10. 'Through different methods of justification, we can reach conclusions in ethics that are as
well–supported as those provided in mathematics.' To what extent would you agree?
One could argue that mathematics and ethics are the underlying essentials above which our society
has based itself. Scores of cities have built their infrastructures using measurements and methods
founded in mathematics. Our inherent ethical natures have catalyzed the great minds from ancient
civilizations to create democracies, and have enabled our generations to uphold these same moral
principles. While both these studies are so readily used today, when comparing them it is essential in
understanding at the same time the disparity between the two subjects. The...show more content...
Using whichever ethical lens that you feel encompasses your morals/values (deontology,
utilitarianism, altruism, etc.), you can ultimately reach sound conclusions. But even so, there are so
many more aspects to consider, especially when dissecting an ethical issue. So how can we then
determine any "general" conclusions to ethics? By this, I am in essence making a referral to some
sort of a general consensus to a universal query. It is up to the individual who is asked, is it not, on
how they perceive the argument, and how they react to it? Can we therefore begin to view ethics as
an intrinsic human reaction, a way of immediate analysis, or even the societal expectation that we
carefully scrutinize every situation placed before us before concluding? This unique interpretation
of ethics could completely reform how conclusions are made and what they might entail. If we take
for example abortion, it is known that abortion is not a subject in which there are clear–cut
solutions. I stand firmly with my belief that the choice of abortion is rightfully entrusted to women,
but then again, I share a personal connection with this abortion issue. My mother, who in every way
is my idol, has a sickness which inhibits her body's ability to function at certain times. Three years
ago, she became pregnant. Doctors predicted disabilities the baby could have due to medications my
mother was taking. I admire my mother for her courage and

TOK Knowledge Essay
The claim "Knowledge is nothing more than the systematic organization of facts," has many flaws
in its implications. All of the knowledge that we gain as ToK knowers cannot be considered
infallible fact. The term "fact" implies that the statement or claim can be reinforced with substantial
evidence and can be proven, and we have learned that almost any information can be considered
knowledge, no matter how subjective or specific the information is. Given that an individual is
defined by having a specific and unique way of thinking and perceiving the world, most of the
knowledge gained in several different Areas of Knowledge are heavily dependent on the
perspectives of the individuals under examination. Both the Areas of Knowledge of Ethics and
Human Sciences have many ambiguities when it comes to organizing and legitimizing this data.
This leads the knower to ask, "What makes information factual in terms of ToK knowledge?" It can
be proven through Ethics and Human Sciences that knowledge is not the systematic organization of
facts, but the systematic organization of collective data to show trends and patterns. Ethical
boundaries and impressions are subjective to every individual, and the public ethical boundary must
be based off of the accumulative average of the environment. There is not a factual "This is right"
vs. "This is wrong" because no single human being has the authority to make such a statement. In
fact, it is this basic ethical disagreement that has led to

Tok Sense Perception
To what extent is sense perception a good foundation for reliable knowledge?
Sitting in this classroom today, I can see different things around me, smell different smells around
the room, feel the keyboard underneath my fingertips, taste the apple I had during lunch and hear
all the different sounds coming from all different people in the room. I can say I know this to be
true because we perceive the world through our five senses: sight, sound, taste, touch and smell.
Knowledge is what we learn, what we gain from our own experiences and what we understand from
other people's interpretations. Our senses provide us with a journey, which we are able to take or
reject.
Trusting our senses comes so naturally that we don't realize what...show more content...
Appearance and reality can be very tricky to distinguish. I remember asking myself last month
when I was very happy, is this real, or is this what I want my life to be? Without knowing, without
realizing we prove to ourselves what is real and what is not by using the tests truth. When I was told
about this, I didn't even know what the tests of truth were. The first one is confirmation by another
sense, if something looks like an apple and tastes like an apple, then we would conclude that its an
apple. The reason we would use this is if one of our sense are wrong, like for example dry ice, when
you look at it is steamy so we would say that it is hot, but in fact if you touch it, it is cold.
The second test of truth is coherence. When you see something that doesn't fit into what you
expect from experience of the world then you are most probably mistaken. For example when I
was a little kid I used to spin around in circles until I was dizzy, and when I stopped I used to see
the world spin around me. Although when I was not dizzy I knew that, that wasn't true. Finally the
third test of truth is independent testimony, testimony of other people. For example when I have
put my mom's phone on the table and I have seen it there, and when my mom asks for it, and its
not on the table I ask my brothers and sisters to prove that they saw it there as well and my mom is

