The case shows us that we men, including the greatest and best of us, may fall at any time under the dominion of such a mania, unless we are trained in methods of critical thinking. A series of great sceptics from Montaigne to Voltaire met the witch doctrines with scorn and derision. They were not afraid to deny the existence of demons. It appears also that the so-called common-sense of the crowd revolted at the absurdities of witchcraft. Every person who was executed as a witch named, under torture, others, who were then arrested, tortured, and executed; each of these named others, and so the witch-judges found that they were driven on, by judicial execution of the most cruel form, to depopulate a whole territory. It was a critical revolt when they saw this construction of their own conduct and turned against it. When we read the story we are amazed that good and honest men could have gone on for centuries inflicting torture of the extremest kind on old women without the bit of critical reflection which should have led them to ask themselves what they were doing.

Let us not make the mistake of supposing that all follies and manias of this kind are permanently overcome and need not be feared any longer. The roots of popular error are ineradicable; they lie at the bottom of human nature; they can produce new growth and new fruits at any time.

The modern world has rejected religious dogmatism, but it has taken up a great mass of political dogmatism, and this dogmatism is intertwined with the interests of groups of men. If you accept the political dogmas of the eighteenth century and begin to build deductions on them you will reach a construction as absurd and false as that of witchcraft. The only security
