DAY 55 - Empiricism and two-brained dinosaurs....

Had to include this poem from the late 1800s.  It was published when new "evidence" indicated that the Stegasauri family of dinosaurs had a second brain near the base of it's spine near the hip.  Much was made of this new discovery but it is now thought that the enlarged cavity did not contain a second brain.  We think that it contained excess nerves and fluids, likely glycogen, as a "battery backup" for bursts of energy, clearly for a purpose other than thinking!  How often do you see clear philosophical terms in poetry?

The Riddle Of The Dinosaur - Bert Taylor

Behold the mighty dinosaur,
Famous in prehistoric lore,
Not only for his weight and length,
But for his intellectual strength.
You will observe by these remains
The creature had two sets of brains,
The one in his head, the usual place,
The other at his spinal base.
Thus he could reason a priori
As well as a posteriori.
No problem bothered him a bit,
He made both head and tail of it.
So wise he was
So wise and solemn
Each thought filled just a spinal column.
If one brain found the pressure strong,
It passed a few ideas along.
It something slipped the forward mind
’Twas rescued by the one behind.
And if in error he was caught
He had a saving afterthought.
As he thought twice before he spoke
He had no judgment to revoke.
For he could think without congestion
Upon both sides of every question.
O gaze upon this noble beast,
Defunct ten million years at least.

Day 53 Empiricism

No man's knowledge here can go beyond his experience.  

John Locke (1632-1704)

Can you imagine plummeting from the sky at 300 km/hr? What would you experience? The wind tearing through your hair. Your friends screaming in your ears. And of course, the sight of the earth growing steadily closer would be a key component of the experience.

Rationalists might suggest you close your eyes and imagine the sensations, but can that really compare to actually experiencing it? As you will discover, empiricists argue a clear "no!"

1. And Now For Something Completely Different...

Consider this ancient Chinese proverb: 'Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime'.

So how do you teach a man to fish? Rationalists would, of course, argue that the man can simply close his eyes and rationalize his way toward understanding.

Empiricists, however, disagree. They would tell the man to go with someone who knows how to fish and practice the art.

After all, if you ask most people how they learn, they will probably tell you by experience. And this makes a lot of sense. Every day you go out into the world you are awash in sensations, some of which you attend to and some of which you do not. Nevertheless, when attended to, these sensations become experiences, and then, in turn, these experiences become knowledge. So, for empiricists, how you know something is through real-world experiences.

Key Empiricist Philosophers

Sophists     Aristotle     Aquinas     Bacon     Locke     Berkeley     Hume     Russell

Please check these links and take a note or two about each - if you can find a direct quote, even better!
In addition, please look at pp. 209 - 213 to look specifically at what some of these philosophers said and thought.

Sophistry!

Nowadays, saying someone is using a sophist argument is an insult (go ahead, try it); it suggests that the speaker is using persuasive techniques, rather than sound arguments and evidence, to sway the listener. No doubt you've seen evidence of this in your classes when homework assignments lie forgotten at home...

However, the original sophists were among the first Western empiricists. They denied rationalist arguments in favour of concrete experiences. Of course, given their 'pay-for-say' outlook this is not surprising. After all, people have a much more emotional connection to experiences than to rationalized thought experiments.

If you want to learn more about the Sophists, click here to read Plato's dialogue entitled "Sophist". Be forewarned, Plato was NOT a fan of the Sophists!

2. A Blank Slate

Perhaps you have heard of this term before. What do you think it means? Well, if you're an empiricist, it is a central cornerstone to your theory of knowledge. Let's consider some of the famous statements made about it:

Aristotle

"What the mind thinks must be in it in the same sense as letters are on a tablet which bears no actual writing; this is just what happens in the case of the mind."

Aquinas

"But the human intellect, which is the lowest in the order of intellects and the most removed from the perfection of the Divine intellect, is in potency with regard to things intelligible, and is at first "like a clean tablet on which nothing is written", as the Philosopher [Aristotle] says."

Locke

"Men, barely by the use of their natural faculties, may attain to all the knowledge they have, without the help of any innate impressions, and may arrive at certainty without any such original notions or principles."

