Famous quotes containing the word important:
“Though it is very important for man as an individual that his religion should be true, that is not the case for society. Society has nothing to fear or hope from another life; what is most important for it is not that all citizens profess the true religion but that they should profess religion.”
—Alexis de Tocqueville (1805–1859)
