We explain what epistemology is, what it studies and the functions it fulfills. Also, what are their characteristics, types and examples.

What is epistemology?

Epistemology is the branch of philosophy interested in the study of knowledge , that is, it is the theory of knowledge . Its name comes from the Greek words epist?m? ("knowledge") and lógos ("study"). That which has to do with the processes of obtaining or formulating knowledge is called epistemological.

Epistemology addresses problems of various kinds about the way in which we understand knowledge, the way in which we acquire and validate it . It always seeks to answer the question about what is possible to get to know and through what means or mechanisms.

In that search, epistemology can cross or combine its field of study with that of many other disciplines. In addition, it can serve as a basis for them to think about themselves.

Concept of epistemology

Concept of epistemology

Epistemology is one of the four great traditional branches of philosophy , along with metaphysics, logic and ethics .

It is a discipline that studies human knowledge and its capacity for reasoning to understand precisely how said knowledge and said capacity operate, that is, how it is possible that knowledge exists.

Practically all the great philosophers of history have contributed to it in one way or another, proposing concepts and various mechanisms for the validation of knowledge.

History of epistemology

Schools of epistemology

The history of epistemology is long and begins along with philosophy, in Ancient Greece (1200 BC - 146 BC) , especially with the works of the Perménides philosophers (5th century BC). and Plato (4th century BC).

At that time, a distinction was made between two types of knowledge : doxa or vulgar knowledge, lacking critical accompaniment; and the episteme , the reflective knowledge fruit of the rigor of thought . However, there was no equivalent discipline to modern epistemology.

This branch of philosophy took its first formal steps in the European Renaissance (15th-16th centuries) . This was due to the emergence of human reason as a method of understanding the world, replacing medieval faith .

Its impetus is largely due to the works of philosophers and scientists such as Johannes Kepler (1571-1631) , Galileo Galilei (1564-1642), Francis Bacon (1561-1626), René Descartes (1596-1650), Isaac Newton ( 1642-1727), John Locke (1632-1704), Gottfried Leibniz (1646-1717) and Immanuel Kant (1724-1804).

Later, epistemology was key in the formulation of the concept of science and scientific knowledge , which prevailed in the thought of the 19th and 20th centuries.

Schools of epistemology

Critical rationalism is the fruit of the work of Karl Popper. 

Starting in the 20th century , three different schools of contemporary epistemology were founded, still in force today, and which are:

  • The logical neopositivism. As a result of the studies of Bertrand Russel (1872-1970) and Ludwig Wittgenstein (1889-1951), it was formed around the Vienna Circle, which turned the positivism inherited from the 19th century into a doctrine that later found an echo in the Berlin Circle and the Prague Circle.
  • Critical rationalism. Fruit of the work of Karl Popper (1902-1994), who stood up critically against logical neopositivism, contributing a decisive turn to the foundations of the Vienna Circle.
  • Postpopperianism. Philosophers fall into this category who, although they are inspired by positivism or by Popper's work, are not entirely part of it.

Object of study of spistemology

As we have said, epistemology focuses on the nature, origin, and limits of human knowledge . The latter is understood as the point of intersection between human beliefs and truths acquired in one way or another.

Epistemology then determines the types of possible knowledge , the mechanisms by which we can form them, and the logic that allows us to determine whether it is valid knowledge or not.

In this sense, its four most common concepts are truth, objectivity, reality, and justification.

Epistemology problems

Epistemology problems

Epistemology addresses general problems of knowledge and specific to the field of different sciences or disciplines. They can be summarized as follows, starting from the most general to the most specific:

  • Problems about the relationships between the various fields of scientific knowledge, how the sciences are classified, what points of contact they have, etc.
  • Problems about formal and concrete sciences.
  • Problems about the conceptual loan between the sciences and how the change of perspective between them also modifies the meaning given to certain "common" ideas .
  • Problems related to the theoretical and experimental aspects of science, that is, around the verification, objectivity, scientific truth and the formulation of laws, theories and hypotheses.
  • Problems inherent to formal thought: logical and mathematical , the limits between them and their ontology.
  • Problems inherent to the sciences of reality: everything related to experimental verification, scientific methodology and inductive processes.
  • Problems inherent to the life and human sciences , in which the need to distinguish between facts and realities, evaluations and interpretations arises.

Functions of epistemology

Some of the functions of this discipline in the field of study and research have to do with:

  • The limits of knowledge. You can review and question the accepted methods of formulating knowledge from the real world.
  • The methodologies. Epistemology is concerned with putting into judgment the methods we use to distinguish valid knowledge from a belief or assumption, or to distinguish knowledge according to where it comes from.
  • The epistemic currents. This discipline contributes enormously to the eternal debate regarding how ideas are built and how human beings create knowledge.

Differences with gnoseology

Differences with gnoseology

Some authors affirm that gnoseology and epistemology are not the same. The fundamental difference between them would have to do with the fact that epistemology is in charge of studying the scope of all kinds of knowledge in general , while epistemology is limited to scientific knowledge.

However, this distinction today is questioned and many scholars accept epistemology as more or less synonymous with epistemology, or as an even broader category that we would call theory of knowledge .

Importance of epistemology

Epistemology is key in understanding how the sciences operate , which in today's world are perhaps the greatest force of theoretical and applied knowledge available to human beings.

In this sense, epistemological knowledge is at the heart of contemporary philosophy , allowing us to know the way we think about knowledge itself. This search results in innovation , scientific questioning and new methodologies to understand the universe .

Types of knowledge

Types of knowledge

Depending on the epistemological point of view, it will be possible to distinguish between different types of knowledge, for example:

  • Radical point of view. There are no types of knowledge.
  • Empiricist or logical positivist point of view.  There are two types of knowledge, which are analytical (a priori) and synthetic (a posteriori).
  • Kantian point of view.  There are three types of knowledge, which are the analytical a priori, the synthetic a posteriori and the synthetic a priori.

Examples of epistemology

A very obvious example of the use of epistemology is the differentiation of scientific, official, proven and accepted knowledge from pseudoscientific. In this way, epistemology proposes models of distinction, judgment and analysis of knowledge , which allow us to differentiate a belief, a personal deduction and a scientific truth.
