Can we really state that we can know something?
Know seems to be the most popular verb that can be said in a day. People say that word anywhere, anytime. And when they say that, almost everyone think that they are true. People also use knowledge to compete against others. In modern society, the person who has a wider knowledge is always attached much important than the person with a normal knowledge. But can we really be sure that we know something truly?
First of all, we have to look at the way how we can access to the resources of knowledge. There are four methods for us to do that. They are sense perception, language, emotion and reasoning. The next step is to find out about each of them
Let say first about the sense perception first. Most people say that there are 5 senses perception: hearing, taste, touch, smell and sight. Somebody says that there is also the sixth sense perception, the sense of prediction, but we just usually use the 5 senses above. According to some famous psychologists, there are 3 parts for us to acquire knowledge by sense perception. Firstly, our sense receptors are stimulated by sensory information. Then the brain translates that sensory information into sensation such as sound, taste, temperature, pressure, smell, or sight. Finally, higher centers in the brain either ignore or recognize the sensation and their meaning, based on neuronal networks of past association and expectation. So the sense perceptions sound to be reliable, doesn’t it? However, it is not totally trustworthily as it was thought to be. It is because of a fact that the whole body does not always work properly. Sometime there will have some problem with our brains, which lead to an incorrectness in the knowledge we gain. Another reason for this phenomenon is the illustration. There is no doubt that our eyes are easily tricked.
