Naive realism, also known as direct realism or common sense realism, is a philosophy of mind rooted in a theory of perception that claims that the senses provide us with direct awareness of the external world. In contrast, some forms of idealism assert that no world exists apart from mind-dependent ideas and some forms of skepticism say we cannot trust our senses.
The realist view is that we perceive objects as they really are. They are composed of matter, occupy space and have properties, such as size, shape, texture, smell, taste and colour, that are usually perceived correctly. Objects obey the laws of physics and retain all their properties whether or not there is anyone to observe them.
Naive realism is known as direct as against indirect or representative realism when its arguments are developed to counter the latter position, also known as epistemological dualism; that our conscious experience is not of the real world but of an internal representation of the world.
The naive realist theory may be characterized as the acceptance of the following five beliefs:
- There exists a world of material objects.
- Some statements about these objects can be known to be true through sense-experience.
- These objects exist not only when they are being perceived but also when they are not perceived. The objects of perception are largely perception-independent.
- These objects are also able to retain properties of the types we perceive them as having, even when they are not being perceived. Their properties are perception-independent.
- By means of our senses, we perceive the world directly, and pretty much as it is. In the main, our claims to have knowledge of it are justified.”
Make no mistake: these are a set of beliefs. And these beliefs, in some ways, operate in opposition to current neuroscientific findings. For example, current neuroscience claims that our perceptions of the world are neurological reconstructions; that is, our perceptions are merely compositions put together by our brains, based on a set of limited sensory inputs. And when we take into account the notion that we what we perceive through the five senses makes up a very small part of the known electromagnetic spectrum, it seems rather foolish to assume that what we perceive with the senses is the bare, naked truth of reality.
It is precisely because of the rigidity of these beliefs within naïve realism that naive realists are caused to assume that consciousness is the hard problem. In the following interview, Deepak Chopra talks of science's approach to consciousness, and suggests that it is matter, not consciousness, that is the hard problem.
