Natural History of the Senses- VISION

Like the book explained, often times when we look into the sky and see

emptiness, there are actually billions upon billions of things that are happening right

in front of our very eyes.  Due to restrictions in our brain  and vision function, we

are only able to consciously visualize a certain frequency of visual information.

Imagine a boy who is standing at the edge of a pond observing all of the animals and

organisms that live in the ecosystem.  To the boy, each organism and animal

observes the external world the exact same way he does.  However, this is not the

case.  The fish at the bottom of the pond, the tadpoles resting on top, and the birds

flying over the water all have different levels of visual processing in their brains.

Therefore, each one of these organisms views the world in a unique way that we are

unable to ever fully understand.  Our vision may be precise and accurate, but there

are many other animals that exist in the world that have exceptional vision

compared to humans.  For example, some birds are able to fly hundreds and

hundreds of feet above sea level while still being able to locate prey beneath the

water.  Clearly, some animals have increased their visual perception and awareness

due to biological adaptions.  Attached is an article explaining how different species

view the world.

The most primitive sense

By -

Smell the Flowers by Kirsten Star Smell, to me, is the most primitive sense. When most mammals are born, they immediately can recognize their mother’s smell and form an attachment to that smell. Mammals like puppies are almost entirely limited to only the sense of smell until they develop more of their other senses. The sense of smell also becomes the most primitive when considering humans and the phenomenon of perfume. For years, humans hunted certain animals for the purpose of obtaining the musk produced in the anal gland. This musk in small doses can act as an aphrodisiac when put into a perfume even though it has incredibly primitive origins. Though most of Western culture has an aversion to smells considered gross or undesirable, the wealthiest of women are still willing to pay heavy prices to spray a smell once obtained from the anal glands of other animals. The sense of smell is not something that humans can control and adjust but rather it is only changed by evolution over

Cannibalism and Symbolism

By -
Symbolism plays an important role in religious ceremonies because people cannot have the divine being where they want him all the time. So they start creating ways to be in touch with God. Such as in Christianity, eating bread is symbolized to be eating God-made flesh. There are similar rituals in Judaism where they eat the food of God. A big difference between taste and the other senses is that the object that is being sensed is internalized, whereas all the other senses use an external sensation. Taste cannot extend anywhere like the other senses can. This allows the humans to have no barrier between the divine (symbolized as food) and themselves. This is the closest they can get to God, but internalizing Him.  This thought of getting the closest they can to someone by ingesting and gaining power from it led my mind to wander to the thought of serial killers that also happen to be cannibals. I know that it might be a stretch, but there are some similarities. I als

Wrap-Up Post

Alright, let’s tie this up in a nice little bow. I genuinely did not know what to expect coming into this class. The extent of my knowledge of the senses comes from elementary school when we had to make it a little song to get the information through our tiny heads. Beyond that, everything seemed pretty cut and dry. We have five senses. We need to use all of them to survive. It’s as simple as that. I did not know how there was enough to talk about the senses to fill an entire college course, especially one specifically regarding the relationship between the senses and religion. But the fact that we were barely able to fit all the content in before the semester ended proves just how wrong I was. Let’s talk about why that is and what some of the things I learned were. First off, even the most basic assumption about the senses, that there are five of them, was questioned immediately. The sixth sense may not have been as clearly defined as the other senses, but there was certainly a lot to
