• Sociology is the youngest member of the social sciences family.
• It is popularly known as the “Science of Society” because its main goal is the complete and comprehensive study of human society on a scientific basis.
• The word itself comes from the Latin word “Socius” (meaning companion) and the Greek word “logos” (meaning science or study).
• Auguste Comte’s Definition: He stated that “Sociology is the Science of Social phenomena Subject to natural and invariable lows”.
• Max Weber’s Definition: He defined it as “the Science which attempts the interpretative understanding of Social action in order there by to arrive at causal explanation of its cause and effects”.
• Emile Durkheim’s Definition: He kept it very simple, stating that “Sociology is the Science of institutions”.

According to Robert Bierstedt, sociology has several unique characteristics:

• Independent Science: It is not a branch of any other subject like philosophy; it has its own subject matter and theories.
• Social Science: It focuses completely on humans, their social behavior, and social life, unlike physical sciences.
• Categorical Discipline: It is ethically neutral and studies society “as it is,” rather than telling us how it “ought to be”.
• Pure Science: Its primary goal is to acquire knowledge about society, rather than just applying that knowledge practically.
• Abstract Science: It studies the general patterns of human events (like the general concept of “war” or “family”) rather than studying one specific, concrete historical event.

• Sociology emerged during a time of massive changes in Europe brought on by two major revolutions.
• The French Revolution (1789): This was an immediate factor that highlighted ideas like liberty, equality, and individual rights. However, it also brought political chaos and disorder, making thinkers realize they needed to find new ways to establish social order.
• The Industrial Revolution: Starting in 18th-century England, this revolution replaced simple village life with factory systems, mechanization, and complex urban living.
• Masses of people left rural areas for cities, leading to huge social problems like overcrowding, poor sanitation, poverty, and crime.
• Thinkers like Auguste Comte and Karl Marx were disturbed by these problems and felt an independent “Science of Society” was urgently needed to find solutions, which gave birth to sociology.

In his book “What is Sociology?”, Alex Inkeles provided a widely accepted outline of sociology’s subject matter:

• Analysing human culture and society: Sociology focuses on how human societies and cultures evolve, trying to reconstruct the stages of this evolutionary process.
• Analysing primary units of social life: It studies the basic building blocks of society, like social relationships, groups, and communities (urban, rural, and tribal).
• Studying basic social institutions: It dives deep into institutions that serve human needs, such as the family, religion, economy, and education.
• Highlighting fundamental social processes: Society is dynamic, so sociology studies the processes that cause change, like co-operation, competition, assimilation, and social conflict.

• Auguste Comte is proudly recognized as the “Father of Sociology”.
• He was the very first person to introduce the term “Sociology” in 1839 during his lectures on “Positive Philosophy”.
• He believed that this new science should study society using the scientific method and objectivity, just like how natural sciences explain the physical world.
• Comte divided sociology into two main parts: “Social Statics” (which deals with major institutions like family) and “Social Dynamics” (which deals with social change and progress).
• He also introduced the “Law of Three Stages” (Theological, Metaphysical, and Positive) to explain how human thinking has evolved over time.

• Herbert Spencer, an English philosopher, is often called the “second Father of Sociology”.
• He was deeply influenced by Charles Darwin and tried to apply the theory of biological evolution to sociology.
• He created the famous theory of “organic analogy,” where he boldly compared the structure of human society to a living biological organism.
• Spencer developed a theory that society evolves from simple forms to complex forms, categorizing them into “militant society” and “industrial society”.
• He stressed that society must be studied as a whole unit because all its different parts are interrelated and interdependent.

• Emile Durkheim was a French philosopher who believed social life must be studied with the exact same objectivity that scientists use to study nature.
• He introduced the “Rules of sociological method” to establish a truly scientific study of society.
• He is famous for the concept of “Social facts,” which are societal rules, laws, and customs that we inherit through education and that control our behavior externally.
• Durkheim famously studied suicide as a social fact caused by external social forces, dividing it into four types: Egoistic, Anomic, Altruistic, and Fatalistic.
• He also emphasized the universal nature of religion, stating that it plays a vital role in holding society together.

