This article provides an introduction to the concept of positivism and explains the August Comte’s theory of positivism.

Positivism is a philosophical approach which suggests that reliable and authentic knowledge can only be acquired through the application of the scientific method, including experimentation, measurement, observation, testing, and verification.

Positivism emerged as a scientific approach in the 19th century and challenged the traditional style of acquiring of knowledge, which was primarily based on speculation, imagination, and guesswork rather than the scientific method.
The main assumptions of positivism are as follows:

1. Knowledge that is derived only through the scientific method is reliable and can be called positive knowledge. The term positive knowledge simply means scientific knowledge, and this is why this ideology is called positivism.
2. Positivism advocates the use of scientific methods (e.g., experiments, measurements, observation, testing, and verification) to generate positive or scientific knowledge, which is scientifically testable and verifiable.
3. This approach challenges the traditional style of building knowledge based on speculation, imagination, and guesswork because the knowledge generated in that way is not reliable and cannot be called positive or scientific knowledge.

Auguste Comte (1788–1857), a French sociologist, is widely recognized as the founder of positivism. He was the first thinker who presented the principles of positivism to establish criteria for the development of scientific knowledge. The core assumptions of positivism (as described above) are largely derived from the following works of Comte, in which he emphasized the application of the scientific method for acquiring valid and reliable knowledge.

Comte’s theory of positivism is primarily presented in his two major works:

1. The Course of Positive Philosophy (published in six volumes between 1830 and 1842).
2. A General View of Positivism (published in 1848).

In the first three volumes of The Course of Positive Philosophy, Comte examined the physical sciences, including physics, chemistry, mathematics, biology, and astronomy. The latter three volumes focus on the emerging social sciences, particularly sociology. Across these works, Comte consistently emphasized the importance of applying scientific methods to all fields of knowledge. In A General View of Positivism, he further elaborated on the nature of the scientific method as a systematic approach to generating knowledge that is universally valid and empirically verifiable.

Auguste Comte is also regarded as the father of sociology. He introduced the term “sociology” in 1838, at a time when the study of society was not recognized as an independent discipline but rather as a branch of general philosophy. Comte played a foundational role in establishing sociology as a distinct scientific field.

Comte believed that positivism is essential for all branches of knowledge, including both natural and social sciences. However, his primary objective was to establish sociology as a scientific discipline. Therefore, he emphasized the application of principles of positivism to sociology (the study of society) with the aim of securing its recognition as a science comparable to established disciplines such as physics and chemistry. In pursuit of this objective, Comte defined sociology as the scientific study of human society, focusing on its structure and functions. He argued that the study of society must be based on scientific methods in order to produce knowledge that contributes to social progress and development. It means that  sociological inquiry should be based on empirical evidence rather than speculation which had previously dominated philosophical thought.

The key aspects of Comte’s positivism in relation to sociology are as follows:

1. Sociology is a scientific discipline and must use systematic methods of inquiry to generate valid, reliable, and verifiable knowledge.
2. Sociological theories and explanations should not be based on speculation, imagination, or guesswork.
3. Sociology like the natural sciences can generate knowledge through systematic scientific procedures. In his early work, Comte referred to sociology as “social physics,” reflecting his belief that the methodological principles of physics could be applied to the study of society.
4. Comte challenged the prevailing view that natural sciences are inherently more precise than social sciences, arguing that social phenomena, like natural phenomena, can be studied scientifically to produce objective and accurate knowledge.
5. He emphasized the use of systematic procedures in sociological research, including experimentation, measurement, observation, testing, and verification.
6. Comte addressed the issue of value judgment in social sciences, asserting that researchers must remain objective and avoid allowing personal beliefs, emotions, or values to influence their analysis.
7. He also proposed the “law of three stages,” which explains the development of human thought. According to this theory:
• In the theological stage, phenomena are explained in terms of divine or supernatural forces.
• In the metaphysical stage, explanations combine abstract reasoning with residual belief in supernatural influences.
• In the positive stage, phenomena are understood through rational and scientific explanations based on empirical evidence.

