Asserting that India's tradition of debate and an open spirit of enquiry is critical for economic growth, he said encouraging challenge to all authority and tradition would rule out anyone imposing a particular view or ideology because of power.
Against the backdrop of growing intolerance in the wake of Dadri lynching and subsequent acts of violence, he also said protection of right to question and challenge was essential for India to grow.
"Finally, respect requires that in the rare case when an idea is tightly associated with a group's core personality, we are extra careful about challenging it," Rajan said delivering the convocation of IIT, Delhi, his alma mater.
He said tolerance can take the offence out of debate and indeed instill respect.
Citing the example of United States where burning of the national flag no longer triggers a reaction because the society over time has become tolerant of the act, the Governor said it is also no longer used as an instrument to shock.
He quoted Mahatma Gandhi to say "the golden rule of conduct is mutual toleration, seeing that we will never all think alike and we shall always see truth in fragments and from different points of view.