• Dr. G.S. Ghurye: He is celebrated as the “Father of Indian sociology” for his massive role in popularizing the subject in India. He conducted an elaborate study of the Indian caste system, writing the famous book “Caste and Race in India”. He was also the mastermind behind the formation of the “Indian sociological society” and the “Sociological Bulletin”.
• Dr. Iravati Karve: She was a brilliant student of Dr. Ghurye and became the first “Woman Sociologist of India”. Her specialized interest was understanding Indian society and its institutions through the lens of kinship. She wrote the famous book “Kinship organization in India” and even won a Sahitya Academy award for her Marathi book “Yugantha”.

• Common sense is knowledge based on popular wisdom, commonly held beliefs, guesses, and haphazard trial-and-error.
• Sociology, on the other hand, is based on the systematic and scientific analysis of facts.
• Common sense is not always reliable or true. For example, it was once “common sense” to believe that the earth was flat or that big objects fall faster than small ones.
• Unlike everyday people, sociologists do not accept something as a fact simply because “everyone knows it”.
• In sociology, every piece of information must be carefully tested, recorded, and analyzed scientifically before drawing a conclusion.

According to modern trends in sociology, the discipline has been greatly shaped by 20th-century thinkers. Five famous names include:

• G.H. Mead (1863-1931).
• C.H. Cooley (1864-1929).
• Talcott Parsons (1902-1979).
• Robert Merton (1910-2003).
• Michel Foucault (1923-1984).

• A pure science is a branch of knowledge where the main goal is simply “knowledge for knowledge’s sake,” without worrying about its immediate practical use.
• Sociology is classified as a pure science because its immediate goal is to acquire knowledge about human society, not to figure out how to utilize that knowledge.
• The main objective of pure sociology is to investigate the fundamental rules of social structure and how societies change.
• In their capacity as pure scientists, sociologists do not pass laws, determine public policies, or actively try to cure social ills like poverty or blindness.

• Applied science is all about using scientific knowledge to actively solve practical real-world problems.
• Applied sociology takes the theories and knowledge discovered by pure sociologists and uses them to improve social life.
• While a pure sociologist just wants to understand society, an applied sociologist wants to use that understanding to control and fix social issues.
• The ultimate goal of applied sociology is to bring about social welfare.
• For example, studying how a slum is structured is pure science, but creating a plan to stop crimes or remove poverty in that slum is applied science.

Applied sociology is divided into five exciting branches:

• Clinical Sociology: Using sociological knowledge alongside psychologists to help diagnose and treat individuals and organizations.
• Social Engineering: Using sociology to deliberately design social policies or institutions for planned social change.
• Social Work: Applying sociological principles directly to actual social problems to help people.
• Applied Social Research: Conducting surveys or evaluation research to estimate the potential effects of a new program or policy.
• Action Sociology: When sociologists actively participate in the development process to solve vital problems (like Bindeshwar Pathak starting the Sulabha Souchalaya in India).

• Laboratories: Physical sciences use artificially created laboratories where scientists have total control. In social science, the whole society is the laboratory, and it cannot be artificially controlled.
• Subjects of Study: Physical sciences study non-living objects (like rocks and chemicals) that don’t resist. Social sciences study living human beings who might become uncooperative or change their behavior when they know they are being studied.
• Predictability: Physical scientists can make dependable predictions (like predicting an eclipse). Social scientists find it almost impossible to predict human behavior accurately.
• Causation: In physical sciences, cause-and-effect is very clear (e.g., bacteria cause disease). In social sciences, causes are complicated and interlinked (e.g., figuring out if poverty causes illiteracy or if illiteracy causes poverty).

