With Indian independence and coming of Indian Constitution; the foundations for progress in the society were laid. This was to be for an all out progress and the basis of this was the principles of scientific temper. This process was guided by the architect of modern India, Jawaharlal Nehru. We saw the surge of the institutions which contributed to the progress of the country; with great contributions of Indian scientists. There were flaws and weaknesses, of course, but the direction was a rational, direction was that of scientific approach. This fulfilled the clause of the Article 51a of the Indian constitution which enjoins upon citizens the “fundamental duty” to develop “the scientific temper”.
