The Teacher We Need: From Memorising Knowledge to Creating New Thought
On Teachers’ Day, a question worth asking: Are our educational institutions producing genuine seekers of knowledge—or merely efficient transmitters of information?
Justice Markandey Katju
The great Chinese philosopher and scholar Confucius offered, centuries ago, a profound definition of what constitutes a genuine teacher. In his Analects, he emphasised the importance of revisiting existing knowledge while continually acquiring new understanding.
His celebrated observation is often rendered as:
“A genuine teacher never stops learning. He keeps cherishing his old knowledge, but is continually acquiring new knowledge, so as to be a teacher of others.”
The wisdom contained in these words remains remarkably relevant today.
For Confucius, teaching was never merely the mechanical transfer of information from a teacher to a student. Education was an interactive process—one that should awaken curiosity, encourage independent thought and inspire a student to continually improve himself or herself.
Indeed, despite being regarded as one of the greatest teachers in history, Confucius portrayed himself not as someone who possessed all knowledge, but as a lifelong seeker. He was prepared to learn from anyone, irrespective of social status or position. The underlying message was simple yet revolutionary: a teacher who has stopped learning has also begun to lose the essence of teaching.
Feynman and the difference between education and learning
A similar lesson can be found in the life and work of the celebrated American theoretical physicist Richard P. Feynman (1918–1988).
Feynman made pioneering contributions to quantum mechanics, quantum electrodynamics and the study of superfluidity. He was also involved in the Manhattan Project during the Second World War, contributed to the development of the conceptual foundations of nanotechnology and was awarded the Nobel Prize in Physics in 1965, jointly with Julian Schwinger and Sin-Itiro Tomonaga, for their contributions to quantum electrodynamics.
But Feynman’s significance extends far beyond his scientific achievements. He was equally renowned for his approach to teaching and his insistence upon genuine understanding rather than rote learning.
During an academic year spent teaching in Brazil, Feynman was invited to speak about his experience before an audience comprising students, professors and government officials. He agreed on one condition: he should be allowed to say whatever he wished.
He then delivered a remarkably blunt assessment of the Brazilian education system.
Feynman told his audience, in substance, that the principal purpose of his talk was to demonstrate that science was not really being taught in Brazil.
The statement shocked his audience. How could science not be taught when universities had classrooms, laboratories, courses, textbooks and thousands of students?
Feynman’s answer went to the heart of the problem.
Students, he observed, were memorising material from textbooks and reproducing it in examinations, but were not necessarily understanding the underlying scientific principles. They could pass examinations and even teach the same material to others, yet lacked the ability to independently investigate, experiment and discover.
For Feynman, experimentation was indispensable to scientific education. Without questioning, testing, observing and discovering, the memorisation of scientific facts could hardly be described as genuine scientific learning.
That distinction deserves serious consideration in India today.
The Indian education system: Information or inquiry?
India has produced some of the world’s finest scholars, scientists, teachers and intellectuals. Its educational institutions have also produced generations of professionals who have made significant contributions nationally and internationally.
Yet, alongside these achievements, there remains a troubling question: Are we cultivating a culture of inquiry, experimentation and independent thinking at the scale required by a country of India’s size and complexity?
The issue becomes particularly important in higher education.
Universities, engineering institutions and research centres should not merely prepare young people to pass examinations or secure well-paid employment. Their larger social purpose should be to cultivate minds capable of confronting the difficult problems confronting society.
India faces enormous challenges—poverty, unemployment, malnutrition, inadequate access to quality healthcare, educational inequality, environmental degradation and deep social divisions. Addressing such problems requires considerably more than memorised information.
It requires imagination, scientific temper, critical reasoning, experimentation and the courage to question established assumptions.
That is where the teacher assumes a role far greater than that of an instructor.
The robodog controversy and a larger question
The controversy surrounding a robotic dog displayed by Galgotias University at the AI Impact Summit in Delhi in 2026 provides an interesting illustration of the larger concern.