• A new generation of 20th and 21st-century thinkers, like Michel Foucault, Jurgen Habermas, Pierre Bourdieu, Jacques Derrida, and Anthony Giddens, have greatly influenced modern sociology.
• These thinkers invented entirely new concepts to use as tools for sociological research, such as Habitus, Deconstruction, and Structuration.
• Through their hard work, they developed exciting new perspectives to view the rapidly changing world.
• Some of these major new perspectives include post-industrialism, post-structuralism, post-modernism, neo-functionalism, and neo-Marxism.

Science is essentially a systematic body of knowledge that is obtained exclusively through the “scientific method”.

Its primary characteristics include:

• Factuality: Science is based on observed facts, not on imagination.
• Causality: It explores cause-and-effect relationships, proving that events don’t just happen randomly (e.g., harmful bacteria cause diseases).
• Universality: Scientific findings are universally valid everywhere, not limited to one country or religion (e.g., fire always burns).
• Predictability: Science tries to foretell future events based on facts.
• Verifiability: Any scientific statement must be testable and verifiable.
• Objectivity: Facts must be interpreted without any personal bias or judgments.

• Karl Marx is considered one of the founders of modern sociology thanks to his brilliant theories on social change, conflict, and revolution.
• He argued that human society progresses through different stages, and he believed that the current stage of Capitalism would eventually be replaced by Socialism.
• According to Marx, “Class Conflict” is the absolute key to understanding history. He famously stated that the history of society is nothing but a conflict between the wealthy capitalists and the poor laborers.
• He strongly emphasized that the economic structure forms the foundation of every social system and shapes people’s ideas and beliefs.
• Some of his most influential books include “The Manifesto of Communist Party” and “Das Capital”.

• In developing or underdeveloped countries, social factors are often the hidden reason behind economic backwardness.
• Economists have realized that they need sociological information to fix their countries, which is why it is said that an “Economist should be Sociologist also”.
• Sociology also plays a massive role in government social planning and policy-making.
• The government relies on the suggestions of expert sociologists to formulate policies regarding population control, pollution, and the rehabilitation of beggars.
• Furthermore, sociological knowledge is absolutely necessary to design welfare programs that uplift exploited and weaker sections of society, like SCs and STs.

• A.R. Desai was a prominent student of G.S. Ghurye who took a unique Marxist approach to sociological studies in India.
• Because of this, he is widely considered to be a “Marxist Sociologist”.
• His most famous work is “The social back ground of Indian nationalism,” where he offered a Marxist analysis that focused heavily on economic processes and divisions.
• He also wrote extensively about the “Welfare State,” describing it as a positive, democratic state that actively intervenes to implement social policies for the betterment of society.
• His influential book “Rural Sociology in India” became a major trendsetter for studying rural sociology in the country.

According to sociologist W.F. Ogburn, sociology proves it is a science through three major criteria:

• The Reliability of Knowledge: Science depends on reliable facts. Sociology has successfully gathered very reliable and dependable knowledge on topics like population, family behavior, and social change.
• The Organization of Knowledge: A science must be organized. Sociology successfully organizes its knowledge by finding relationships between different parts of society, such as connecting the dots between family, marriage, and social problems.
• Method of Study: Science requires a scientific method. Sociology uses several highly effective methods for its investigations, including the historical method, social survey method, and statistical method, to objectively discover the truth.

• Michel Foucault: He was a modern thinker who analyzed how “power” and “knowledge” are linked to control and discipline. In his writings on crime, madness, and sexuality, Foucault studied how modern institutions (like prisons, hospitals, and schools) emerged to monitor and control populations. He believed that expert knowledge acts as a force of control in society.
• Anthony Giddens: He invented the famous theory of “Structuration”. Unlike older thinkers, Giddens rejected the idea that “society” has a magical existence above and beyond individuals. Instead, he argued that human actions and reactions are the only true reality. He emphasized that sociology must focus on understanding the profound transformations happening in our modern lives, such as changes in marriage and family.

