He suggested that bodies do not exist, and if they exist, only one body existed, not separated by anything nor vacuum. In Descartes study on the nature of bodies, he concluded that the real nature of bodies can only be determined via intellect and not by sense perception neither by imagination. Contrary to his initial perception that he himself was a thinking object without a body, Descartes observed that physical objects existed and can be determined via rational intuition.Out of the five senses, none can detect the existence of bodies. Descartes proved this point by using the wax example. He intuited that wax is a physical substance. In its first appearance, wax has a scent; it has a visible shape, can be touched and even produces some sound when tapped. With the human imagination, then this object, noted by the various senses is wax. Upon heating the wax, it melts, the scent disappears, it becomes shapeless and can even be mounted into any shape, and it cannot be touch in sanity. But is it not wax? Note that everything that was used to identify the wax has changed, but no one disagrees that the new feature formed is not wax. Therefore, Descartes concluded that ‘the wax’ is an extended stuff and not the physically visible object. The mind determines what wax, or any other object, is, without consulting any of the five senses or even imagination.According to John Locke, innate principles do not exist, but ideas are triggered by past experience. Factually, children are born with a blank mind, and as they grow they can only remember what they experienced. Locke claimed that, existence of innate ideas should be backed up by universally agreed principles. The latte does not exist, as matter of fact the basic idea that ‘what is cannot be what it is not’ is objected by idiots. Secondly, Locke agreed with the nativist that, the mind has native capacity to entertain certain ideas. However, Locke claimed that this innate capacity does not constitute an innate principle and deemed the nativists doctrine baseless. To Locke, innate capacity can only be triggered by experience or a situation, just as the nativist claimed and thus different situations will make individuals reason differently. In a nutshell, Locke claimed that, innate principles are extinct, there exists innate capacity but ideas can only be grasped from experience at the time when the mind knows what do with the ideas
