Abstract:
This research is a study of how Barkley rejects the distinction of Primary and
Secondary qualities put forwarded by John Locke, regarding Human knowledge in his book “A
Treatise concerning the principle of human knowledge”. Empiricist John Lock said that the
Human knowledge is obtained through two ways which are perception and reflection. And what
the mind sees immediately from this internal impressions he called “ideas”. Locke differentiated
them into simple ideas and complex ideas. External matters have inherent powers to create
these ideas within us. Locke called these powers “Qualities”. These qualities were differentiated
into primary and secondary qualities. Locke had revealed in his book, “An Essay concerning
Human understanding” that Primary qualities are concerned with materials and secondary
qualities are not concerned materials, it is different human to human. Although Locke
differentiated between these two qualities, he could not clarify the relationship between them.
Hence, so as to rectify this short comings, Berkley rejected Lock’s quality differentiation in his
book and try to reach a solution by explaining that the primary and secondary qualities co-exist
indivisibly, and all these remain relative to our mind and nothing else. For explain this study
Analytical method and critical method are also utilized and data for the study were obtained from
literature, magazines, and internet.
