“Hey, graffiti is an art. It is a way to express our feeling” someone replied. No, it is vandalism. Painting illegally on the wall, obviously it is vandalism!” A typical conversation most probably happened between a youngster and a grown up. Why are there such different opinions? The different of opinions is caused by the personal experienced. Someone older has more experience than someone younger. I believe that experience would be a major factor in human decisions. This cause that we, human see the things as we are, not as they are. We see what we want to see based on our personal or past experienced.
Sense of perceptions is usually the first way of knowing used by the human before they start to interpret the data and give their answers or opinion regarding the things they see. When a person start to ‘see’ the things, the nerve receptor of their organs will start to convert the data to impulse and the impulse (signal) are sent to the brain. It is at the brain, the things get more complicated. The brain will filter the signal received and start to translate the signal received ‘as we are’. The translated signal will initiate stimulus (reactions to the surrounding) or opinions. Most complications occur usually involving the past experience of the person. For example, some people said that Bungee jumping is fun. But, other people who are afraid of height (acrophobia) will say that it is reckless and totally dangerous. This may be caused by the traumatic experience that he or she had gone before. This means that the acrophobic person viewed the Bungee jumping as we are, and not as they are.
The other ways of knowing involved is logic. As we pass through the, we are actually explore the way we reason  . When it comes to the deductive logic, humans actually making conclusion and assumptions from the arguments. The conclusion is drawn from the arguments stated by the human before. Most of the arguments drawn from the human past experience. After the arguments, conclusion are made and also based on the past experience. Through deductive logic, the human see the world as we are and not as they are. Human use their experienced to see things differently from as they are.
Emotional moment usually associated with the condition where someone is under pressure and unstable. The emotions ways of knowing are rarely chosen as the best solutions to view as opinions. This is because the decisions based on the solution are usually out of mind. Intuition is one way of knowing using emotion. Based on the dictionary, intuition means the ability to know something by using your feelings rather than considering the facts  . Which emotion is different from logic. The main source of intuition is experience, you know someone’s action because you have been with him or her for years. For example, you know that you are in love because you have fallen in love before. The feeling of falling in love are different from any other feeling. Our feelings are really subjective. This is proving more that the way we see through the experience prevent us to see the thing as they are.
Natural Science is the study of natural phenomena that occur around us. Through natural science, we are able to predict the weather, to mine gold, to locate natural gas or even create vaccination for TB. Natural Science is an area of knowledge that uses a lot sense of perception and logic. The experiments in the natural science are conducted by the scientists and for centuries, experiments have been the best way to prove the knowledge claim by the scientists. The experiments are conducted based on the basic scientific methods that have been used for centuries. The methods involve observation, information, generalization, theory, explanation and prediction  .
Observations involve using the sense of perception. The scientist used up the five senses to observe and record any observations. During the observations, the limitations had started. Our mind set to observe what we want to see. For example, if the scientists want to investigate about the change in temperature, scientists always manage to find the temperature. But, they tend to ignore the pH change, the colour, the smell or any sound produce.
After using the observations, the scientists start to make generalization and theory. These involve the inductive logic. They used up the inductive logic to make any inference, hypothesis and theories. Those inductive logics come from the past experience and mapped with the current situation or experiment. The scientist usually does not take into account any knowledge other than their past experience. After that, the inductive logic is used again in deductive logic as an argument. This will create further knowledge of ‘what we want’ in the experiment. The deductive logic is use to make explanation and prediction. The inductive logic is applied as the arguments in the deductive logics. So, the deduction or the hypothesis is mostly made based on the past experience. The scientist only search for what they want. Hence, they tend to follow the deduction they have made earlier. The experiment is a success if the result parallel or same with the expected result (deduction). The experiment is considered a failure if the result do not support the deduction.
What would happen if a science student carry out the same experiment. Would they get the same result? They only learn the theory made by the previous scientist. Those are the facts (as they are) that they need to accept. They did not have much experience. So, they will see the experiment through the eye of previous scientist, for example theory of energy made by Albert Einstein, E = mc2.
Music is another branch in the Art area of knowing, musician interprets things differently from scientist. In music, each famous composer has their own way of composing their songs, and pieces. Like Mozart, he travels a lot in order to produce great music. Some of them may go to the famous place for music such as Prague or Vienna. These are the place where famous composers like Brahms, Beethoven and Mozart are made. As their pieces are really famous nowadays, various people interpret their music differently. Human translate music into knowledge using sense of perceptions and emotions.
Using sense of perceptions, human use the hearing sense to hear to the music played. After that, human start to listen. When they hear, the ear receptor send stimuli to the brain and brain will start to translate the stimuli to stimulus. When the human start to listen, mixed feelings are produced and it is unable to translate into language. Normal human would only hear the music is normal. How we feel affects of what we see  . If the person has their emotions associated with the songs, they would have mixed feelings and started to cry or laugh. The emotions come from their past experience. They remember about something that happened to them in the past and relate it to the song they hear. We can also compare with someone with someone who learn music (musician) and non-musician. The musicians actually enjoyed and appreciate the music more compared to the non-musician people. The musicians would always know whether the music is good or not. We might hear musical orchestra as a very bored music, but to musicians, the music is good and wonderful song. The musicians actually use their past experience to judge the song. They know the real characteristic of a good song. They learn it before, so, to the musician, a good music may comprises of good composition of the song and correctly played while on the stage.
Although the natural science field involves a lot of perceptions and logic, emotions may involved as the scientist are all human. Human have feelings. During concluding, the scientist might have biases and does not even accept certain findings in the. They have their own boundary such as culture and religion. For example, Islam does not allow cloning, so any scientist in Islam would deny the benefits of cloning. For instance, although music more towards emotions and perception. The use of logic in reason cannot be denied. In singing competitions, the judge would judge the contestants based on the allocated marks. The judge will give marks based on their voice, vocal, pitching, lyrics or performance. Most of the factors involve deductive logic. This means that, if the singer obtained high score, the singer will win.
As I am going through my essay, I found out that human would always have different perceptions and view. Human brains are all the same, what always differ us is the experience that are obtained by us. Our own experience makes us see things differently from each other. We tend to see things as we are and we always ignore the thing as they are (facts).
