 A subtler form of skepticism about spatial audition aims just to block the requirements on objectivity. Strawson (1959) famously argues in Chapter 2 of Individuals that because auditory experience is not intrinsically spatial—spatial concepts have no intrinsic auditory significance—a purely auditory experience would be non-spatial. Thus, it would not satisfy the requirements on non-solipsistic consciousness. Others have endorsed versions of Strawson’s claim. “[T]he truth of a proposition to the effect that there is a sound at such-and-such a position must consist in this: if someone was to go to that position, he would have certain auditory experiences,” states Evans (1980, 274).
