 CCTM+FSC says that the mind is a formal syntactic computing system: mental activity consists in computation over symbols with formal syntactic properties; computational transitions are sensitive to the symbols’ formal syntactic properties but not their semantic properties. The key term “sensitive” is rather imprecise, allowing some latitude as to the precise import of CCTM+FSC. Intuitively, the picture is that a mental symbol’s formal syntax rather than its semantics determines how mental computation manipulates it. The mind is a “syntactic engine”.
