What is Epistemology?

The theory of knowledge is known as Epistemology. In the sense of scientific knowledge, epistemology is the theory of nature, origin and limitations of knowledge and is related to the mind's connection to reality.

Traditional epistemology is a branch of philosophy that studies the nature of knowledge. It looks at how we acquire and justify our beliefs about reality and the world around us. It investigates questions related to truth, justification, understanding, certainty and the relationship between experience and knowledge.

Epistemology contrasts with other major philosophical branches like metaphysics (the study of what is real), ethics (the study of right and wrong), aesthetics (the study of beauty) and logic (the study of valid arguments). Specifically to epistemology, rationalism contends that the nature of knowledge originates from a source of knowledge or rational thought rather than from the exterior world. At the same time, empiricism highlights the human ability to understand reality through the senses.

Epistemologists are the experts in the analysis of knowledge; most do not concentrate on knowledge acquaintance or procedural knowledge. They preferably focus on propositional knowledge in philosophy.

The forms of knowledge that epistemologists typically analyze include justified true belief, a priori knowledge, and empirical knowledge. Justified true belief states that the acquisition of knowledge is based on both justification and truth. A priori knowledge refers to information gleaned from logic or rational thinking, and finally empirical knowledge is acquired through sensory experience or observation.

Propositional knowledge includes different forms of learning, such as human, scientific, perceptual, or any other kind of characterization of knowledge and beliefs. One objective of epistemology is to carry out analysis of knowledge or define the source of knowledge so that people may know what will or will not be known. Hence, the study of traditional epistemology or analysis of knowledge includes the meta-epistemology study (what people may know about learning).

There are various types of epistemology, but epistemology can be divided into two schools of thought: rationalism and empiricism. Most philosophers who studied analysis of knowledge supported any of these two schools of thought.

Since rationalism contends that the nature of knowledge originates from a source of knowledge or rational thought rather than from the exterior world, empiricism highlights the human ability to understand reality through the senses.

Plato's Contribution to the Epistemology

Republic and Phaedo are the most famous texts of Plato in which he discussed Plato's theory of knowledge. Plato was one of the earliest philosophers to talk about what was later known as epistemology. Plato considered epistemology as a way to understand what the world is and how individuals relate to this world.

Plato had suspicions concerning humans' talent to gain knowledge of the natural world using their senses, thinking that the physical world was just a representation of the Realm, another realm referred to as the Realm of Forms.

For him, Forms were the absolute, constant, and perfect interpretations of objects and ideas. His well-known 'Allegory of the cave' explains how this contradiction between the two realms operates and how it adds to human knowledge. For example, if a person draws a triangle in the Realmysical Realm, it will be just a presentation of the Form of the Triangle.

Aristotle's work in the Epistemology

Aristotle did not consider epistemology as one of the most significant branches of philosophy. He became famous for his theories of aesthetics and ethics. Nevertheless, Aristotle added to Plato's definition of knowledge and analysis of the nature of knowledge with a particular focus on rhetoric and logic.

Plato codified various types of reasoning and illustrated how rhetoric might be used to make practical solutions. This technique was the foundation for many philosophers who wanted to investigate epistemology using a theologically consistent methodology.

Rene Descartes work on Epistemology

Descartes is also known as father of Modern Philosophy and according to Rene Descartes' definition of knowledge, one may obtain accurate human understanding only through the systematic application of reasoning, not from reading books.

He developed a method of systematic reasoning that is still used today in logic and science. Descartes was also an advocate for developing scientific truth through logic and skeptical inquiry rather than through reading books or relying solely on one's senses.

René Descartes is famous for his significant contributions to epistemology and, particularly, to rationalism. Unlike Aristotle and Plato, Rene Descartes's sceptical arguments started by questioning every aspect of reality to check if anything would remain indisputable when he said so.

René Descartes concluded that there is only one reality, i.e. human existence, commonly producing the phrase ''I think. Therefore I am.'' Considering that his sensory experiences might always be doubtful, René Descartes constructed his epistemological outline from the view that Rene Descartes cannot doubt his existence. Due to this belief in a benevolent God, he might have faith in his talent to have logical thought.

Kant's Contribution to the Epistemology

Immanuel Kant proposed the most challenging definition of knowledge and views on epistemology in philosophical history. In a way, Kant recalls early epistemology by Plato.

Kant believed that when individuals think about the world, they only consider the looks of things instead of considering what they are in real life. Kant claimed that time, space, colour, and the other factors of existence that many people seem to ignore are the aspects that people prefer in reality to make it easier to understand.

According to Kant's epistemology, fact is produced by and stays inside individuals who perceive reality rather than being an unchanging and external truth.

John Locke's work in Epistemology

John Locke believes that all knowledge is derived exclusively from experience. John Locke argues that the mind at the time of birth is a blank slate that people fill with their ideas after gaining experience from the world using their five senses.

Since the beginning of the 20th century, many philosophers declined the idea that knowledge involves a cognitive process.

For most Contemporary Philosophers modern epistemology has been reviewed to the degree where modern epistemology has been narrowed down to 3 essential criteria that must be fulfilled to ensure that fundamental beliefs can be viewed as the nature of knowledge in philosophy. These criteria include the following:

Belief: People cannot be asked to understand something if they do not know the source of knowledge or if they do not think it is accurate.

Truth: If a person believes something as a false belief, then they are unaware that it is a fact; they are making a mistake.

Justification: People should have acceptable justification for the things they believe for their belief to be factual human knowledge and learning.

It is a relatively new addition to the philosophy that deals with analysing the relevance of communities to knowledge. Modern philosophy social epistemologists identify that social epistemology is closely associated with the sociology of knowledge.

However, some contemporary philosophers view this relation differently. Some argue that the sociology of knowledge is an empirical enterprise and purely descriptive, whereas social epistemology is solely conceptual and, at a minimum, to some extent, a normative task. Other contemporary philosophy social epistemologists consider the two areas as indivisible.

Naturalized philosophy

Naturalized philosophy is a concept of knowledge and a component of a general programme of naturalism. Naturalists dismiss all shapes of supernaturalism, stating that reality (including culture and human life) is exhausted by what lies in the causal order of nature.

Naturalistic epistemology is a theory of knowledge approach based on using empirical data and scientific methods rather than depending entirely on the analysis of concepts and deductive methods. Human knowledge in philosophy is mainly related to justified true beliefs.

Feminist epistemologies construct a category of social epistemologies that assesses the association between institutions, social relations and understanding. Feminist epistemologies disregarded the existence of one truth per se and concentrated on whose knowledge is being revealed. In current times, feminist epistemologies have attracted a variety of fields, such as health, science and education.

In Greek, 'episteme' means words for knowledge. Epistemic justification represents the correct position of a person's beliefs in terms of knowledge, despite the disagreement in what it implies precisely. Some contend that right standing indicates potentially true beliefs.

True belief is one of the core concepts in epistemology. An idea is a behaviour someone holds about anything he considers the truth. According to Plato's epistemology, justified true belief is knowledge. Hence, an opinion demonstrates empirical knowledge, and justified beliefs are turned out to be true.

Forms of Knowledge

Following are different forms of knowledge that combine together to allow people to learn new concepts and exchange information.

Posteriori Knowledge

A posteriori knowledge is a form of knowledge which is achieved from personal experience. A posteriori knowledge gives people knowledge of their strengths and weaknesses.

Perceptual knowledge

Perceptual knowledge is related to how things appear. Perceptual knowledge is gained from the way things sound, look, smell, feel, or taste.

Foundational knowledge

Foundational knowledge involves skills, methods, principles, theories and facts. Foundational knowledge is crucial to independent or more advanced learning in an educational discipline.

Knowledge by acquaintance

Acquaintance knowledge or knowledge by acquaintance is gained when people know something, in absence of any inference. Example of acquaintance knowledge is to know the hardness or color of a table.

Epistemology is one of the most popular branches of philosophy. It deals with the theory of knowledge and how humans can gain an empirical understanding of reality, i.e. how they know what they know.

Epistemology is a significant educational discipline that connects not only with philosophy but also to subjects like quantum mechanics, historiography, cognitive process and cognitive science.
