 Statements expressing our beliefs about reality are translatable into, and thus entail and are entailed by, an indefinitely large set of counterfactual statements about what experiences we would have or would be likely to have, were we to be presented with certain sensory cues and were we to carry out further tests (Lewis 1929, 142; 1946, 180, 208). Objectively, what we actually experience may depend on the physical circumstances of perception, e.g. lighting conditions, and the bodily actions we perform, e.g. moving our eyes, as well, of course, as the character of objects in our environment. However, what matters ultimately for the meaning and confirmation of statements about objective reality, as Lewis makes clear in AKV, are only the “felt experience” of action and the directly presentable sense experiences contained in sensory cues and forming the experiential circumstances of action (Lewis 1946, 178–9, 245–6), as well, of course, as the directly presentable sense experiences they lead us to expect. The idea of a reality neither confirmable nor disconfirmable in principle by experience was thus for Lewis without meaning. What distinguished his view, he thought, from the superficially similar verification principle of meaning of the logical positivists was his emphasis on the mediating role of agency (Lewis 1941a, in Lewis 1970, 94).