The university reportedly presented the robodog as an institutional creation, before questions arose about its actual origin and its connection with Chinese robotics company Unitree. The episode subsequently attracted considerable attention on social media.
Whatever the circumstances surrounding that particular incident, it raises a broader question that goes beyond one university or one robotic device:
Are our institutions sufficiently committed to originality, verification, experimentation and intellectual honesty?
In an age in which artificial intelligence can generate text, images, code and increasingly sophisticated technical material within seconds, the educational system has an even greater responsibility to teach students how to distinguish knowledge from information, originality from imitation, and understanding from reproduction.
The real test of an educational institution is not how impressive its display appears, but whether it can explain how something was conceived, developed, tested and improved.
A university must be more than a degree factory
A university should ideally be a laboratory of ideas.
It should be a place where students are encouraged to ask uncomfortable questions, challenge conventional wisdom, conduct experiments, examine evidence and develop solutions to real-world problems.
Unfortunately, the pressure to obtain degrees, secure employment and achieve economic stability can sometimes reduce education to a transactional exercise.
A student studies for an examination, obtains a degree and seeks a secure career. The teacher completes the syllabus, conducts examinations and moves on to the next academic cycle.
Somewhere in this process, the larger purpose of education can be lost.
The question, therefore, is not whether students know enough facts. The more important question is whether they have learned how to think.
Teachers are the intellectual conscience of society
Teachers occupy a unique position in any civilisation.
They do not merely transmit knowledge; at their best, they shape the intellectual and moral character of generations.
A teacher can teach a student a formula. A great teacher can teach the student how to discover a formula.
A teacher can explain an established theory. A great teacher can encourage the student to ask whether the theory itself can be improved.
A teacher can prepare a student for an examination. A great teacher prepares the student for life.
This is why teachers and genuine intellectuals may rightly be described as the eyes of society. They have the responsibility to identify social problems, question prejudice and ignorance, encourage scientific temper and illuminate possible paths forward.
But intellectual authority cannot be claimed merely through academic titles, publications or institutional positions. It must be earned through original thought, intellectual honesty, humility and a willingness to continue learning.
From rote learning to a culture of questioning
India’s educational challenge, therefore, is not simply about changing textbooks or introducing new technologies.
It is about changing the culture of learning itself. A student should not be discouraged from asking, “Why?” A teacher should not feel threatened when a student asks a difficult question. A university should reward originality rather than conformity. Research should be judged by its contribution to knowledge rather than merely by the number of papers produced. And academic success should not be measured exclusively by examination results, rankings or placement packages.
The ultimate measure should be whether education produces citizens capable of thinking independently and contributing meaningfully to society.
There is also a social dimension to this transformation. Caste prejudice, communal divisions and other inherited biases can survive when education teaches people what to think rather than how to think. Genuine education should broaden the mind, encourage empathy and enable individuals to examine inherited beliefs through reason and evidence.
Can we really celebrate Teachers’ Day without asking these questions?
Teachers’ Day is undoubtedly an occasion to honour the millions of teachers who work with dedication and sincerity. Many educators across India continue to inspire students despite limited resources and enormous challenges.
But celebration should not prevent introspection.
Perhaps the most meaningful tribute we can pay to teachers is not merely to exchange greetings and felicitate them with ceremonies and awards. It is to ask what kind of teachers and what kind of educational system—we wish to build.
Confucius reminds us that the genuine teacher remains a learner.
Feynman reminds us that memorising facts is not the same as understanding science.
Together, their lessons point towards a simple but powerful proposition:
Education must create minds that question, investigate, experiment and discover not merely minds that remember and reproduce.
India does not lack intelligent young people. What it needs is an educational environment capable of unlocking their intellectual potential.
And that transformation must begin with the teacher.
So perhaps, instead of asking only “How should we celebrate Teachers’ Day?”, we should ask a more fundamental question:
“What kind of teacher does India need for the future?”
The answer may determine not merely the future of our classrooms, but the future of the country itself.
