What if fear, rather than truth, lies at the root of belief?
In Superstition in All Ages, Paul-Henri Thiry d'Holbach puts organized religion before the test of common sense. This short, fierce work of French Enlightenment philosophy asks how people explain a world they do not understand—and argues that fear and ignorance give rise to gods.
From that starting point, d'Holbach turns to power, doctrine, and morality. He argues that priests and rulers profit from belief, challenges teachings he sees as contradictory, and asks whether goodness needs religion at all. Written for ordinary readers rather than scholars alone, the book offers a direct encounter with arguments that alarm church and state.

Superstition in All Ages is a short, fierce argument against organized religion. It comes out of the French Enlightenment, the circle of thinkers around Baron d'Holbach in Paris in the eighteenth century.
From the 15-minute summary · Key idea 1
Fear and ignorance give birth to gods
The book traces religion back to fear and ignorance. People, it argues, first met a world they could not explain. Fear made those powers into gods, and ignorance kept them alive.
The author treats this as a question of cause and effect. Where people understand nature, they have less need of invisible agents. Where they do not, imagination fills the gap with spirits and demons. The argument is that superstition is not a sign of deep wisdom but a habit of mind that grows from not knowing.

What is Superstition in All Ages about?
It is an argument against organized religion. It claims that belief grows from fear and ignorance, that priests and rulers profit from it, and that morality can rest on reason and human nature instead.
Who wrote Superstition in All Ages?
The work comes from the circle of Baron d'Holbach, who is named as its author. Its English title has also long been linked to Jean Meslier, a French priest whose atheist ideas the circle helped spread.
When was Superstition in All Ages written?
It belongs to the French Enlightenment of the eighteenth century. Works of this kind were often printed in secret, outside France, under false names, because the church and the crown censored attacks on religion.