• Sociology is the youngest of the social sciences. Its etymological meaning is the “study of Society,” derived from the Latin word “Socius” (companion) and the Greek word “logos” (science or study).
• Thinkers have defined it in various ways:
  • Auguste Comte: “Sociology is the Science of Social phenomena Subject to natural and invariable lows”.
  • MacIver and Page: “Sociology is about Social relationships”.
  • Max Weber: “Sociology is the Science which attempts the interpretative understanding of Social action”.
  • Harry M. Johnson: “Sociology is the Science that deals with Social groups”.

According to Robert Bierstedt, sociology has several unique characteristics:

• It is an Independent Science: Sociology is not treated as a branch of another science like philosophy. It has its own unique subject matter, theories, and methods of approach.
• It is a Social Science, not a Physical Science: It concentrates its attention completely on humans, their social behavior, and social life.
• It is a Categorical Discipline: Sociology studies things “as it is” and not “as it ought to be”. It is ethically neutral and does not make moral value-judgments.
• It is a Pure Science, not an Applied Science: The immediate aim of sociology is simply the acquisition of knowledge, whereas an applied science is interested in utilizing that knowledge.
• It is an Abstract Science: It does not study particular, concrete instances (like a specific historical war). Instead, it studies the abstract forms and generalized patterns of human events (like social conflict or family in general).
• It is a Generalising Science: Sociology tries to make general rules based on the study of selected events, such as generalizing that joint families are more stable than nuclear ones.
• It is a General Social Science: Its area of inquiry is general, concerning all kinds of human activities in a general way.
• It is both Empirical and Rational: It is empirical because it emphasizes facts from observation, and it is rational because it relies on logical reasoning.

Sociology emerged as a separate discipline in the middle of the 19th century due to several major historical and intellectual factors:

• The French Revolution (1789): This was the most immediate factor. The revolution emphasized liberty, equality, and individual rights, but it also brought terrible chaos and disorder to society. Thinkers were disturbed by this and realized they needed to find a new basis for social order, which supported the emergence of sociology.
• The Industrial Revolution: Beginning in 18th-century England, this revolution replaced simple domestic industries with factory systems and mass production. Peasants flocked to cities, creating massive urban problems like housing shortages, poor sanitation, crime, and alcoholism. Thinkers like Comte and Marx advocated for a separate science of society to find solutions to these massive new social problems.

• The Age of Enlightenment and the success of natural scientists (who gave society technology like steam engines and printing presses) inspired social thinkers.
• Thinkers like Comte and Durkheim wanted to model sociology after successful physical sciences, proving that the scientific method could be used to study the social world.

• Colonial powers like England and France came into contact with very different cultures in their colonies.
• This exposure raised fresh questions: Why were some societies more advanced? Why was the rate of social change different everywhere?. The new science of sociology emerged to find convincing answers to these questions.

Though sociology is a young science, it has a distinct subject matter. Alex Inkeles outlined the general fields of sociology as follows:

• Sociological analysis of human culture and society: The major concern of sociology is human society and culture. A sociologist studies the evolution of society and tries to reconstruct the major stages in this evolutionary process. It analyzes the historical transformations of society using the scientific method.
• Analysing the primary units of social life: Sociology gives deep attention to the basic building blocks of society. It studies social acts, social relationships, individual personalities, groups of all varieties, and communities like urban, rural, and tribal populations.
• Studying the Nature and Functions of Basic Social Institutions: Any social system is built on the foundation of institutions. Sociology delves into the origin, structure, and functions of institutions like the family, kinship, religion, economy, politics, and education, which serve man’s most important needs.
• Throwing Light on Fundamental social processes: Human society is dynamic, and this is reflected in “social processes”. Sociology studies processes like co-operation, competition, assimilation, social conflict, stratification, and social change.
• Specialised fields: In the modern era, sociologists have created specialized fields of inquiry like the sociology of knowledge, sociology of history, industrial sociology, and sociology of religion.