Basically, Empiricists say that you are born with a practically empty mind (practically, since most philosophers argue an awareness of God pre-exists) upon which all of your experiences and sensations write your memories, and thus knowledge. You are not born knowing anything. It is what you do that makes you who you are. If this is true, then rationalists must necessarily rely on experience to fuel their inward reflections.

However, this runs contrary to some basic understandings of human nature. Babies, for example, are born knowing instinctively how to suck and grasp. Likewise, insects are born with enough genetic knowledge to be born, survive, thrive and spawn. In fact, psychologist Carl Jung went so far as to suggest humanity had a shared collective unconscious, whereby the memories of all our past ancestors were stored. How does this affect an empirical weltanschauung?

Did You Know?

Although our experiences provide a rich tapestry of memory to recall and enjoy, metaphysics forces you to wonder whether they are, in fact, real. And while the prospect of being a brain in a vat is distressing, it cannot be fully discounted.

However, you need not go to science fiction movies for this. In the 1930s, Canadian neurosurgeon Wilder Penfield's experiments with open brain surgery on seizure victims resulted in vivid sensation stimulus recalls by only stimulating parts of brain tissue.

The famous cry "I smell burnt toast!" occurred when Ms. Phoebe Stanley's brain was exposed and probed by Dr. Penfield. This helped Penfield locate where our memories were stored in the brain.

3. Contemporary Applications

Have you ever wondered what you can "do" with philosophy (other than amuse and annoy your friends of course)? Well, empiricism is a great example of how philosophy and the "real world" intertwine.

Whether they refer to themselves this way or not, most scientists are empiricists. They rely on experiences to create, define and refine their theories. Likewise, lawyers, psychiatrists, mechanics and sports stars are also empiricists. Can you see how?

DAY 42 - Rationalism (How Do You Know?)

The beginning of knowledge is the discovery of something we do not understand.

Frank Herbert (1920 - 1986)

Modern medical science has permitted people to look inside your brain and measure your very thoughts. Through magnetic resonance imagining, the secrets of the mind are finally laid bare.

Or are they? Can a machine see your thoughts, or, like hot breath on a cold day, merely hint at what is there?

Here's what these machines can see...

1. Be Rational...

You've probably heard (or used) the plea 'be rational'. Usually, this phrase invites people to pause and consider - often when their arguments are overly emotional. However, for philosophers, this phrase acts as a cornerstone for one of the two largest schools of thought - rationalism.

Rationalism is based on the premise that, through reason alone, you can understand necessary and significant truths about the universe and the self. To a rationalist, experiences may help focus your mind, but these experiences don't teach you anything.

2. Use Your Imagination...

Here's another term you've probably heard; it is used to evoke creative ideas or unique perspectives. However, for philosophers, the imagination becomes a powerful tool in the search for truth. Indeed, the concept of a thought experiment itself uses your imagination to develop and evaluate hypothetical ideas. Remember: Einstein's theories of relativity didn't come from experimentation...they came from his imagination!

Characters like Barney over there helped to stimulate your imagination when you were young.

Did you know?

Have you ever gotten a headache from listening to other people complain about their headache?

If so, you may have suffered from a mild version of a psychosomatic illness; that is, a physical aliment brought on by a mental or emotional stimulus. Psychosomatic illnesses derive from the mind, but can manifest themselves physically. In other words, the mind shapes reality.

Another scientific example is the use of a placebo. A placebo occurs when a non-medical treatment is provided; this can either be without the subject's knowledge or with the subject incorrectly believing they are receiving the actual treatment. Placebos are used to test the degree of impact medicines and treatments have on patients.

However, there is also evidence that the placebo itself is enough to cause significant changes in a patient's mental or physical state (more commonly called the Placebo Effect). Again, this shows that belief alone is enough to alter reality. Can you recall the phantom limb syndrome? When a person who loses a limb sometimes they have the sensation, feeling or belief that their absent limb is still attached - a phantom limb.

1. History of Psychosomatic Illness
2. Latest Research on the Placebo Effect

But can your imagination show you truth? Certainly, some things you imagine are not true. For example, you can imagine a unicorn, but they aren't real. Or are they?