Essay Magnetic Resonance Imaging
Magnetic Resonance Imaging
Magnetic resonance imaging has the potential of totally replacing computed tomography. If history
was rewritten, and CT invented after MRI, nobody would bother to pursue CT.––Philip Drew
(Mattson and Simon, 1996)
WHAT IT IS
Magnetic Resonance Imaging, or commonly known as MRI, is a technique used in medicine for
producing images of tissues inside the body. It is an important diagnostic tool because it enables
physicians to identify abnormal tissue without opening the body through surgery. MRI lets
physicians see through bones and organs. MRI does not expose the patient to radiation, unlike tests
that use X–rays. MRI provides an unparallel view inside the human body. It is the method of choice

MRI AND BEYOND
MRI technology is still in its infancy. The first MRI exam on a human being ever taken was on July
3, 1977. MRI has been in widespread use for less than 20 years (compared with over 100 years for
x–rays). There is still a long future for MRI. It is only the beginning. We can now image in seconds
what used to take hours.
Here are a few of the developments:
1. Very small scanners for imaging specific body parts are being developed.
2. Functional brain mapping (scanning a person's brain while he or she is performing a certain
physical task such as squeezing a ball, or looking at a particular type of picture) is helping
researchers better understand how the brain works.
3. Research is under way in a few institutions to image the ventilation dynamics of the lungs through
the use of hyperpolarized helium–3 gas.
4. New, improved ways to image strokes in their earliest stages is ongoing.(

SOCIETAL IMPACTS
ADVANTAGES & DISADVANTAGES
There are always going to be advantages and disadvantages in anything that is developed in the area

of technology. MRI is no different.
MRI is ideal for:
1. Diagnosing multiple sclerosis (MS)
2. Diagnosing tumors of the pituitary gland and brain
3. Diagnosing infections in the brain, spine or joints
4. Visualizing

Plato's Theory of Knowledge Essay
Plato's Theory of Knowledge
Plato's Theory of Knowledge is very interesting. He expresses this theory with three approaches: his
allegory of The Cave, his metaphor of the Divided Line and his doctrine The Forms. Each theory is
interconnected; one could not be without the other. Here we will explore how one relates to the other.
In The Cave, Plato describes a vision of shackled prisoners seated in a dark cave facing the wall.
Chained also by their necks, the prisoners can only look forward and see only shadows, These
shadows are produced by men, with shapes of objects or men, walking in front of a fire behind the
prisoners. Plato states that for the prisoners, reality is only the mere shadows thrown onto the wall.
...show more content...
Plato considered shadows, art and poetry, especially rhetoric, deceptive illusions, what you see is
not necessarily what you get. With poetry and rhetoric you may be able to read the words but you
may not understand the "real" meaning. For example, take, again, the shadow. If you know a
shadow is something "real" then you are beyond the state of imagination which implies that a
person is "unaware of observation and amounts to illusion and ignorance". Belief is the next stage
of developing knowledge. Plato goes with the idea that seeing really is not always believing we
have a strong conviction for what we see but not with absolute certainty. This stage is more
advanced than imagining because it's based more firmly on reality. But just because we can
actually see the object and not just it's shadow doesn't mean we know all there is to know about
the object. In the next stage, Thinking, we leave the "visible world" and move into the "intelligible
world" which, Plato claims, is seen mostly in scientists. It stands for the power of the mind to take
properties from a visible object and applying them. Thinking is the "visible" object but also the
hypotheses, "A truth which is taken as self–evident but which depends upon some higher truth".
Plato wants us to see all things as they really are so we can see that all is inter–connected. But

Tok Emotion Essay
Veruska M. B. November 18, 2011 TOK Mr. de Silva Grade 11 OSC TOK Essay: How do
Perception and Emotion Contribute to our Knowledge of the World? Perception is broad concept,
often defined through various contexts. Similarly, emotion has assorted definitions. These concepts
differ in their timing in the world, for without the initial perception, emotion is a non–existent
concept. And without such commodities our knowledge of the world would cease to exist. For our
perception and emotion influences the other ways of knowing (WOK) immensely such as reason
and language. Perception is how we perceive our surroundings, and the world. It's often defined in 5