• Auguste Comte is recognized as the “Father of Sociology” because he was the first to introduce the term “Sociology” in 1839 in his work “Positive Philosophy”.
• He wanted this new science to explain the laws of the social world just like natural sciences explain the physical world. He insisted that the study of society needs the scientific method with complete objectivity.
• He divided sociology into two parts: “Social Statics” (dealing with major institutions like family and religion) and “Social Dynamics” (dealing with social change and progress).
• He introduced the “Law of Three Stages” to explain how human intellect and society progress: The Theological stage (guided by religion), the Metaphysical stage (guided by abstract natural forces), and the Positive stage (based on an intellectual, scientific way of thinking).
• He also believed that sociologists must take on the responsibility of the “priesthood of humanity” to solve society’s problems.

• Spencer is an English philosopher often called the “second Father of Sociology”.
• As a famous evolutionist, he was deeply influenced by Charles Darwin and applied the theory of biological evolution to sociology.
• He created the theory of “organic analogy,” comparing human society to a living biological organism.
• Spencer developed a theory of two types of societies: “militant society” and “industrial society,” arguing that society evolves from simple forms to complex forms.
• He stressed that the whole society should be considered as a unit of study because its different parts are interrelated and interdependent. His major works include “Social Statics” and “Principles of sociology”.

Studying sociology has massive practical importance in our modern, complex society:

• Development of Personality: Humans are social beings who must adjust to changing conditions. Sociology provides comprehensive knowledge about society’s structure, problems, and individual rights, leading to the proper development of a person’s personality.
• Change in Attitudes: It helps us overcome deep-rooted prejudices about other people, religious hatred, and misconceptions. It helps us develop a critical, rational approach to the social world and build better relations with others.
• Solution of Social Problems: Every society faces issues like poverty, unemployment, terrorism, and overpopulation. Sociology helps us make an objective study of these problems and gives valuable suggestions to solve them.
• Social Planning and Policy Making: The government highly values sociological knowledge. Expert sociologists are needed to formulate government policies and social legislation regarding family, population control, and beggar rehabilitation.
• Promote Welfare of Backward Sections: In India, weaker sections like SCs and STs have been exploited for centuries. Sociological knowledge is absolutely necessary to promote effective welfare programs for these groups.
• Attractive Career: Sociology is a popular teaching subject and is included in competitive exams like IAS, IPS, and KAS, offering employment in fields like social welfare and public administration.
• Role in Developing Countries: Economists have realized they cannot fix economic backwardness without sociological information, proving that “Economist should be Sociologist also”.
• Understanding Modern Situations: It keeps us informed about recent changes and developments around us, making us conscious of our responsibilities towards society.

Since its birth, there has been a debate about whether sociology is truly a science. According to scholar W.F. Ogburn, sociology proves it is a science through three major criteria:

• The Reliability of Knowledge: Science depends upon reliable knowledge. Sociology has successfully made a promising beginning by gathering highly reliable studies on topics like population, family, group behavior, and social change.
• The Organization of Knowledge: A true science rests on how the parts of knowledge relate to each other. Sociology is highly organized and has acquired dependable, impressive knowledge in areas like family, marriage, and social problems.
• Method of Study: A branch of knowledge is a science if it uses scientific methods. While physical sciences use laboratories, sociology uses robust methods like the historical method, case study method, social survey method, and statistical method to fruitfully discover the truth.
• Like any science, sociology values Factuality (basing findings on facts, not imagination), Causality (finding cause-and-effect relationships), and Objectivity (interpreting facts without personal bias). It is ethically neutral and allows facts to speak for themselves, proving its scientific nature.

