Locke, when presenting his theory of representative realism, focused on the differences that existed between the primary and secondary qualities. His work on this subject is basically a rectification of the naive mindset of the people. It is because of this naive nature that the people tend to confuse the two qualities together. Locke while explaining the human psyche said that the images of the items present in the real world are formed in our minds as ideas and are only symbolic representations of what is actually present. He is of the opinion that all the items and things present in the external world are analysed by our mind on the basis of having two types of qualities either primary or secondary.The primary qualities are the ones that have a direct relation to the object’s being. This means that if the object’s picture that is in our mind is not having the primary quality than the picture would remain incomplete and the true sense of the object would not be formed in the mind. Because of this integral relationship in between the primary quality and the object our mind visualizes the primary quality as the object itself. The example of primary quality would be mass and not weight. This is because mass is not dependent while weight depends on gravity.
