符号计算主义与意向实在论

符号计算主义的意向实在论论证的要点,是表明具有语义性质的命题态度的因果效力。然而,在这里,命题态度的因果效力是通过命题态度的句法性质而得到论证的。这就给符号计算主义的意向实在论论证带来了问题:命题态度的语义性质如何能够对认知系统的行为具有因果相关性?语义性质的因果效力问题是意向实在论论证的关键所在。因此,符号计算主义对意向实在论的论证是不成功的。

Symbol Computationalism and Intentional Realism

The intentional realist argument made by symbol computationalists is to show that propositional attitudes with semantic properties are causally efficacious. However, the causal efficacy of propositional attitudes here is based on the syntactic properties of the attitudes. This raises problems for the intentional realist argument: How is the semantic property of the propositional attitudes causally relevant to the behaviours of the cognitive system? The key to the intentional realist argument is to show the causal efficacy of semantic properties. Therefore, symbol computationalist argument for intentional realism is unsuccessful.
