Auguste Comte, a French philosopher, proposed a classification of the sciences in his work System of Positive Polity in 1854. This classification also draws its insight from his other written works such as ‘Law of Three Stages’ and the six volumes of ‘The Course of Positive Philosophy’ published from 1830 to 1842.

Comte believed that sciences have varying degrees of complexity, generality, and interdependency. He was of the view that some sciences are complex while others are simple. Some sciences are more dependent on other sciences, while others are less dependent on other sciences. Similarly, some sciences are very general while others are very specific. Based on these characteristics of sciences, Comte classified sciences into six categories: 1. Sociology, 2. Biology, 3. Chemistry, 4. Physics, 5. Astronomy, and 6. Mathematics

Comte classified sciences based on the following criteria:

1. The order of increasing complexity or simplicity of sciences.
2. The order of their increasing dependence on one another.

 

According to Comte, the degree of complexity or simplicity of sciences was another criterion for the classification of sciences. He believed that some scientific disciplines are complex while others are simple.

In terms of the complexity of the subject matter of different sciences, Comte viewed Sociology as the most complex science. He was of the view that social phenomena are multi-dimensional and linked with many observable as well as unobservable dynamics. This is because, in order to understand human behaviour, we need to consider its social, biological, and psychological dynamics, which may directly or indirectly shape the behaviour of an individual.

For instance, to understand the aggressive behaviour of an individual in a social setup, we must look at different factors such as circumstantial factors, prevailing social norms and values, emotional state of mind, religiosity, social influence, economic considerations, and so on. These are some factors that generally influence human behaviour. However, there can be several other unobservable factors and motives that may lead to aggressive behaviour. This means that social phenomena are complex because one has to consider their various dimensions to understand them in their entirety. For this reason, Comte viewed Sociology as the most complex science among all scientific disciplines.

Comte arranged the scientific disciplines in the order of their complexity as follows:

1. Sociology, 2. Biology, 3. Chemistry, 4. Physics, 5. Astronomy, and 6. Mathematics

He believed that Sociology is the most complex science, whereas Mathematics is the simplest science. Every science in the given order is more complex than the science that follows it. For instance, Sociology is a more complex science than Biology. Biology is more complex than Chemistry. Chemistry is more complex than Physics, and so on.

Auguste Comte’s classification is linked with his theory Law of Three Stages. According to Comte’s theory, human thought has evolved in three stages over the course of history. These stages are: 1) Theological Stage, 2) Metaphysical Stage, and 3) Positive or Scientific Stage.

According to Comte, human thought evolved through these three stages such that thinking in each stage became more rational than in the preceding stage. In the Theological Stage, human beings believed that everything was governed solely by divine powers. In the Metaphysical Stage, they believed that events were governed partially by divine powers and partially by rational factors. In the Positive or Scientific Stage, human beings believed that everything is governed entirely by rational factors, which can be explored scientifically.

Comte argued that, as human thought became increasingly rational in a stage-wise manner, a similar effect was observed in knowledge across these stages. Each academic discipline progressed through these three stages to become a true science. The degree of rationality and objectivity in each discipline increased stage by stage, with disciplines in each stage being more rational and objective than in the preceding stage. Through this process, some disciplines reached the Positive or Scientific Stage earlier than others. In the order of reaching the scientific stage, Mathematics was the first discipline to enter the scientific stage, while Sociology was the last.

In terms of reaching the scientific stage, the six sciences follow this order:

1. Mathematics
2. Astronomy
3. Physics
4. Chemistry
5. Biology
6. Sociology

Thus, Mathematics was the first to reach the scientific stage, and Sociology was the last.

Auguste Comte, a French philosopher, is known as the founder of Sociology. He coined the term ‘Sociology’ for the first time in 1838. He sought to establish Sociology as an independent scientific discipline because, before 1838, it was considered a branch of philosophy. The purpose of classifying the sciences was to provide a foundation for this newly emerging discipline, as well as to demonstrate that Sociology is a purely scientific field.

Comte’s efforts to project Sociology as an independent science are reflected in his six volumes of The Course of Positive Philosophy and in the Law of Three Stages. In these works, he discussed all the sciences (e.g., Physics, Chemistry, Mathematics, Biology, and Astronomy) and laid the foundation for the new social science, Sociology, which is the scientific study of human society. He emphasized the role of Sociology in understanding the structure and functioning of human society for social development.

As noted, that Sociology did not exist as an independent science before 1838, to establish Sociology as an independent discipline, Comte classified the sciences to specify the place of Sociology among other sciences. In addition to establishing Sociology as an independent discipline, Comte’s aim was to also establish it as a purely scientific discipline. Therefore, his classification reflected where does this new science lie among other scientific discipline and how does it work in relation to other scientific disciplines. Similarly, he believed that like other sciences the Sociology has also reached its positive or scientific stage and qualifies for being called a science.
