Document Summary
Biased view: world is how we perceive it to be. Chess pieces, top is black background, looks like white pieces. Used to chess pieces being in different colours. We think this is exactly how the world is. One person in black left the game. Person wears goggles so they have visual experience with infrared experience. You can see where person was and where they were a while ago, based on heat. No such thing as colour in the world. Colour is something that the brain is interpreted. Two frogs, one dull brown frog, avoid predators. Strawberries, ripe (red) and unripe (green), forging for food in environment. Advantage over another organism that doesn"t have that ability. Colour perception is an advantage in terms of hunting for food. Humans are sensitive to blood flow, leave to different colouration. Lead to fertility, explain health based on colour. Some might have 2 types of cones.
