Document Summary

Realism: a philosophical position arguing that there is a real world to sense. Positivists: a philosophical position arguing that all we really have to go on is the evidence of the senses, so the world might be nothing more than an elaborate hallucination. Geometry becomes non-euclidean when the 3d world is projected onto the curved, 2d surface of the retina. Parallel lines in the world do not remain parallel in the retinal image. Angles of triangles won"t always add up to 180. Our visual experience is a reconstruction of the world based on two non-euclidean inputs: the two distinct retinal images. They differ because the retinas are in slightly different places in your head. Monocular depth cues: depth cue that is available even when world is viewed with one eye. Binocular depth cue: a depth cue that relies on information from both eyes.
