TOK NOTES TUESDAY 13 NOVEMBER 2018 Perception Your mind has to interpret what your senses see Perception = senses data + interpretation The same applies to other senses also. Thermoception Problems: » It you put your left hand in a bowl of ice, and your right hand in a bowl of hot water, and then put both hands into the same bowl of tepid water, then it will feel hot to one hand and cold to the other. Visual Agnosia: » Visual agnosia is the inability of the brain to recognise patterns in visual data. This means that the person finds it difficult to recognise what they are looking at. The person has lost their meanings of interpreting. » Those with visual agnosia may find it difficult or impossible to recognise faces, or tell the difference between a house and a bungalow. One man with visual agnosia “mistook his wife hat” and confused bits of fluff with expensive jewellery. He couldn’t even recognise his own house. Paradigm: » A paradigm is a way of understanding and interpreting things. People have to interpret what they see by putting patterns on it, but this will be connected to their entire world view. » Each of us have our personal paradigm in which we connect what we see to various ideas, words and emotions. Knower’s Perspective: » This is the idea that people from different backgrounds will often have a different way of seeing and interpreting the world. Seeing is believing… isn’t it? » A key problem with using the senses as a way of knowing is that people can misinterpret what they are seeing. Rene Descartes: Descartes was a French philosopher and he wanted to work out for certain what was true and could be known and what might be false.
