Dr.Narendra DhabolkarThe Scientific temper is a way of life which uses the scientific method and which may, consequently, include questioning, observing physical realitytestinghypothesizing, analysing, and communicating (not necessarily in that order). "Scientific temper" describes an attitude which involves the application of logic. Discussion, argument and analysis are vital parts of scientific temper. Elements of fairness, equality and democracy are built into it. Jawaharlal Nehru was the first to use the phrase in 1946. He later gave a descriptive explanation:

"[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) The Discovery of India