My emotion of sadness, led me to believe that my mother must be lying to me, because the
sadness and anger obscured the truth. I was so absorbed in emotion and denial. On Monday, I
waited at the bus stop and missed two of my classes. My judgment was so clouded; I simply
rejected my perception, my knowledge, because of my strong emotion. Because of all the
happiness Simon brought me, I could not let him go. Having it been so long ago now, I have a
different emotional response whenever Simon is brought up. The emotion of sadness is still there,
but it does not cloud the knowledge I gained from the experience of the loss. In conclusion,
perception and emotion contribute to our knowledge of the world, in both its filtering of knowledge,
and its positive reaction. Emotion and perception can both suppress knowledge not wanting to be
obtained in a moment of strong emotion. But it can also be a strong positive influence in an area of
creativity and individuality. The examples of art class and the death of Simon both exemplify such
occurrences in my knowledge of the world. Works Cited Brennan, Samantha. "Thinking Positive".

Possession of Knowledge Tok Essay
TOK Outline
Essay title – "The possession of knowledge carries an ethical responsibility". Evaluate this claim.
What knowledge issues I think are involved
How can you possess knowledge? How do you acquire it and do these ways affect your
responsibility of imparting it on others?
How is the knowledge you have affected by your personal ethics? Some people would have no
problem giving out certain pieces of knowledge while others would be very trouble giving out
exactly the same information.
How can one know when they are ethically responsible? How do you know how big the impact of
the knowledge you are giving will have on the recipient?
Ways of knowing, Areas of knowledge that are involved.
Ways of knowing o Reason – Has...show more content...
4th Paragraph
Same as 2nd paragraph except with second area of knowledge – Natural and human sciences.
Biology – example would be Ben Johnson at the 1988 olympic. Doctors ethical responsibility to give
him the drugs knowing their effect and the details while Ben Johnson just trusted his professional
ability.
Economics – Bank crisis in 2008. Did the banks have an ethical responsibility to tell the public that
their money was being used for other things, instead of just letting the money be lost and telling
them after they had invested it all.
5th paragraph
Explain how ways of knowing will be linked to the claim – Reason
Provide example. o If someone stops you on the street and asks for directions then you use reason to
determine that it seems perfectly fine for you to impart the knowledge you have and that it coincides
with your ethics.
6th paragraph
Same as above with other way of knowing – emotion o A doctor giving the results of tests to a
patient and telling them that they are terminally ill. They may not want to impart that knowledge as
they know it will greatly affect the person and emotionally you wouldn't want to be giving that
information. But they are ethically responsible as professionals to give that information. o Another
example that would go with this is a police officer having to tell the next of kin that they family
member has died.
Conclusion
Evaluate all the points that have been talked about.

A model is a simplified representation of some aspect of the world. In what ways may models help
or hinder the research for knowledge?
A model by definition is "a schematic description of a system, theory, or phenomenon that
accounts for its known or inferred properties and may be used for further study of its
characteristics"(source) that implies that a model is supposed to be a helping hand while
searching for knowledge in any subject. Sometimes however models can appear to be quite
confusing as they are to general or too far away from real life situations. So how and in what way
models can help and hinder the search for knowledge in natural sciences, human sciences and arts I
am going to argue in the following essay.

However the models of art only help us in the search for artistic knowledge. However logically
anyone can differentiate between a Picasso and a Monet as the differences are easy to be seen but it
takes a lot of study to empirically know the different models.
That means we can only understand and use the models if we understand art so to a normal
human being that does not want to have a deeper knowledge about art and its backgrounds and
the fine borders between the styles those models are useless. In this case they are too subject
specific for someone to use. Models can also be interpreted as being rules about how to specifically
draw or paint something so that it is art. A good example for that is theMona Lisa by Leonardo
DaVinci. Although he drew a women in a realistic way, her eyebrows are missing, which lets
people detach from the painting emotionally as she seems less human in a way. In the Arts
models can also be something different. A very good example for that would be the Mona Lisa
by Leonardo DaVinci. His model we assume was a woman or a man that must have looked just
like an everyday person, however DaVinci whether on purpose or not left out any emotion and lets
the person appear extremely emotionless and cold. In this way the art work hinders us from
knowing more about the intentions of this painting and also about the person being drawn. However
this is a trigger for people to want to find out more about this painter and
