Carl Sagan on Indian Cosmology

Freedom of the mind created the wondrous world of the intellect — the world of Hindu rishis, philosophers, poets and dramatists. It was the freedom of the mind and freedom of the senses which led to India’s diversity and contributed to the richness of its civilization. No other civilization, not even that of the Greeks, could have enjoyed the freedom that we had. We have to remember, Socrates was forced to drink hemlock! The Inquisition burnt the Christian apostates at the stake and Islam beheaded dissenters.
