Epistemology is the branch of philosophy that investigates the origin, nature, methods and limits of human knowledge. It seeks to understand what knowledge is, how it is acquired, and what can be known. There are different theories about the nature of knowledge, including empiricism which believes knowledge comes from sensory experience, rationalism which believes knowledge comes from reason, and idealism which believes reality is associated with ideas rather than material objects. Skepticism also questions the extent and limitations of human knowledge. Epistemologists explore questions around whether knowledge is possible and what types of knowledge exist.

5.  What is knowledge ?
 Knowledge is justified as true belief .
 It means that :
 The person must be able to justify the claim .
 The claim itself must be true .
 The person must belief in it.

6.  Knowledge as justified true belief :

 It must be possiable to justify that claim .
 It must also be a fact that people have indeed
been to the moon .
 And finally the person must also actually believe
that people have walked on the moon .

7.  How is knowledge aquired ?
 There are different sources to record the truth .
 God (Allah )Religion (spiritual source) Qurain
sunnah.
 Philosophers (critical thinking )
 Knowledge can be earn by mingling with society
by keen observation and questioning attitude and
clearing the self opinion on each matter whether
affect us or not by refering and filtering the
various opinions of others.

come from reason. Thus humans have the ability
to reason and there for they have the power to

tends to blur the line between belief and
knowledge since there are many religion .

10.  There are some major branches of epistemology have
developed over a period of time .
 Empiricism
 Rationalism
 Idealism
 Skipticism.
Empiricism:
 In philosophy empiricism is a theory that states that
knowledge comes only or primarily from sensory
experience .

11.  Empiricism emphasizes the role of empirical evidance
in the formation of ideas ,rather than innate ideas or
tradition .However empiricists may argue that
traditions arise due to relations of previous sense
experiences .
 Historically empiricism was associated with the “blank
slate” concept according to which the human mind is
blank at birth and develop s its thoughts only through
experience.

12.  Rationalism:
In philosophy rationalism is the epistemological view
that regards reason as the chief source and test of
knowledge or any view appealing to reason as a source
of knowledge or justification .
More formally rationalism is defined as a
methodology or a theory in which the criterion(judged
or decided) of the truth is not sensory but intellectual
and deductive.

13.  Idealism :
 Idealism is the metaphysical view that
associates reality to ideas in the mind rather than to
material objects. It lays emphasis on the mental or
spiritual components of experience, and renounces
the notion of material existence.
 According to this approach an idea emerged and then
tested physically will be the real knowledge.

14.  Skipticism:
 It is generally a questioning attitude or doubts to words
knowledge claims .
 Skeptic means one is in doubt .
 They are the philosophers who doubt the finality of
knowledge .
 Knowledge is always have certain limitations. We can't
take the 100% exact decision based on our knowledge.
