Phenomenal Perspective

Consider the evidence of phenomenal perspective. Mathematically, perspective is defined as a transformation from a three-dimensional world, through a focal point, onto a two-dimensional projection. However phenomenal perspective does not appear as a two-dimensional projection, but as a distortion applied to a solid volumetric space. When standing on a long straight road, the sides of the road are perceived to meet at a point up ahead, and if you turn around, they converge also to a point back behind. And yet the sides of the road also appear to be straight and parallel throughout their entire length.

Nowhere in the objective world of external reality is there anything remotely resembling perspective as we observe it in phenomenal experience. The prominant violation of Euclidean geometry in phenomenal perspective is perhaps the clearest evidence for the world of experience as an internal rather than an external entity, for the curvature of perceived space is clearly not a property of the world itself, only of our perceptual representation of it.
