 Jerry Fodor (1974) extended Putnam’s initial argument by arguing that reductionism imposes too strong a constraint on acceptable theories in special sciences like psychology and economics. According to Fodor, reductionism is the conjunction of “token physicalism” with the claim that there are natural kind predicates in an ideally completed physics corresponding to each natural kind term in any ideally completed special science. He characterizes “token physicalism” as the claim that all events that science talks about are physical events. Token physicalism is a logically weaker thesis than reductionism or type-type physicalism. To illustrate why, consider the following string of numerals:
