What Is Knowledge Based on Epistemology?


Diego Sanchez

Epistemology is a branch of philosophy that deals with the nature of knowledge, belief, and justification. It seeks to understand the nature and limits of knowledge and how we acquire it. In this article, we will explore what knowledge is based on epistemology.

What is Knowledge?

Knowledge can be defined as justified true belief. This means that in order for something to be considered knowledge, it must be true, believed by the knower, and have a good reason for being believed. Let’s break this down further:

True: Knowledge must correspond to reality. It cannot be based on falsehoods or errors.

Believed: The knower must believe that the proposition is true. Simply knowing something without believing it does not constitute knowledge. – Justified: There must be good reasons or evidence for believing the proposition.

Theories of Knowledge

There are many theories of knowledge in epistemology. Three of the most prominent are:


Empiricism holds that all knowledge comes from experience. This means that we acquire knowledge through our senses (sight, sound, touch, taste, and smell) and through observation and experimentation. Empiricists believe that there are no innate ideas or concepts – everything we know comes from our experiences.


Rationalism holds that some knowledge can be acquired independently of experience. Rationalists believe that there are innate ideas or concepts – things we know without having to learn them through experience. For example, some rationalists believe that mathematical truths (such as 2+2=4) are known independently of experience.


Skepticism holds that we cannot have certain knowledge about anything. Skeptics argue that our beliefs are always subject to doubt and that we can never be completely certain about anything. Some skeptics take this to an extreme, arguing that we cannot even be certain of our own existence.

Types of Knowledge

There are many types of knowledge, including:

Procedural knowledge

Procedural knowledge is knowledge about how to do something. This type of knowledge is often acquired through practice and experience, such as learning how to ride a bike or play an instrument.

Declarative knowledge

Declarative knowledge is knowledge about facts and concepts. This type of knowledge can be acquired through reading, listening, and other forms of learning.

Tacit knowledge

Tacit knowledge is knowledge that is difficult to articulate or transfer to others. This type of knowledge is often acquired through experience and practice, such as knowing how to ride a bike without being able to explain exactly how you do it.


In conclusion, epistemology seeks to understand the nature and limits of knowledge. Knowledge can be defined as justified true belief and there are many theories of how we acquire it.

There are also many types of knowledge, including procedural, declarative, and tacit. By studying epistemology, we can gain a deeper understanding of what we know and how we know it.