Well, according to Plato, yes. Or at least, the Form is. You see, Plato believed that the world consisted of two separate, yet related existences: the World of Becoming (material) and the World of Being (immaterial). In the World of Being, the Form of a horse is the perfect, ideal representation of it. This was never achievable in our material world, which is why there is variety, both real and unreal. However, for Plato the true Form does exist and is, in fact, more real than our material 'reflections'.

Another, more famous, example is that of a triangle. Try drawing a triangle. How does it look? Is it perfect? What is perfect? Wouldn't perfect mean that the lines were perfectly straight and had no thickness? Is that even possible?

Plato argued that it was not. Yet, he still held that the World of Being was real, if something we could not physically access.

3. Plato's Cave

Imagine being born in a cave, unable to move, facing away from the opening. What would you see? Well, if it was daytime, you would see shadows (from people, animals, clouds, trees, etc) move across the wall you're facing.

How would this alter your reality? What would be true to you? And would it indeed be true?


In Plato's Cave, the World of Becoming and World of Being are examined using the allegory of people who grow up knowing nothing but flickering shadows on a cave wall. For these 'prisoners' the cave wall represents their only connection with reality - a reality that is less real than our own reality. After all, even at an early age you knew your shadow was not real.

Yet, these flickering images on the cave's wall make up the sum total of all their knowledge about the world. Later philosophers have examined the impact this weltanschauung had on their personality, language, development, social structures, etc. However, Plato merely used these unfortunate captives as a metaphor for the World of Becoming. The truth, then, was represented by the sunlight pouring into the cave's mouth - the World of Being. Sadly, Plato believed that most people spent all of their time trapped in their own materialistic mindsets, and so could neither know nor imagine a world different from their own... Does this worldview sound like anything contemporary? (Hint: look below).

DAY 41 - So, What Do You Really Actually Know?

I know nothing except the fact of my ignorance.          Socrates (469 BCE - 399 BCE

Knowledge Is Power

At a 2002 NATO press conference, in response to a question regarding the absent WMDs (weapons of mass destruction) in Iraq, then Secretary of Defence for the US Donald Rumsfeld replied: "Now what is the message there? The message is that there are no "knowns." There are things we know that we know. There are known unknowns. That is to say there are things that we now know we don't know. But there are also unknown unknowns. These are things we don't know we don't know. So when we do the best we can and we pull all this information together, and we then say well that's basically what we see as the situation, that is really only the known 'knowns' and the known 'unknowns'. And each year, we discover a few more of those unknown unknowns."

Secretary Rumsfeld Press Conference at NATO Headquarters, Brussels, Belgium (June 6, 2002)

What does it mean to know something? Dictionary.com defines 'know' as:

1. To perceive or understand as fact or truth; to apprehend clearly and with certainty: I know the situation fully.
2. To have established or fixed in the mind or memory: to know a poem by heart; Do you know the way to the park from here?
3. To be cognizant or aware of: I know it
4. Be acquainted with (a thing, place, person, etc.), as by sight, experience, or report: to know the mayor.
5. To understand from experience or attainment (usually fol. by how before an infinitive): to know how to make gingerbread.
6. To be able to distinguish, as one from another: to know right from wrong.
7. Archaic. to have sexual intercourse with.
8. To have knowledge or clear and certain perception, as of fact or truth.
9. To be cognizant or aware, as of some fact, circumstance, or occurrence; have information, as about something.
10. The fact or state of knowing; knowledge.

Of course, knowing something is different from knowing how to do something. And neither is necessarily easier than the other. In the next two activities, you will be examining the nature of knowledge from two competing perspectives: rationalism and empiricism. However, before you begin identifying what and how you know something, first you must determine what it is you know.

So what do you know?
To find out, try this experiment. Take 2 minutes and write out everything you know. Don't stop to think, just let the ideas flow freely. Use a watch to time yourself or if this is during class I'll time you.

So what did you write down? Was it a jumble of random information or was it on a single topic? Did you use any organizational scheme or simply jot down points linearly?

