Sensory perception is one of our ways of knowing and is fundamental to our understanding of the world around us. The quote above from William Blake highlights how our perception can easily be altered and unclear to us. Blake's commentary was popular in his day and ours, giving its name to one of the world's most celebrated rock bands, the Doors. This prescribed title implies what we consider to be the “truth” and our five windows on the world, sight, smell, taste, touch and hearing, constantly inform us about our environment and our accurate perceptions of it. One of the knowledge issues with this suggestion is whether or not we can assume that everyone has the same concept of “truth.” For the purposes of this article we will focus on whether truth is “reality” and what actually exists in our external worlds. It has been observed and measured by natural sciences that our end organs (ears, nose, tongue, eyes and neurons) -receptors) are at best imprecise connections to the outside world. This can be demonstrated by our limited efficiency in using sight alone. It has been recorded that of the total light spectrum, from microwaves to macrowaves, humans can detect only a narrow band of waves in the central region known as the color spectrum. This small section of the total light waves makes up only 10% of the larger expanse of waves. Assuming that humans only see this limited amount of light reflected from objects and must make inferences about the external world, it can logically be said that our input of information about that world is truly incomplete. This can be further illustrated by our inability to detect the radio waves that continually pass through our bodies and homes. A radio receptor found in the simplest radio devices, has... middle of paper... yet the truth is that in the end it was all a lie simply to cheat us out of our money. This form of subterfuge is ancient, dating back to the dawn of time, when people's greed and creativity combined to mislead others for an evil purpose. Today the commercial and consumer mentality is bombarded by advertisements for products that claim to have certain properties. We must use good judgment to find the truth in all these created perceptions. In conclusion, our sensory perception is our only input to external worlds in which we must attempt to successfully thrive. Understanding that our five senses are critical to this, we must recognize that misconceptions and falsehoods are often made. In a world of Photoshop and Reality TV that is essentially not real, we owe it to ourselves to seek the “truth” as best we can.Bibliography
