 It has been argued that as long as we assume FP is any kind of ToM then it won’t remain in the theoretical running unless it allows for revision and is prepared to incorporate the latest findings of mature scientific theorizing about minds (Murphy 2006; Gerrans 2014). Assuming FP is not open to such significant, open-ended revision, Churchland (1989) famously characterizes it as a stagnant or degenerating research program.