No matter how you wrote out your information, odds are you didn't manage to write everything you know. That's because you've collected a HUGE amount of information, and continue to add to that storehouse each and every day. In fact, at times it may seem like you know everything (or, at least, your parents might say that's what you think). Unfortunately, you can't. Sorry. Why not?

Well, the answer is simple: perspective.

You see, you see. But only you. You can't, for example, with all certainty see your friend's perspective. Sure, they can tell you what they know, think or feel, but how can you be absolutely sure you understand exactly what they mean?

As the image depicts, your knowledge may both be light, but your perspectives filter and change the outcome.

2. Flat Earth Society

Are you worried you might know too much? Have no fear (or any ideas for that matter)! The Flat Earth Society is here. Operating since the mid-eighteenth century, this group holds that the Earth is indeed flat - after all, when you look out your window does the Earth look round?

To learn more about the Flat Earth Society and its mission click on the link.

However, despite this rather eccentric group's outlook, the idea of a round Earth is a relatively recent conception. 500 years ago most people believed the Earth was flat, simply because both personal observations coupled with societal common sense told them it was. However, with advancements, experiments and revision came a new conclusion: the Earth was, in fact, round! No wonder Socrates suggested he knew nothing...after all, how long can you be certain your current knowledge will be correct?

Or, to quote Agent K from Men in Black,

"A thousand years ago everybody knew as a fact, that the Earth was the center of the universe. Five hundred years ago, everybody knew that the Earth was flat, and fifteen minutes ago, you knew that humans were alone on it. Imagine what you'll know tomorrow."

End Scene of Men in Black.

How Well Do You Know Yourself?

There are thousands of personality tests available online that aim to unearth some hidden knowledge about who you are. Whether Freud's focus on sexuality or Skinner's suggestion that behaviour determines personality, the goal is the same: discovering what people have in common and who you are. Some psychological tests - such as the Rorschach inkblot test - have not stood the test of time. Indeed, many people give personality tests with the same credence as they would horoscopes.

Other tests, however, continue to emerge, and thousands of new psychology students enter the profession each year. What else could explain this but the drive to discover some hidden knowledge about ourselves?

So, why not try a personality test out for yourself? Click here to take a free personality test. This test is based off of Carl Jung's personality types, and is still widely used today. After taking the test, click here to find out a detailed analysis of your Myers-Brigg personality type.

Did you find that the test supplied you with any new knowledge about yourself? If so, what? If not, why not?

DAY 40 - Epistemology - Socratic Discussions. What Do You Believe?

I would never die for my beliefs because I might be wrong.       Bertrand Russell (1872 - 1970)

Thomas Paine proposed that "I offer nothing more than simple facts, plain arguments, and common sense...".

Sounds good right? 

People talk about common sense all the time. No doubt, someone has chastised you for not using common sense. But what is common sense exactly?

Common sense is a commonly shared (communal) understanding of an idea, issue or outcome. Its validity lasts as long as the group that espouses it continues to. When used and agreed upon, it confirms and supports the shared belief. Can you think of anything that you would call 'common sense'?

1. It's Common Sense

Einstein suggested that "Common sense is the collection of prejudices acquired by age eighteen". So is common sense a valuable source of knowledge? Well, that depends on how it is utilized. After all, it's common sense to avoid running into traffic without looking. But is that true knowledge? And does it matter?

Well, that too depends. On the surface, common sense doesn't appear too convincing as true knowledge. However, for thousands of years societies have relied on common (communal) sense to function. Over time, many of those aspects of common sense became codified into laws while others remained unwritten but known to all. The Kiriwina of New Guinea have a word - mokita - which means 'the truth which no one speaks'.

2. An Eye for an Eye

The Code of Hammurabi is one of the oldest, written legal codes. Written in 1760 BC, it lists 282 laws. King Hammurabi purposefully inscribed the laws in stone to illustrate that they were now immutable and unchanging, and that even a King was bound to them.

However, most of the laws themselves are common sense transcriptions; however, to ensure their compliance, the punishment was often death.

3. "I'd Like a Second Opinion"

Philosophers rarely rely on opinion as knowledge. The reason for that is clear: opinions vary. For example, a teacher might believe your friend hates class because they sleep in, but you know they are tired because they need to work to support their family.

