'We see and understand things not as they are but as we are'
Christopher Columbus, in the 1440’s on his voyage to America, saw three mermaids and described them as insight of females who rose from the sea. Did Christopher Columbus Imagine the mermaids because he was interested in fantasies or did he actual see it? On one hand I do believe that we understand and see things not as they are but as we are, on the other hand disagree with this statement. The way we view things reflects on our personality and each of our personality is different and some people also have similar personality. “We do not see things the way they are but as we are” is said to be a Jewish proverb. The proverb talks about how we are engaged with sense perception. It implicates how each individual has 6 senses and the 6th sense is within oneself. We understand things as we are but not as they are could also relate to emotion from knower’s perspective when I get afraid then I see images pass in from of me, so do I see the images in my brain or is it in from of me? I am relating this statement to two ways of knowing, Sense perception and emotion.
Sense perception, the first way of knowing, is our physical response of our senses to stimuli. There are only 5 sense and they include sight, taste, touch, hearing and smell. The sense receptors first pick up the signals after being simulated by the brain the information is transformed into sight, taste, touch, hearing and smell. These senses have become a part of our lives without them we would be the abnormal one in this world. Senses surround us everyday and every minute of our lives.
Emotion is our second way of knowing is human’s direct experience of the world. Emotions are the most powerful things in this wo...

...s changed the way the world looks and things. When a Hotel wants to stay in business then they Photoshop the pictures of the room and make it look nice but the truth is that the rooms are really bad. The hotel wants people to see the room as beautiful so they stay at the hotel. Photoshop foreshadows fake things so never believe what you see.
We see and understand things as we are but not as they are. In some cases this statement is true and in other cases this statement is false. We don’t always see and understand things the way we want to but we also see things the way they seem not exactly the way we want to. The world is an illusion by itself, this proves to us that we don’t always have too see things the way they are but we could also see them as we are. It’s the choice of the human mind to understand things and each mind is different; that is the nature of man.
Without perception, in our illusions and hallucinations, we lose “our sense of beings,” (Capra). Lost in “isolation,” (Capra) perhaps lost within our own illusion, our abstractions, we lose the ability to judge, to dichotomize, reality from illusions, right from wrong.
In the Allegory of the cave, Plato stated "what he had seen before was a cheat and an illusion, but that now, being near to reality and turned toward more real things, he saw more truley." It appeals to me because he's basically inferring what if what we are seeing or what we believe are just our figments of our imagination. A lie that we dwell on, because we are blinded from the truth. Plato statement is something we can all relate. For instance children from our younger years our parents disguise parts of reality to prevent them to live a life of fear. Fear of evil and fear from being hurt. But we as grow older we learn, that there is hate and evil in the world. We learn that not every corner has a rainbow glistening in the sky. And for that
...what one wants to see, but a reflection of what actually is there. A man can fool anyone, including himself, until, through his own eyes, he finds a reflection of his true self.
Everyone has a different perception than another, such a different perception that should be taken into account by other people. Whether people are blind or crazy, some people of this world are impaired so their lives are limited. The unknown can be very mind-boggling to these impaired people. Though at the same time there is a strong possibility that there are also even more unknown things to unimpaired people. Plato’s “The Allegory of the Cave” and “Seeing” by Annie Dillard suggest that knowledge and reality are both a matter of perception based on experiences; and as such, great care should be taken by anyone who attempts to redefine the perceptions of another.
“Everything we see hides another thing, we always want to see what is hidden by what we see. There is an interest in that which is hidden and which the visible does not show us. This interest can take form of a quite intense feeling, a sort of conflict, one might say, between the visible that is hidden and the visible that is present.” (Magritte)
... something when it fact, we never ask ourselves why we know it. We tend to take for granted what counts the most in this world, that is, knowing ourselves. Human beings think that knowledge of things will lead them to enlightenment. But in reality, it is nothing but an illusion made by man himself to create a kind of path towards success. Those who follow this path will get nowhere close to success, rather, they bring upon suffering along the way, pulling us farther from ourselves. Thus, if only we were aware of this deceptive nature of language and metaphor to that of knowledge, we would come to understand that truth indeed is nothing but a man-made word and is therefore a mere figment of our imagination. The facts do not count, only our interpretations of them. So it seems that Reality then isn’t so far from our dreams, perhaps it’s really the other way around.
However, when our vision is stripped from our secluded selves, reality is all you can truly “see.”
Sensation refers to the process of sensing what is around us in our environment by using our five senses, which are touching, smell, taste, sound and sight. Sensation occurs when one or more of the various sense organs received a stimulus. By receiving the stimulus, it will cause a mental or physical response. It starts in the sensory receptor, which are specialized cells that convert the stimulus to an electric impulse which makes it ready for the brain to use this information and this is the passive process. After this process, the perception comes into play of the active process. Perception is the process that selects the information, organize it and interpret that information.
Perception is defined as the process of organizing, interpreting, and selectively extracting sensory information . Visual perception is left to the individual person to make up their own mind. Perceptual organisation occurs when one groups the basic elements of the sensory world into the coherant objects that one perceives. Perception is therefore a process through which the brain makes sense of incoming stimuli.
Do you believe everything that you see? While some people may say yes and others say no, I believe that what you see is what you will believe. In this case, what does the quote “Seeing is Believing” even mean? "Seeing is Believing” means is that you will have to visually see something to convince your brain that what is visible to you is true. For instance, in a court, a judge will only believe that something is true if he or she sees it in front of them. Be it be the evidence, or being there to witness the crime. The only way they know for sure to make the right decision is proof, which is visual in almost all circumstances. Also, even though some of the things people believe may not be physically seen, they can be subjectively pictured. In the current unit we’re in, “Perception and Reality,” many of the authors show how the characters believe only what is visible to them like some of the examples above. The stories “Heartbeat” and “Magic and the Brain” portray this opinion.
A sense is a physiological ability of organisms that supply information for perception. Human receive stimulus energy from the external environment through the sensation process. Sensory receptor is found in sense organ which detect stimulus energy. They sense physical energy and decode physical stimulation into neural signals. Sight (opthalmoception),hearing (audioception), taste (gustaoception), smell (olfacoception) and touch (tactioception) are the five usually recognized senses.
We are what we imagine. Our very existence consists in our imagination of ourselves. Our best destiny is to imagine, at least, completely, who and what, and that we are. The greatest tragedy that can befall us is to go unimagined (Owens, 93).
Perception is defined as how you look at others and the world around you. Being able to select, organize and intercept information starts the perceptual process. Perception affects the way people communicate with others. An individual’s pattern of thinking can affect their perception of others. Most people communicate best with people of similar cultures.
“in order to think, it is necessary to exist, I judged that I could take as a general rule that the things we conceive very clearly and very distinctly are all true, but that there is merely some difficulty in properly discerning” (Descartes
The five senses of sight, hearing, touch, taste and smell are all sensations throughout the human body. Sensation is the involvement of sensory receptors as well as the central nervous system in order to allow us to experience outside stimuli. The system that allows us to experience sensation is the sensory system.