In the final, positive stage, human thought reaches its highest level of development, relying exclusively on scientifically verifiable facts while rejecting untestable assumptions. Thus, positivism becomes the dominant framework for the systematic and scientific study of social phenomena.

The branches of knowledge, such as physics, chemistry, biology, mathematics, economics, psychology, and geology, have undergone significant changes throughout history. In the very beginning, all these branches of knowledge were viewed as a single body of knowledge, collectively known as philosophy. The term philosophy, meaning “love of wisdom,” was used by ancient Greek philosophers to refer to the collective body of knowledge during the pre-Socratic period.

Although the history of philosophy can be traced back to the pre-Socratic period, ancient Greek philosophers such as Socrates (470 BC – 399 BC), Plato (428 BC – 348 BC), and Aristotle (384 BC – 322 BC) are widely regarded today as the founders of philosophy. Philosophy was initially divided into three main branches: (1) natural philosophy (physics), (2) moral philosophy (ethics), and (3) metaphysical philosophy (the study of the existence of things in the world). Later, various areas of philosophy, such as physics, chemistry, biology, and mathematics, gradually emerged as separate and independent disciplines at different points in history, particularly up to the 18th century.

The subject matter of each branch of knowledge was expanded and shaped by the contributions of thinkers and philosophers across different historical periods. Until the 12th century, most thinkers and philosophers developed theories and ideas based on their personal experience and wisdom. These theories were largely based on the speculations of learned individuals rather than on the scientific method, which involves systematic procedures such as experimentation, measurement, observation, testing, and statistical verification. Although some of these theories remain valid today, many were later proven incorrect when subjected to scientific testing over time. For this reason, the traditional approach to knowledge construction was increasingly criticized and challenged, particularly as systematic tools and procedures began to develop, enabling scholars to test earlier theories.

Many philosophers recognized the need to apply the scientific method for the acquisition of valid, reliable, and verifiable knowledge that could truly be classified as scientific. This shift became more pronounced as the period commonly referred to as the Dark Ages came to an end and the Renaissance (the age of reawakening) began to emerge after the 12th century. The community of scholars and scientists grew steadily over time. Figures such as Albertus Magnus (1193–1250), Thomas Aquinas (1225–1274), Roger Bacon (1210–1293), Francis Bacon (1561–1626), Galileo Galilei (1564–1642), and Isaac Newton (1642–1727) were among the early influential scholars and scientists who contributed to the advancement of knowledge through scientific procedures.

The systematic application of scientific methods became particularly evident between the 16th and 17th centuries, a period commonly known as the Scientific Revolution. For example, in the 17th century, the microscope had advanced sufficiently to allow the magnification and detailed study of human cells, which later contributed to the development of cell theory in biology.

Similarly, scholars and scientists of the Age of Enlightenment (the age of reason) in the 18th century emphasized the importance of scientific knowledge grounded in rational reasoning. Thinkers such as Francis Bacon, Thomas Hobbes, René Descartes, and others associated with the Scientific Revolution played a crucial role in introducing a new paradigm for understanding the world through scientific inquiry.

Inspired by these developments during the Age of Enlightenment, Auguste Comte (1788–1857) published six volumes of The Course of Positive Philosophy in 1830, 1835, 1838, 1839, 1841, and 1842, respectively, to emphasize the importance of scientific techniques for the investigation and acquisition of knowledge in both natural and social sciences. He also published A General View of Positivism in 1848 to elaborate on the proper nature of scientific procedures of inquiry.

Comte argued that the scientific method should involve experimentation, measurement, observation, testing, and verification. The application of these techniques enables the acquisition of knowledge that is universally valid and empirically verifiable. These ideas, as presented in The Course of Positive Philosophy and A General View of Positivism, form the foundation of modern positivism.
