I have noticed a lot of material on the Internet the last several years on the topic of mental reality, possibly inspired by the movie, The Matrix. It seems that many people are fascinated by the idea that human mental reality may be different from real reality. I think this is a mistake.
The idea originates from early modern philosophy. The basic reasoning holds that real reality is made known to our minds through our senses. Thus, what we “know” about reality is only what our senses present to us. A lot of science seems to confirm this view, but there is reason to be skeptical.
Specifically, if you assume that the purpose of the mind is to somehow capture or record real reality, then it might bother you to learn that mental reality is a very bad recording.
But you could assume, instead, that the purpose of the mind is to react to real reality and that the behaviors of the mind are the behaviors of reaction, not of representation. In that case it would be a mistake to confuse the mind’s reactive behavior with its direct and true experience of real reality.
Put another way, our senses may be, indeed, the conduits for real reality that we imagine them to be, not the filters the early modern philosophers imagined.
