Scientific knowledge and scientific temper Tnpsc

Scientific temper, this word was used by Prime Minister of India, Jawaharlal Nehru in 1946. It is also mentioned in the Indian constitution, Article 51A.

As per Article 51A, “To develop scientific temper, humanism and the spirit of inquiry and reform” is one of the fundamental duties of the people of India.

The Scientific is a way of life that uses the scientific method and which may consequently include questioning, observing physical reality, testing, hypothesizing, analyzing, and communicating.

The idea of the scientific temper is expressed earlier by Charles Darwin when he said, “Freedom of thought is best promoted by the gradual illumination of men’s minds, which follows from the advance of science”. Check Charles Darwin’s book on The Descent Of Man to know more.

Karl Marx said religion is the reason for people’s problems and he wised religion should be abolished. Karl Marx said that “Religion is the sigh of the oppressed creature, the heart of a heartless world, and the soul of soulless conditions. It is the opium of the people. The abolition of religion as the illusory happiness of the people is the demand for their real happiness. To call on them to give up their illusions about their condition is to call on them to give up a condition that requires illusions.”

“[What is needed] is the scientific approach, the adventurous and yet critical temper of science, the search for truth and new knowledge, the refusal to accept anything without testing and trial, the capacity to change previous conclusions in the face of new evidence, the reliance on observed fact and not on pre-conceived theory, the hard discipline of the mind—all this is necessary, not merely for the application of science but for life itself and the solution of its many problems.” —Jawaharlal Nehru (1946) in the book The Discovery of India.