In the 20th and 21st centuries, contemporary sociology has massively expanded and been divided into a wide range of specialized fields of research:

• Prominent Social Fields: These include the study of interpersonal relations, rural and urban life, marriage and family, social differentiation, stratification, and inequality. In India, the study of caste is a major field.
• Demographic and Political Fields: It includes studies on gender, population, demography, subaltern studies, economic sociology, political sociology, and educational sociology.
• Systemic and Global Fields: Sociology now heavily studies race and ethnicity, formal organizations, linguistics, criminology, gerontology (study of aging), social change, modernity, post-modernity, globalization, and world systems.
• Other Important Branches: The discipline branches into the sociology of religion, knowledge, law, work, occupations, and industries. It even covers the sociology of architecture, art, music, literature, health, illness, medicines, leisure, sports, tourism, popular culture, militarism, and sexuality.
• Modern popular textbooks also suggest subjects like socialization, norms and values, feminism, the concept of self, phenomenology, and post-modernism.

These modern thinkers have greatly influenced the course of modern sociology and its methods of investigation:

• For Bourdieu, the objective of sociology is to unveil the hidden culture of society.
• He believed sociologists should study the cultural practices of the masses rather than just the upper classes to uncover things like advanced forms of racism.
• As a neo-Marxist, he emphasized the “counterculture” of the proletariat.
• He argued against separating micro and macro sociology, instead calling for a “constructivist approach” to sociology. He also invented the concept of “Habitus”.

• He is a very influential social thinker known as the best spokesman of the Frankfurt School of Critical Theory, with a strong allegiance to Marxist thought.
• He severely criticized “positivism,” arguing that it actually limits our understanding of the social world.
• He severely critiqued capitalist societies, stating that their obsession with economic growth destroys the moral order and creates a lack of meaning in everyday life.

• A French philosopher and post-modernist whose ideas developed from linguistics.
• He introduced the popular concept of “deconstruction,” pleading for the deconstruction of old sociological texts written by founding fathers like Comte and Marx.
• He argued that these old texts demystified reality and that textual reading is not always correct. Deconstruction brings out what these texts excluded to help us truly understand society.

While both are classifications of science, they have distinct differences:

• Use of Scientific Method: Physical sciences have been using the scientific method effectively for a very long time to obtain desired results. Social sciences, however, face difficulties and have only applied this method in recent decades.
• Laboratory Conditions: Physical sciences use artificially created laboratories where the scientist has immense control over the experiment, conducting it at any suitable time. In social sciences, laboratory experiments are almost impossible because the whole society constitutes the laboratory, which cannot be artificially created at will.
• Objects of Study: Physical scientists study objects like rocks, molecules, and chemicals that are natural and do not resist study. Social scientists study living human beings who might resist study, prove uncooperative, or radically change their behavior when they know they are being observed.
• Predictability: Physical scientists have great control and can make dependable predictions (like eclipses). Social scientists find prediction and control very difficult because human behavior is highly unpredictable.
• Causation: In physical sciences, cause-and-effect relationships are clear and unambiguous (e.g., causes of diseases). In social science, causation is complicated and confusing (e.g., trying to figure out if illiteracy causes poverty, or if poverty causes illiteracy).
• Universality: Physical science generalizations are universal and not restricted to a fixed region. Social science investigations are very much confined to a fixed place, time, and culture, making generalizations less universal.

• Durkheim was a French philosopher who emphasized that society is a distinct reality and must be studied with the same objectivity as scientists study the natural world.
• He introduced the “Rules of sociological method” to ensure the scientific study of society.
• He introduced the concept of “Social facts,” stating that human behavior is guided by inherited duties, customs, and laws that exercise an external constraint on individuals.
• He famously studied suicide as a social fact caused by external forces, outlining four types: Egoistic, Anomic, Altruistic, and Fatalistic suicide.
• He highlighted the universal role of religion in holding society together and laid the foundation for specialized fields like the sociology of religion and law.

• Karl Marx was an immensely important thinker who advocated an end to exploitation. He is considered a founder of modern sociology due to his brilliant theories on social conflict and revolution.
• He argued that society progresses through stages and that “Class Conflict” is the absolute key to human history. He stated that the history of all existing society is the conflict between wealthy capitalists and laborers.
• Marx placed great emphasis on the economic structure, arguing that it forms the foundation of every social system and shapes people’s ideas and beliefs.
• He believed that the capitalist society would eventually be overthrown by a “class struggle” led by the working class, leading to a harmonious, classless society. His “conflict approach” remains highly helpful in understanding social phenomena today.

