Document Summary
Realism: philosophical position arguing that there is a real world to sense. Positivists: philosophical position arguing that all we really have to go tn is the evidence of the sense, so the world might be nothing more than an elaborate hallucination. Euclidean: referring to the geometry of the world. Retinal area occupied by an object gets smaller as objects moves farther away from the eyeball. Our visual exp is a reconstruction of the world based on 2 non-euclidean inputs: the 2 distinct retinal images: retinal images differ because the retinas are in slightly different palces in your head. Having 2 eyes confers the same evolutionary advantage as having 2 lungs or 2 kidneys: another advantage is that it enables u to see + of the world. Our visual field is limited to about 190 degrees from left to right, restricted vertically about 140 degrees, 60 up and 80 down to your cheeks.
