Realism

Naive Realism states that there are two things involved in interacting with an object, the perceiver and the object. 














Locke's scientific realism overcomes some of the problem's of naive realism by identifying primary and secondary qualities in objects. Thus, primary qualities like mass are real but secondary qualities like weight are affected by the perceiver.



















Representative realism states that there are three things, the perceiver, the perception and (possibly) the object.

By breaking naive realism's direct link between the object and the perceiver representative realism centres knowledge of the external world in the perceiver's mind. We can no longer be certain that the external world is as we perceive it.
