The Theory of Knowledge 
Epistemology as a branch of philosophy that 
investigates the origin, nature and methods 
and limits of human knowledge cannot be 
overemphasized. 
Philosophers are concerned with 
determining the basis of all knowledge and 
to agree upon standards and criteria for 
judging the veracity of such claims.
The Theories of Knowledge 
A theory is a coherent group of general 
prepositions used as principles of 
explanation for a class of phenomena. It is a 
branch of a science or an art that deals with 
its principles and methods and put forth as a 
possible explanation of certain relations and 
serves as a basis of argument or 
experimentation by which the truth is 
established.
The Theories of Knowledge 
1. The Objective Theory 
This theory asserts that there is a world 
outside of ourselves which exists. This outer 
world has qualities of its own. These qualities are 
not determined by the various sense organs or 
the mental condition and analytical capability 
of the perceiver. These are the physical objects 
outside of or beyond ourselves which are lent 
to the perceiver.
The Theories of Knowledge 
1. The Objective Theory 
John Locke refers to this as “Copy Theory” 
or “Representative Realism”
The Theories of Knowledge 
1. The Objective Theory 
There are two pieces of evidence that are 
cited as references of the objective theory in 
relation to the theory of knowledge: 1) Sense 
Experience; 2) Reflection. These are 
characterized by our awareness of something 
which may not be outside of or our beyond 
ourselves.
The Theories of Knowledge 
1. The Objective Theory 
Sometimes we are not even aware that 
something in our minds exists. What exists is 
either sensible or intelligible; and thus 
knowledge is the knowledge and sensation is 
the sensible. 
Two kinds of knowing: 1) Perceptual Knowing 
– concerned with the sensing of particular 
things, and 2) Conceptual Knowing – 
concerned with the recognition of universal 
identities
The Theories of Knowledge 
1. The Objective Theory 
Sensation is always true, though what 
imagination creates may often be false. 
Because sensations are always true, knowledge 
based on true sensation is always true as well. It 
is through the repetition of individual sensation 
that the knowledge of the universal emerges in 
thinking.
The Theories of Knowledge 
2. Conception Theory 
The knowing of universal forms which are 
expressed in class concept of plant, birds, and 
human beings, begins with sensation but is 
completed in the intellect by way of memory 
which enables the knower to identify that 
which is the same in varied experiences.
The Theories of Knowledge 
2. Conception Theory 
According to Aristotle, repeated memories 
of the same thing give rise to experience; 
because the memories, though numerically 
many, constitute a single experience”. 
Experience that is universal when established as 
a whole in the soul – the one that corresponds 
to the many, the unity that is identifiably 
present in them.
The Theories of Knowledge 
2. Conception Theory 
It is that universal manifested in the form of 
the particular that enables us to recognize 
what we are sensing. Particulars are objects 
and their attributes get their identities by the 
way of the definitions of the universals for the 
individual’s change and come and go while 
essences are potentially in the intellect and 
become actual experience.
The Theories of Knowledge 
2. Conception Theory 
Human Beings possess two intellects: 1) 
Passive, records particular sensations; 2) Active, 
identifies the universal in particular sensation. 
The passive intellectual becomes all things and 
the active intellect makes all things.
The Theories of Knowledge 
2. Conception Theory 
The passive intellect is related to sense 
perception and perishes as a body and sense 
perish. 
Aristotle analyzes two kinds of certain 
knowledge: 1) scientific knowledge which 
provides facts; 2) intuitive apprehension which 
scientific knowledge of facts and particulars 
occurs.
The Theories of Knowledge 
Other source of Knowledge 
Custom – is a group pattern of habitual activity 
usually transmitted from one generation to 
another. It is a habitual practice and the usual 
way of acting in a given circumstances of a 
certain environment. 
Traditions – is the handling down of statement, 
beliefs, legends, and custom from generation 
to generation especially by words of mouth or 
by practice.
The Theories of Knowledge 
Other source of Knowledge 
Sense Perception – This is inherent capacity of 
any of the faculties, as sight, hearing smell, 
taste, or touch by which man perceive stimuli 
from outside and inside the body. 
Intuition – This is a direct perception of fact and 
truth, which is independent of any reasoning 
process and considered one possible source of 
knowledge
The Theories of Knowledge 
Other source of Knowledge 
Intuition – According to Carl Jung, a 
psychologist, this is “thinking which is done on 
the level of unconsciousness”. On the other 
hand, Henri Bergson, renowned French 
Philosopher, referred to intuition as a “dynamic 
process of thought which penetrated the static 
limitation of logic”.
The Theories of Knowledge 
Other source of Knowledge 
Authority – Testimonies by individuals who are 
considered authorities in their specialized fields 
and verified facts from exceptional and 
extraordinary fields of various sciences found and 
attested by qualifies bodies are sources or our 
knowledge. 
Reason – faculty or power acquiring intellectual 
knowledge, wither by direct understanding of first 
principles or by argument to form conclusion, 
judgments or inferences from facts and premises.
The Problem of Knowledge 
Philosophers have been concerned with finding out 
if we can really “know” anything in the sense of 
possessing information that is open to questions. 
The SOPHISTS, these class of wise men were 
extremely doubtful about the possibility of 
discovering anything that was really true. The two 
leading Sophists – Portagoras and Gorgias, to them 
man should no bother to seek what he can never 
find, instead, everyone should measure matters 
according to his nature and needs, inasmuch as 
man alone was the measure of all things. Man 
should accept the fact that all his alleged 
knowledge was only relative to man’s outlook.
The Problem of Knowledge 
To Socrates, we do not learn anything – we 
remember that we already know all the knowledge 
of forms or universal already in our mind. 
Kinds of Knowledge according to Socrates: 
Visible and Intelligible 
Opinions 
Shadow
The Problem of Knowledge 
The only judgments we were forced to make are 
those regarding clear and distinct ideas. We are 
compelled to assert to any clear and distinct ideas 
and to believe that whatever is clear and distinct 
ideas is true.
Barriers in Attaining Knowledge 
1. Blind adherence to Authority. This is what referred 
to as authoritarianism – a belief that knowledge is 
acquired and validated by way of complete 
subjection to authority, devoid of effort to find out 
what is true or false. 
2. Propaganda. This is a deliberate and methodical 
strategy of spreading unfounded and misleading 
information or ideas to influence and control the 
minds of the followers to adhere to a certain 
belief or ideology of a particular movement or 
organization.
Barriers in Attaining Knowledge 
3. Prejudice. This is an unfavorable opinion or feeling 
without justifiable grounds or adequate 
knowledge or information on the issue or subject. 
An individual with prejudice is emotionally 
charged. He thinks and reasons resulting from 
some judgment and action according to his self – 
interest. 
4. Fallacies in reasoning. A fallacy is any sort od 
mistake in reasoning or inference. It is a deceptive 
arguments that seems conclusive and valid but 
actually false. (Ambiguity: Major source)
Barriers in Attaining Knowledge 
Contextual Fallacies. Do not depend on 
grammatical misuses of language, or upon formal 
mistakes in reasoning. They depend on context in 
which the utterance is made. 
Linguistic Fallacies. Based on the structure and 
consistency of an arguments, examples of which are 
those dealing with play on words. 
Material Fallacies. Errors are based on the 
content of the argument that is apparently faulty 
with misleading evidence or an appeal to feeling 
instead of reason based on logic.