Yet, opinions are important; after all, they add variety to the human experience. When you visit a doctor, you can ask for a second opinion. Does this suggest the first doctor is wrong? Not necessarily, it is just that there could be other, better options available. This, then, demonstrates how knowledge and its application is a complex, difficult issue.

Nonetheless, opinions can also be suggestive, misleading or wrong.

4. "Wikiality" and You

It's difficult to deny that Wikipedia has changed the way people access information. With a simple site and search, millions of articles become immediately accessible. When was the last time you wrote a research paper without using Wikipedia? As far as ease of use goes, Wikipedia works!

But can you trust Wikipedia? Did you know that it is flawed? You may, in fact, be reading and perpetuating tainted common sense! You see, Wikipedia is an open source encyclopedia; in other words, anyone can edit and alter articles. In most cases, this is a good thing since it allows for experts around the world to conveniently share information.

Unfortunately, not everyone holds to these ideals. Since Wikipedia is open source, information ranging from small mistakes to outright lies have been posted.

If you still have your doubts consider:
After introducing the word 'wikiality', Steven Colbert encouraged viewers to edit Wikipedia to report that the number of African elephants has tripled in the last six months. And the information was revised in accordance with this incorrect trivial information.  Click here for Colbert's Ideas.

Can You Trust Wikiality?
Seigenthaler incident,

4. Opinions vs. Beliefs

Philosophically, Epistemologists are more willing to accept beliefs over opinions. Unfortunately, for many people the words are mere semantics. Statements of belief can be true or false, while statements of opinion (as you read above) cannot necessarily be slotted into true or false categories. However, justified true beliefs are often considered knowledge.

A justified true belief requires three conditions:

1. The statement is true;
2. You believe the statement is true;
3. You are justified in believing the statement is true.

For example, you could make a knowledge claim that marshmallows are soft if (if and only if):

1. Marshmallows are soft;
2. You believe marshmallows are soft;
3. You are justified in believing marshmallows are soft.

Required Reading

In his dialogues, Plato often explored the nature of knowledge. In his famous work Theaetetus, Plato had Socrates discuss whether knowledge from belief can be counted as true.   I want you to have a sense of what this work looks like, that it's a lengthy dialogue between two people and demonstrates the power of the Socratic Method.

Next go here and read a bit under each of the main headings.  This site discusses the meaning behind short passages of Theaetetus and is a great source for some worthy quotes for your note-taking for future reference!  Don't miss this opportunity!

Gettier Problem

Although the concept of justified true belief was accepted for centuries, in 1963 philosopher Edmund Gettier introduced a snag. Basically, he was able to show how someone could make a claim that fit the criteria for a justified true belief and yet still be wrong. Can you think of an example?

Click here to read Gettier's short but influential paper.

5. Truthiness

On his program, the "Steven Colbert Report", Steven Colbert drew attention to the common sense concerns that arise in a media-rich word. In the Merriam-Webster's Words of the Year 2006, truthiness is defined as:

1. "truth that comes from the gut, not books" (Stephen Colbert, Comedy Central's "The Colbert Report," October 2005),
2. "the quality of preferring concepts or facts one wishes to be true, rather than concepts or facts known to be true" (American Dialect Society, January 2006)"

Colbert's Report on Truthiness.

Truthiness is tearing apart our country, and I don't mean the argument over who came up with the word. I don't know whether it's a new thing, but it's certainly a current thing, in that it doesn't seem to matter what facts are. It used to be, everyone was entitled to their own opinion, but not their own facts. But that's not the case anymore. Facts matter not at all. Perception is everything. It's certainty.  What do You think?

DAY 39 - What Is Epistemology cont'd

"All truths are easy to understand once they are discovered; the point is to discover them."

Galileo Galilei (1564 - 1642)

What do you see when you look at this next two images? 

A horse of course!

And what do you see here?

Exactly!  A frog from Prague.

Well part of what you see depends on your weltanschauung (remember worldview?). But which one is it, a horse or a frog? Obviously, both. Through this example you see (no pun intended), how your perspective changes the truth.

Same picture(s), different angles:

So, at what point did it become more horse and less frog when viewed left to right?  Right to left?

