The Nature of Perception Do we see the world the way it “really” is? • Eidolon Theory (Democratus) • Ray Gun Theory (Euclid) • Naïve Realism • Why the Theory of Naïve Realism is Flawed
Eidolon Theory: Democratus
Ray-Gun Theory: Euclid
The Theory of Naïve Realism We see the world the way we see it because that’s the way it “really” is
Why the Theory of Naïve Realism is Flawed 1. Different individuals see the world differently • Different species see the world differently
Electromagnetic Spectrum Light at different wavelengths is experienced as different colours

Perception depends on the interaction between stimuli from the world and our sensory systems
