Do we really know what is meant by scientific temper?

A geologist pinged me today to ask, “Nehru studied geology at Cambridge University … I wonder how much he used his science in office?”

I’m not great with history, but I know many fellow Indians are aware that “to develop scientific temper” is the constitutional duty of every citizen. I’ve heard that quoted by those who understand the value of science, but what about others?

And how many of those who understand the value of science understand what is really meant by scientific temper? I think it’s worth repeating what Nehru said in “The Discovery of India”, which he wrote while he was imprisoned following the Quit India movement.

[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.

Among our elders we still have those who lived under imperial rule, but there are fewer of them every passing year. That may be one reason another quote of Nehru may not have the effect that he intended.

While religion tends to close the mind and produce intolerance, credulity and superstition, emotionalism and irrationalism [sic], and a temper of a dependent, unfree person, a scientific temper is the temper of a free man.

If you have a few minutes to spare today, I wish you will give these words some thought.

Religion and intelligence

More than 400 years before the birth of Jesus of Nazareth, Greek playwright Euripedes wrote in his play Bellerophon, “Doth some one say that there be gods above? There are not; no, there are not. Let no fool, led by the old false fable, thus deceive you.”

Euripides was not an atheist and only used the word “fool” to provoke his audience. But, if you look at the studies conducted over the past century, you will find that those with religious beliefs will, on the whole, score lower on tests of intelligence. That is the conclusion of psychologists Miron Zuckerman and Jordan Silberman of the University of Rochester and Judith Hall of Northeastern University, who have published a meta-analysis in Personality and Social Psychology Review.

Malaria vaccine

Several vaccines for malaria have been developed over the past few decades, but none offer complete protection. Now, for the first time, US researchers have developed a vaccine that protects 100% of those given five doses of the vaccine.
