If that"s how mental operations work, then we need representations. If is a for(cid:373)ula, the(cid:374) ~ is a for(cid:373)ula: the rule is recursive; can have infinitely many formulas. If raining causes you to be wet, and it"s raining, can conclude that i am wet: gi(cid:448)e(cid:374) the for(cid:373)ulas --> a(cid:374)d ~ , (cid:272)o(cid:374)(cid:272)lude ~ (cid:894)modus tolle(cid:374)s(cid:895) If raining causes you to be wet, and i"m not wet, it means it"s not raining. Why a language of thought: explains, productivity: the ability to represent infinitely many thoughts (cf. Chomsky on sentences: systematicity: the ability to freely recombine thoughts.
