Methods of
Philosophizing:
Distinguishing
Opinion from Truth

Determine which one states fact or opinion.

How did you determine that each statement is
considered truth or opinion?

How do you determine the truth?

Do you value “truth”?
How should we put value on “truth” in
philosophizing?

Cite an instance in your life where you find truth
to be essential/significant.

How are we to determine
the truthfulness of a
situation or a statement?

1.
A BELIEF is true if...
it can be justified or provE THROUGH
the use of one’ssenses.
37

EXAMPLE:
■ I am a Filipino.
Can we use our senses to prove this
satements as fact?
38

■ Filipino (noun):
-A native of the Philipine Island.
-A citizen of the Reublic of the
Philippines
39
We can look at a dictionary

2.
it is based on facts.

Are you now convinced
that you are a filipino?
If not....
41

&
Askyour
parentsor
other
relatives.
Lookfor
official
documents
thatprove
youarea
Filipino.
42
We can try the following...

When all of your family members
answered “Yes!”...
Then you are a Filipino.
👪
43

3.
you Get a consensus and people agree on
a common belief.
44

BUT
45
this approach has certain limitations.
Getting everyone agree on
something
may not make that belief true.

4.
there are official documents/ supporting
facts.
46

Birth certificate
shows factual
information
regarding your
birth.
Since it is
issued by an
istitution that
the documens
are truthful.
BUT,
this also
has a
47
limitation
Looking at official documents

EVIDENCE
48
especially documents can be forged or
falsified.
A person may be issued
with documents
but it may contain wrong information
or typographical error.

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

Example:
 I can ride a bike/ Can I ride a
bike?
 I can fry an egg/ Can I fry an egg?
50

■ 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.
51
How will you prove that you can really cook an egg?

5.
a person can prove a statement through
an action.
52

6.
philosophers argue that a bELIEF is true if...
it is subjected to tests to determine the
truth

only give facts but also provide
conclusions or perspectives regarding
certain situations.
 They may advance a belief about
certain things or provide
explanations.
 The bases for making arguments
and convincing people that a
certain claim is a fact. They are
often influenced by bias.

CONCLUSION
 Judgement based on certain facts.

Beliefs
 Statements that express convictions that are not
easily and clearly explained by facts.
 T
o judge the truthfulness of a belief, we must also
consider things such as the person’s experiences
and views.

Beliefs
 Example: “I believe that God put me on this Earth
to spread his message of love.”

Explanation
 Statements that assume the claim to be true and
provide reasons why the statement is true.
 Example: Statement 4: My sister is selfish

Arguments
 Series of statements that provide reasons to convince
the reader or listener that a claim or opinion is
truthful.
 They often take the form of statements that are
either claims of facts and are phrased in such a way
that they seem reasonable.

of the conversation, how will
you react to the statements?

HOW CAN AN UNDERSTANDING OF THE
DIFFERNCE BETWEENTRUTHAND
OPINION LEAD USTO WISDOM?
 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.
76

HOW CAN AN UNDERSTANDING OF THE
DIFFERNCE BETWEENTRUTHAND
OPINION LEAD USTO WISDOM?
77
 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.

Let us imagine several individuals reacting to a
news in television and radio about the recent
killings of drug pushers and addicts throughout the
country
MANGANTONIO ATTY.MACARAIG MRS.LOPEZ
FATHERGOMEZ MR.TOLENTINO MRS.ALONZO
78

NOW, LET'S LOOK AT THEIR BACKGROUND
MANGANTONIO
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
FATHERGOMEZ
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.

 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.

THEIR VIEWS REGARDING DRUG
ADDICTS
81

THEIR VIEWS ON THE KILLING OF THE DRUG
ADDICTS
83

Which among the opinions is most similar to your
own personal bias regarding the issue of the drug
addicts?

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.
87

How will you determine the truth from an opinion?

How do we evaluate truth from opinions in
different situations?

How does it work?
