3. In today’s society, we encounter a lot of information
• Media and our interactions with our friends,
family, and members of the community.
• Most of the information we receive is helpful,
but some may mislead us or may even be utterly
false.
• Every day we are confronted with news, claims
and announcements from our peers, family
members, figures of authority, the
government, and media.
• How do we know if they telling the truth?

4. In today’s society, we encounter a lot of information
• Philosophers often wrestle with the concept of
truth.
• Knowledge must be truthful to gain validity
and acceptance.
• For example, when we answer a “True or False”
test, we judge if the statements we read are
true or false. This means that statements may
have truth or may not have truth.
• Statements about the world or reality are
called “propositions” and these propositions
may or may not carry truth. Propositions are
usually stated as short statements or sentences.

KNOWLEDGE
The clear awareness and understanding of
something. It is the product of questions that
allow for clear answers provided by facts.
Our knowledge is comprised of ideas and
beliefs that we know to be true.
7. “
I know that...
I know why...
I know how...
One important aspect of knowledge- it is based on
reality. This simply means that what we know is
what is observable or evident in the real world.

Example: “I know that fish live in water.”

10. 3.
CLAIM
Statements that are not evidently or
immediately known to be true
They require further examination to
establish whether it is true or false.
11. “
Example:
“I know that my school is the best school in the
city.”
You may know that reading is a better activity than
playing basketball but the truth of your statement
will be contested by other people.

12. How do we know if something is TRUE?
■ Ancient Greek Philosophers approached the
problem of truth by looking at the nature
of knowledge and how we know what we
know.
■ We assume that everything we know about
this world is true. But philosophers who
pondered upon the origins of knowledge
doubted everything there is to know
about themselves and the world.
12
14. ■ As it drives our desire to discover truth. In
philosophy, systematic doubt is employed to
determine truth. This means that every
statement, claim, evidence, and is scrutinized
and analysed.
■ Nothing is taken as true unless there is
sufficient reason and evidence to prove that
is indeed true.
Doubt has very important purpose in philosophy

15. EXAMPLE:
■ Am I alive?
■ Do I have a body?
■ Can I breathe?

16. ■ Do you have a pulse? Can you feel your
heartbeat?
■ Do you have arms, legs and feet?
■ Try to take a deep breath, then exhale.
Were you ble to do it?
■ If your answer is “yes” then you can
conclude with certainty that.....
Now, Examine yourself
16
17. you can now say...
■ I am alive!
■ I have a body!
■ I can breathe!

18. 1.
A BELIEF is true if...
it can be justified or provE THROUGH
the use of one’s senses.

satements as fact?
19
20. ■ Filipino (noun):

29. EVIDENCE

falsified.
A person may be issued
with documents
but it may contain wrong information
or typographical error.

30. if your name is mispelled in your
birthcertificate
DOES YOUR IDENTITY CHANGE?

31. Example:
I can ride a bike/ Can I ride a
bike?
I can fry an egg/ Can I fry an egg?
31
32. ■ The obvious answer would be, is to
actually ride it cook it.--- BUT, some would
argue that the proof is not only in the act but
also in the product.
■ This means that you should not only show
that you can fry an egg but that also you can
make delicious fried eggs.
How will you prove that you can really cook an egg?

A BELIEF is true if...
a person can prove a statement through
an action.

54. FALLACY CHARACTERISTICS EXAMPLE
Fallacy of
Composition
Assuming that what is true
of a part is true for the
whole
Each brick in that building weighs less than
a pound. Therefore, the building weighs
less than a pound.
Hydrogen is not wet. Oxygen is not wet.

parts

you can do better in this course!

58. HOW CAN AN UNDERSTANDING OF THE
DIFFERNCE BETWEEN TRUTH AND
OPINION LEAD USTO WISDOM?
58
Understanding of opinions and facts and the
means to distinguish one from the other
can further improve our understanding and
appreciation of varied views and ideas. The
ability to determine truth goes hand in
hand with the holistic perspective and
enables us to make wiser decisions,
especially in choosing the ideas and views
which we find acceptable.
59. HOW CAN AN UNDERSTANDING OF THE
DIFFERNCE BETWEEN TRUTH AND
OPINION LEAD USTO WISDOM?
59
An individual cannot live his or her life just
agreeing with everybody he or she meets. A
critical mind aided by philosophy can help us form
our own personal point of view that can guide us
in making decisions and actions when faced with a
problem.
Philosophy can help us determine ideas that are
truthful and acceptable which we can then use
to form our own views regarding certain
matters.
60. Let us imagine several individuals reacting to a
news in television and radio about teh recent
killings of drug pushers and addicts throughout the
country
MANG ANTONIO ATTY. MACARAIG MRS. LOPEZ
FATHER GOMEZ MR. TOLENTINO MRS. ALONZO
60
61. NOW, LET'S LOOK AT THEIR BACKGROUND
MANG ANTONIO
A citizen who lives in a
barangay where the
presence of drugs addicts is
a problem
ATTY. MACARAIG
A lawyer and a citizen
MRS. LOPEZ
A housewife whose
family lives in a
community
FATHER GOMEZ
A priest
MR. TOLENTINO
A father whose daughter
was raped and murdered
by drug addicts.
MRS. ALONZO
A mother whose son is
a drug addict.

62. Figuring out the backgrounds of the people who
made the statements allows us to undertand the
context by which they formed their views and
opinions on the issue.
65. Which among the opinions is most similar to your
own personal bias regarding the issue of the drug
addicts?
66. PHILOSOPHY CAN HELP US EXAMINE VARIOUS VIEWS
ON RELEVANT ISSUES AND OUR LIVES. AN OBJECTIVE
EVALUATION OF OPINIONS AND AN AWARENESS OF
OUR OWN PERSONAL BIASES CAN HELP US MAKE WISE
CHOICES RAGRDING THE MOST ACCEPTABLE VIEWS TO
ADOPT AND THE RIGHT ACTIONS TO UNDERTAKE.
