural networks in a fresh manner.
Jakub Szymanik explained that the notion of language of thought is not easy to avoid: it is often the engine underpinning theories of cognitive models, via notions of complexity and simplicity. The investigation leads to a broad variety of theoretical implications and empirical insights, among which there can be many contradictions. However, apparently divergent approaches at play here, such as, for example, symbolism and enactivism are not necessarily and entirely irreconcilable. The way forward is through pragmatically pursuing the epistemological unification of such theories, as guided by empirical insight.
