Naturalists hold that attention to, respect for, and coherence with critical findings in the empirical sciences abet philosophical proposals. Moreover, the border between high-level scientific theorizing and the speculations of some naturalistically inclined philosophers in some fields has become increasingly porous. In such a milieu it should come as no surprise that naturalists search the newest experimental studies in relevant empirical sciences for results that seem to bear on philosophers’ various pronouncements about knowledge, language, and mind. Occasionally, though, findings of interest arise not from current scientific studies but rather from earlier scientific work that was overlooked in the original philosophical discussion. That is what we will be up to here, specifically examining long-standing findings about the Müller-Lyer illusion that philosophers have neglected.