Sociology gained a foothold in India in 1919 at Bombay University, producing several brilliant thinkers.

• Dr. G.S. Ghurye: Known as the “Father of Indian sociology,” he functioned as the first head of the Department of Sociology at Bombay University. He carried out an elaborate study on the caste system, writing the famous book “Caste and race in India”. He studied everything from Indo-European kinship to Indian costumes and was the main force behind creating the “Indian sociological society”. He famously advocated for a policy of assimilation for tribal groups.
• Dr. M.N. Srinivas: A leading sociologist from Karnataka who wrote “Religion and society among the coorgs of south india,” establishing him globally. He analyzed social change in India by introducing iconic concepts like “sanskritisation” (lower castes adopting high caste ways of life), “Westernization,” and the “Dominant caste”.
• Dr. Iravati Karve: As a student of Dr. Ghurye, she became the first “Woman Sociologist of India”. Her specialized interest was understanding Indian society and social institutions strictly through the lens of kinship. She wrote the famous “Kinship organization in India” and won a Sahitya Academy award for her Marathi book “Yugantha”.
• A.R. Desai: A Marxist Sociologist who offered a Marxist analysis of Indian nationalism, giving prominence to economic processes in his book “The social back ground of Indian nationalism”. He wrote extensively on the “Welfare State,” describing it as a positive, democratic state that intervenes to better society.

• Pure Sociology: This is a branch of knowledge pursued strictly for “knowledge’s sake,” without concern for its practical use. The main goal of pure sociology is simply the acquisition of knowledge about human society and investigating fundamental rules of social structure and change. Pure sociologists do not try to fix public policy or actively cure social ills.
• Applied Sociology: This is the opposite; it is the search for ways to use scientific knowledge to actively solve practical problems. It takes the principles gained from pure science and applies them to bring about social welfare and control social reality. For example, studying a slum to understand it is pure science, but creating a plan to remove poverty there is applied science.

Applied sociology is divided into five main branches:

• Clinical sociology: Uses sociological knowledge alongside psychologists and social workers to provide diagnosis and assistance to individuals and organizations.
• Social engineering: Uses sociological knowledge to design social policies or institutions for a specific purpose, aiming at planned social change.
• Social work: A field where the principles of sociology are applied hands-on to fix actual social problems.
• Applied social research: Includes survey research and evaluation research to systematically estimate the effects of a proposed program or planned change.
• Action sociology: A form where sociologists are asked to actively participate in the development process and tackle vital problems head-on (e.g., Bindeshwar Pathak’s Sulabha Souchalaya).

• The word “science” comes from the Latin word “scientia,” meaning “knowledge”.
• In simple terms, it is a systematic body of knowledge that has been obtained specifically through the ‘scientific method’.

• Factuality: Science is not based on imagination; it is based on observed facts.
• Causation (Cause and Effect): Science assumes events do not occur randomly and explores the causal relationship between events (e.g., harmful bacteria cause diseases).
• Universality: Scientific truths have universal validity and are not limited to one race, religion, or region (e.g., fire always burns).
• Predictability: Science attempts to foretell future events, like making predictions about eclipses or rainfall.
• Verifiability: A scientific statement can only be accepted if it can be verified with empirical evidence.
• Objectivity and Value Neutrality: Scientists must interpret facts without personal bias and must not let their personal values influence their research.

• Sociology was fought for by its founding fathers to be established as a science.
• According to W.F. Ogburn, it achieves this because it produces highly reliable knowledge (like population studies) and organizes this knowledge impressively.
• Most importantly, sociology insists on the scientific method. It uses strict procedures like the historical method, statistical method, and social survey method to objectively discover the truth, proving it operates as a true science.
