Scientific temper refers to a way of thinking rather than a specialized body of knowledge
On the death anniversary of Jawaharlal Nehru, the first Prime Minister of India
Jawaharlal Nehru, the first Prime Minister of India, was born on November 14, 1889, and died on May 27, 1964
“Beyond ideas, Nehru translated vision into structure by building a robust scientific infrastructure. He pioneered the establishment of premier institutions such as the Indian Institute of Technology, designed to produce world-class engineers and technologists for a newly independent nation. These institutions today enjoy global recognition, a testament to the foresight of investing in high-quality technical education in the early years of Independence.
Equally significant was his role in initiating strategic scientific programs. Under his leadership, India laid the foundations of its space and atomic energy programs, recognizing their long-term importance for national development and sovereignty. In 1962, the establishment of the Indian National Committee for Space Research marked the beginning of India’s journey into space science, eventually evolving into one of the world’s most successful space programs.”
Jawaharlal Nehru’s contribution to Indian science and technology was not merely administrative; it was deeply philosophical and transformative. When India had just emerged from colonial rule, it was economically fragile and scientifically underdeveloped. Nehru recognized that true independence required both intellectual and technological self-reliance. He placed science at the center of nation-building, believing that only a scientific approach could address India’s pressing problems. These included poverty, hunger and backwardness.
Nehru’s most enduring contribution was promoting scientific temper. He first explained this term in his well-known book, The Discovery of India, published in 1946. Scientific temper can be defined as a way of thinking and acting in social settings using scientific methods.
These may include posing questions, observing physical reality, testing hypotheses, hypothesizing, analyzing and communicating inferences, not always in this order. Ultimately, scientific temper describes an attitude that involves using logical reasoning.
This should not be mistaken for merely inculcating technological and scientific expertise or building infrastructure in science and technology; rather, the development of a scientific temper among the country’s masses is a philosophical and pedagogical objective.
For instance, India has achieved great success after Independence in the field of science and technology, as evidenced by milestones ranging from acquiring atomic power to the low budget yet highly successful Mangalyaan mission by the Indian Space Research Organization and the huge IT revolution it has driven. Scientific temper refers to a way of thinking or a viewpoint rather than a specialized body of knowledge.
It addresses the broader scope of human life rather than to narrow, specialized questions of scientific research and application. Unlike scientific expertise alone, the project of scientific temper is a call for the diffusion of scientific inquiry in the thoughts of the huge population of this country. The growth of scientific temper should be measured by the extent to which ordinary people use the methods of science in dealing with issues in their own lives.
Through the 42nd Amendment to the Indian Constitution in 1976, ‘scientific temper’ was added to the list of Fundamental Duties of every Indian citizen vide Part IV-A, Article 51-A (h): ‘to develop the scientific temper, humanism and the spirit of inquiry and reform.’
Beyond ideas, Nehru translated vision into structure by building a robust scientific infrastructure. He pioneered the establishment of premier institutions such as the Indian Institute of Technology, designed to produce world-class engineers and technologists for a newly independent nation. These institutions today enjoy global recognition, a testament to the foresight of investing in high-quality technical education in the early years of Independence.
Equally significant was his role in initiating strategic scientific programs. Under his leadership, India laid the foundations of its space and atomic energy programs, recognizing their long-term importance for national development and sovereignty. In 1962, the establishment of the Indian National Committee for Space Research marked the beginning of India’s journey into space science, eventually evolving into one of the world’s most successful space programs.
Nehru also ensured that science was integrated into economic planning. Through the Five-Year Plans, he linked scientific research with agriculture, industry and infrastructure, making technology a tool for national transformation rather than an isolated pursuit. Investment in research and development increased significantly during his tenure, reflecting the seriousness with which the state approached scientific advancement.
Perhaps the most remarkable aspect of Nehru’s legacy is that he did not view science as an elite activity confined to experts. He saw it as a civilizational shift — a way of thinking that would liberate society from superstition and stagnation.
His famous description of laboratories, dams, and institutions as the “temples of modern India” symbolized this belief that progress must be rooted in knowledge and innovation. The spirit of inquiry and the acceptance of the right to question and be questioned are fundamental to scientific temper.
It calls upon one to ask the how, the what, and the why of an object, event or phenomenon. It further calls upon one to exercise the right to question, provided, of course, the questioning of an existing theory, hypothesis, or statement, or social situation is done in accordance with the scientific method and is not merely a bare assertion of one’s belief.
Scientific temper is, therefore, incompatible with the acceptance of all kinds of authority figures or high priests who may not be questioned. It leads to the realization that events occur as a result of the interplay of understandable and describable natural and social forces and not because someone, however great, so ordained them. These forces are often complex and intertwined and have to be analytically disentangled.
It is the hard reality that we, unfortunately, project science merely as a body of knowledge. But science is more. Science is primarily a set of methods, a toolkit that we use to generate knowledge. In the method of science, we make observations and experiments and use evidence, logic and internal consistency to make decisions. More importantly, we are allowed to question and re-question everything. There is no final authority and no final answer. Science is thus always a work in progress; all answers are tentative and can be called into question at any time and by anybody.
This is the method of science, but this is not what we are projecting as science. We do not teach the scientific method in our schools. Instead, we burden our children with fact after fact, we burden their backs with bags full of books containing facts, but we do not tell them how we came to know all these facts, or indeed any fact.
Today, India’s achievements in engineering, space exploration and scientific research are built upon the foundations laid during Nehru’s era. His vision ensured that India did not remain a passive consumer of technology but began its journey towards becoming a creator of knowledge. In that sense, Nehru’s contribution to science and technology was not just about institutions or policies — it was about shaping the intellectual direction of a nation.
