Realism

Realism splits into two categories; non-reductive realism and reductive realism. Non-reductive realism states that there is no difference between a primary and secondary quality. A primary quality is a known physical property like shape and weight and a secondary quality is a quality which is perceived, like color and smell. Non-reductive realism takes the point of view that these qualities are one in the same. Therefore, this theory sets forth the idea that an object appears to be a certain color because it truly is that certain color. Just like a blue ball is round, the ball is also blue. On the other hand, reductive realism says that an object is colored because a color is said to be a set of complex physical properties which reflect wavelengths in order for that it becomes that color. Reductive realism can be further split into two sections; physicalism and dispositionalism. Physicalism presents the idea that an object will appear a certain color because it possesses the set of properties attributed to that color. However, physicalism has been strongly scrutinized due to the fact that two things with completely different physical properties can create the same color. Dispositionalism explains that objects have a certain color because they have a disposition or inherent quality to appear that color.