In this unit, you will be expanding your ability to see different perspectives as you attempt to uncover the truth about...the truth!

Epistemology:

1. Introduction

After studying Metaphysics you might be wondering whether you can know anything for certain (remember Descartes and Hume?). Or, more cynically, what's the point? After all, if nothing can be known for sure, then why bother studying philosophy at all?

Sadly, many people end their philosophical journey there. Fortunately, some people are less deterred and continue onward, seeking wisdom for the love of the quest.

Whether you know it or not, epistemology affects you every day. For example, imagine a friend dings you online and tells you that someone at school likes you. You may take what they say at face value, or you may question whether it is true or not. After making that decision, you must decide how you intend to respond. Or, consider this: you are a juror and your answer to the question "guilty or not guilty?" will alter a person's life forever.

Epistemology is the search for truth and knowledge - not just in attempting to answer the Big Questions, but also for what can be known as true itself. After all, what question is more important than "isn't that the truth?"

2. "Trust Me"

No doubt you have heard someone say "trust me" to you before. But what does it really mean? The statement implies a number of things:

1. The person believes they have knowledge;
2. The person believes they have truth;
3. The person believes you have neither;
4. The person believes you might doubt them.

Note from the above example the word 'believes'. This word is there because unless the person is expressing a mathematical equation, it is unlikely they can fully prove their claim. That is because most statements are subjective - that is, dependent on the weltanschauung of the person listening. In fact, most of what you believe you know is likely because you trust the person or source.

Did You Know???

Take a moment and consider what you know about Pluto.  Make a dot-jot list of everything you know about the ex-planet (sorry Pluto fans).

In the list you generated, you may have said things like: a planet, made out of rock, in our solar system, has a moon, etc.

But it is safe to say your list probably didn't include: might exist. Why is that? 

The answer (probably) is that you learned about the planets in elementary school and you trusted the source - whether your teacher or textbook. You may have even seen a picture of it (like the one up there).

Well, unfortunately, much of what you 'know' is false! Pluto's status as a planet is, as you probably know, hotly debated, its composition is unknown, it enters and exits our solar system and has 3 moons. Plus, most of the images you see are only artist's impressions, not actual photos.  And besides, how many well-Photoshopped pictures have you seen that don't depict the truth?  In official circles Pluto is now considered a dwarf planet although having grown up with 9 planets I still cannot reconcile with this new fact - to me Pluto will always be a planet.

So what does this mean? That you must doubt everything you hear? Well, according to Hume - YES! But, for most of us the lesson here is to avoid unquestioning belief. That way you can have a healthy skepticism, rather than a paralyzing skepticism.

Oh, and by the way, if you also wrote down Pluto was the last planet in the solar system, well, have you heard of Eris?  Check out Eris:  Meet Eris, a newer member of our solar system!

3. Socratic Method

You have probably heard of the scientific method; it is the method scientists use to advance their hypotheses. Well, philosophy has a method too - the Socratic Method.

It has taken over 2000 years, but the lovers of the Socratic Dialogues are finally going to have a chance to expand their library. How? By purchasing the latest Socratic Dialogue written by... YOU!

Your task is to write a brand new Socratic dialogue. Using the Socratic Method, focus on answering the question: 'what is knowledge?' 

Here's is some information to help you along:

To assist you further examine the sample below from Plato's Republic:

* Note how he employs a series of questions. By doing so Socrates made the people who answered the questions understand not only the point he was trying to make but also that they didn't know as much as they thought and previously unknown truth was being revealed to them.

"And who is best able to do good to his friends and evil to his enemies in time of sickness?

The physician.

Or when they are on a voyage, amid the perils of the sea?

The pilot.

And in what sort of actions or with a view to what result is the just man most able to do harm to his enemy and good to his friend?

In going to war against the one and in making alliances with the other.

But when a man is well, my dear Polemarchus, there is no need of a physician?

No.

And he who is not on a voyage has no need of a pilot?

No.

Then in time of peace justice will be of no use?

I am very far from thinking so.

You think that justice may be of use in peace as well as in war?"

