naive realism

For other meanings of the term realism, see realism (disambiguation). Naïve realism is a common sense theory of perception. Most people, until they start reflecting philosophically, are naïve realists. This theory is also known as "direct realism" or "common sense realism".Naïve realism claims that the world is pretty much as common sense would have it. All objects are composed of matter, they occupy space, and have properties such as size, shape, texture, smell, taste and colour. These properties are usually perceived correctly. So, when we look at and touch things we see and feel those things directly, and so perceive them as they really are. Objects continue to obey the laws of physics and retain all their properties whether or not there is anyone present to observe them doing so.
