The concept of primary and secondary qualities is a little difficult to understand still if we look to other sources for the proofing of the concept we might find a better explanation to the idea. Locke not only used the method of variability in his studies to differentiate between the two but also employed the method of measurability. According to him, if the object is measurable then it definitely is a primary quality because only the primary qualities can be measured like the size and mass. But with the advancement of science we now know that even the colours can be measured through frequency and wavelengths measurement which are considered secondary qualities by Locke. Hence, the measurement idea is not true.Because of the failure of the concepts of Locke in discriminating between the primary and secondary qualities it is best to look elsewhere for evidences that support the primary and secondary quality theory. Once we broaden our research and look away from Locke, we find that many other philosophers also have worked on the theory presented by Locke. Aristotle was the one who first presented the idea that there is a difference in between the objects that are concerned with a single sensory organ and those that have an effect on multiple sensory organs especially the eyes and the hands. This proves that Locke’s theory was not an original one but was in fact a derived one.