Note how Socrates proved his point by asking questions? The final question is arhetorical question. It is designed not to be answered. Socrates asked the question for the purpose of summing up his argument. There is only one answer the other person could give, when examining the argument Socrates presented, and it was Yes.

THE REPUBLIC by Plato (360 B.C.), translated by Benjamin Jowett. Public domain work found here.

General Rules for employing Socratic Dialogue:

1. Build from your own experience;
2. Do not be too emotional;
3. Keep your examples as clear and simple as possible;
4. Be interesting to everyone;
5. The question plays a central role in the example;
6. Do not involve the participant(s) directly (their mind(s) may draw upon an experience that is quite different than yours);
7. Do not speak hypothetically;
8. Express your doubts;
9. Strive for consensus.

Here's one I wrote:

Socrates:    What do you rely upon most to see what is going on around you?

Mark:          My eyes.

Socrates:    And do your eyes give you an accurate picture of the world.

Mark:          Yes, although they need a bit of help so I wear glasses.

Socrates:    Tell me what your eyes see in the sky at night, and sometimes in the day.

Mark:          The most noticeable thing is our beautiful Moon which rises in the east and travels             across the sky setting in the west.

Socrates:    And what does that tell you about the motion of the Moon?

Mark:          That the Moon is in orbit around the Earth.

Socrates:    Good!  And tell me what your eyes see in the sky during the day?

Mark:         The most noticeable thing is our blazing sun which rises in the east and travels across the sky setting in the west.

Socrates:    And what does that tell you about the motion of the Sun?

Mark:          That the Sun is in orbit around the Earth too, just like the Moon!

Modern Scientist:  Whoah!  Hold on a minute, fellas!!

DAY 38 Epistemology - What's Epistemology?

You all remember the "red pill blue pill" scene in The Matrix?  It's become a popular symbol for living in the bliss of ignorance (blue pill) vs. living in the stark reality of the truth (red pill).

In many ways it represents Epistemology quite well - Epistemology is the philosophy of the truth, or how we know what we know, or how we think we know what we know.  In short we will spend the next few weeks examining how people arrive at their own versions of the truth and it's more complex and interesting than you might think.

For example, these two definitions of "Theory" are in the Oxford English Dictionary:

Theory (1): A system of ideas or statements held as an explanation or account of a group of facts or phenomena; a hypothesis that has been confirmed or established by observation or experiment, and is accepted as accounting for the known facts; a statement of what are held to be the general law, principles or causes of something known or observed.

Theory (2): A hypothesis proposed as an explanation; hence, a mere hypothesis, speculation, conjecture; an idea or set of ideas about something; an individual view or notion.

Consider the old theory about the Earth being the center of the universe, that everything observable out there revolves around the Earth.  That fits nicely within Theory (1) above.  Of course we now know that the sun is what we revolve around, the sun goes around the Milky Way, etc. etc. - the current Heliocentric Theory of the Solar System (we go around the sun) also fits in nicely with Theory (1) above.  The thing is one of these scenarios is correct and one is not.  Both, however, rely heavily on things we can actually observe but because of perspective the actual meaning of those things changes drastically.

Now consider things like Evolution, Creationism, God, the loyalty of your friends, and the list goes on.  Where do they fit in to our understanding of what we "know" or think we "know"?  How can you be sure?  What evidence, if any, are you using in your thinking on the topic?

The answer to that last question goes a long way to explain how Epistemology, the philosophical study of knowledge, applies to you in your everyday life.

Now we'll have a look at this video and take notes on the most relevant parts dealing with Epistemology - the video covers some big topics.

This is streamed from the Halton Board's website - you can access it at any school computer without logging into the site but if you're at home you'll be prompted during your login to put in the long number on your Library Card (student ID card that you get from your school).  Don't use your student number it won't work - the other much longer number on your card is what you need.  Here's the link:

The Day the Universe Changed - Part 1 - if this doesn't work it's because you'll need to login.  In that case go to:

HDSB Online Library Site  (which is actually hdsb.ca/library/) and enter their Education Library Catalogue and search for "The Day the Universe Changed" - the video to watch is Part 1 - The Way We Are - It Started with the Greeks.
