The monster, fanaticism, still exists, and whoever seeks after truth will run the risk of being persecuted.
VoltaireLet us therefore reject all superstition in order to become more human; but in speaking against fanaticism, let us not imitate the fanatics: they are sick men in delirium who want to chastise their doctors. Let us assuage their ills, and never embitter them, and let us pour drop by drop into their souls the divine balm of toleration, which they would reject with horror if it were offered to them all at once.
Voltaire
