Umberto Eco, writing in 2005, about religion’s role in our age.

Human beings are religious animals. It is psychologically very hard to go through life without the justification, and the hope, provided by religion. You can see this in the positivist scientists of the 19th century.

They insisted that they were describing the universe in rigorously materialistic terms – yet at night they attended seances and tried to summon up the spirits of the dead. Even today, I frequently meet scientists who, outside their own narrow discipline, are superstitious – to such an extent that it sometimes seems to me that to be a rigorous unbeliever today, you have to be a philosopher. Or perhaps a priest. . . .

G K Chesterton is often credited with observing: “When a man ceases to believe in God, he doesn’t believe in nothing. He believes in anything.” Whoever said it – he was right. We are supposed to live in a sceptical age. In fact, we live in an age of outrageous credulity.
