John Locke was an influential 17th century English philosopher known for his works on epistemology and political philosophy. His most influential political work was Two Treatises of Government, in which he rejects the idea of a king's divine right to rule and argues that civil government is based on the natural rights of the people. Locke believed people are naturally free and equal in a state of nature prior to government, and that government should protect people's property rights and be formed by consent of the governed. He also wrote An Essay Concerning Human Understanding, where he explored the distinction between primary and secondary qualities and the role of experience and language in human understanding.

7. These sensations created by Secondary Qualities produce an idea. This is done by impulse into our minds through our senses. The Primary Qualities are the crucial and inseparable qualities of a body. These qualities are found in the body until it becomes insensible and include its solidity, extension, figure and mobility. Powers that produce sensations such as colour in our mind are what Locke calls the Secondary Qualities. Simple Ideas and the role of Primary and Secondary Qualities “ An Essay Concerning Human Understanding”, first published in 1690. The argument;

8. How does this relate to the real world? Example ; the rose, by impulse of its solidity, extension, figure and mobility affect our senses and cause ideas . This produces sensations which we receive from the colour and smell of the rose. This causes the idea of pink and a sweet scent of the flower to be produced in our minds.

9. The power to produce ideas by our senses are looked upon as real qualities in the things affecting us. But Locke argues that this belief is wrong by explaining that the effects of the sun on wax, which we see produces softness in the wax, not as a quality of the sun, but an effect produced by powers in it. They are all equally powers in the sun (body), which depend on its Primary Qualities. Example ; We believe that the idea of light which we receive by our eyes from the sun to be a quality existing in the sun (body). Are we mistaken in our beliefs?
