 The first ramification concerns seeing objects. According to many views, we see ordinary extended objects by seeing their surfaces, rather than seeing them directly (see Moore 1918 or Broad 1952, and Clarke 1965 or Campbell 2004 for dispute). As far as seeing objects goes, their facing surfaces play the same role as sense-data did on many versions of the sense-datum theory—intermediaries not identical with objects that still permit us to see objects by seeing them.

Our experiences might fail to give us access to whether we live in a world of ever shifting facades or instead a world of three-dimensional objects as they are ordinarily conceived. Descartes arguably states this problem when he writes:
