 In addition to making these various arguments for sense data, Robinson (1994: ch. 7) also raises objections against what he takes to be the primary opponents: intentionalism and the adverbial theory. He further suggests that, if his arguments for sense data are sound, this finding would support a phenomenalistic idealism over physical realism (1994: chs. 8–9). (On idealism, see Guyer &amp; Horstmann 2015 [2021]; on realism, Miller 2002 [2019].)
