Human science to objects from point of view of John Locke and Mohaghghegh e Lahiji

The problem of knowledge and level of human knowledge of objects is one of the important issues of the history of thought and philosophy. Hakim Mulla'abdolrazzagh Lahiji (1072 AH) and John Locke (1632-1704) are among the philosophers who have investigated the subject of knowledge and level of human knowledge. Mohaghghegh e Lahiji believes in a theory that in Islamic philosophy refers to it as a "Phantasm of Representative" (Shabah e Mohaki).In his book, Shavaregh Al-Elham, he states that we when knowledge to objects do not achieve in the their essence and reality, but achieve the phantasm that represent from the outer object. John Locke, also, in his precious book, An Essay Concerning Human Understanding , recognizes two different meanings of essence and distinguishes between the real essence and the nominal essence of objects, and knows our knowledge of things about their nominal essence. The similarity between Lahiji and Locke is that both know power of human are more limited than they are to achieve the reality and the essence of objects, but they differ in the quiddity of knowledge and perception.
