Markandey Katju (Judge of the Supreme Court of India):
Science is that knowledge by which we can understand nature
(and human society) and use the knowledge for our benefit.
For doing so, the scientists rely on reason, observation, and experiment.
This obviously can not be done on the dictates of any one
(though the government can certainly create the atmosphere where these can flourish).
Science and democratic values go hand in hand.
In science, there is no final word, unlike in religion.
Science questions everything and does not take anything for granted.
