Chapter 1 – Theory of Knowledge
Chapter OverviewChapter Overview The world is a
confusing place.
People carry many different opinions.
The world we live in a much bigger then the “world” each of us live in on a daily basis.
3 Possible Solutions to 3 Possible Solutions to the Problem of the Problem of
Knowledge…Knowledge… Common Sense
Certainty
Relativism
Common SenseCommon Sense Our “common sense” probably
contains inaccuracies and biases that we are not aware of.
Common sense” consists of beliefs that can be based on prejudice, hearsay and blind appeals.
Hearsay: unverified, unofficial information gained or acquired from another and not part of one’s direct knowledge. (Examples: gossip or rumors)
Mental MapMental Map Mental Map: our ideas of what is
true and what is false, what is reasonable and what is unreasonable, what is right and what is wrong, etc… Our mental maps may give
us a distorted picture of reality
Our ideas and beliefs come from many sources… our own experience, parents, friends, teachers, books and the media… It is possible that there are inaccuracies in some of this knowledge, since we don’t always have the chance to check up on some information.
Paradox of Paradox of CartographyCartography
Paradox of cartography: there is no such thing as a “perfect map”. A perfect map would be useless, because it would be life-sized.
CertaintyCertainty It has often been thought that
certainty is what distinguishes knowledge from mere belief.
Certainty: The idea here is that when you know something you are certain that it is true and have no doubts about it; but when you merely believe it, you may think it is true, but you are not certain.
Ways of KnowingWays of Knowing Language
Perception
Reason
Emotion
* We acquire knowledge about the world through language, perception, reason and emotion, but none of these ways of knowing can give us certainty.
Radical DoubtRadical Doubt
Do we truly Exist???
RelativismRelativism there is no such thing as absolute truth that
exists in an objective way independent of what anyone happens to believe is true.
truth is relative (truth may be different for different individuals or for different cultures)
* According to relativism, truth is relative to the individual; but the fact that we take seriously the idea that someone may be wrong in their beliefs suggests that relativism is false.
Belief vs. TruthBelief vs. Truth The fact that you “believe”
something is true, does not mean that it is actually true. (Santa Claus Example)
JudgementJudgement since we live in a world with few
black and white certainties, we must rely more on judgement than proof in deciding what to believe.
It is important to find a balance between being skeptical and open-minded.
Reasonable Reasonable KnowledgeKnowledge
2 preliminary criteria to use to determine whether or not a knowledge claim is reasonable
Evidence for a belief to be reasonable there should
be some positive evidence in support of it Coherence
deciding whether or not a belief coheres, or fits in, with our current understanding of things
we must examine our doubts of a belief one at a time
always demand good evidence before believing something
argument ad argument ad ignorantiamignorantiam
a fallacy that explains, the fact that you can’t prove that something isn’t true does nothing to show that it is true.
Confirmation BiasConfirmation Bias to notice only evidence that supports
our beliefs
we should look for evidence in favor of our beliefs as well as evidence that counts against our beliefs (EX: horoscope)
Who Cares???Who Cares??? Do people have the
right to believe what they want to believe?
Are some beliefs more worthy of respect than others?
Why do our beliefs Why do our beliefs matter?matter?
ConclusionConclusion 3 possible solutions to the problem of
knowledge common sense certainty relativism
none of these are entirely adequate
Since the problem of knowledge has no easy solution we must use our judgement in trying to decide what to believe.
