A turning point in the fight against witch hunts

Friedrich Spee (1591–1635)
The Jesuit, theologian, and poet Friedrich Spee became famous as a courageous critic of the witch trials.
To this day, he is considered a champion of human dignity and justice.

A gray April morning in 1631: Outside the walls of Ringelstein Castle near Büren, a pyre crackles in the cold mist. A young woman, bound and exhausted, is dragged forward by a guard. Tears glisten on her cheeks as she proclaims her innocence one last time—but the mocking murmur of the crowd stifles her words. In the background stands Father Friedrich Spee, a Jesuit priest with a worried expression. As her confessor, he offered the woman comfort on her last night. Now he must watch as the flames blaze and an innocent soul perishes within them—like so many in those weeks. Internally shaken, Spee quietly recites a prayer, but at the same time, he vows to fight against this cruel injustice.

Such scenes occurred all too frequently in the Bishopric of Paderborn during those years.

In 1631, Friedrich Spee summoned his courage and published a book under a pseudonym that would make history: the Cautio Criminalis ("Legal Precaution"). This text – written in Latin and printed anonymously in the university town of Rinteln – was the first Catholic publication ever to denounce the witch trials and torture methods.

Spee's efforts were solitary during his lifetime, but not in vain. His Cautio Criminalis spread throughout Germany in copies and translations – despite being temporarily banned from the index. It opened the eyes of many educated contemporaries. In some regions, witches were no longer being burned by the second half of the century; Finally, in 1775, the Electorate of Cologne's Westphalia – to which the Paderborn region belonged – declared the use of torture illegal.

In the Paderborn region, the memory of Friedrich Spee lives on to this day. Right here, where pyres once burned, the man who denounced the madness of that time is honored. In Büren-Wewelsburg, a school bears his name – the Friedrich Spee School reminds new generations of his ideals every day. Schools in Paderborn, Rüthen, Trier, and elsewhere were also named after him, and at former execution sites, such as the Witches' Tower in Rüthen, monuments bearing Spee's image remind us of the crimes of the past.

Spee's life story still touches us because it shows how a single person can, with courage and morality, stand up to the overwhelming power of fear and fanaticism. His attitude – the unconditional respect for the human dignity of every individual and the fight against arbitrary violence – remains exemplary to this day.
Key Arguments of the "Cautio Criminalis"
Spee revealed in his book:

He exposed judicial torture – he showed that torture always leads to false confessions.
He criticized the trial procedures – he accused the defendants of contriving trials so that they could not be acquitted.
Condemned judges and inquisitors – he claimed many were motivated by greed (confiscation of property) and fanaticism.
He pointed out logical fallacies – if torture leads to new accusations, the persecution can never end.

Influence on the Cessation of Persecution
"Cautio Criminalis" had a significant but gradual impact:

Direct influence: The book prompted some German princes and judges to cease the trials.
Intellectual change: It contributed to the Enlightenment critique of superstition.
Legal reforms: It prompted a review of the use of torture in the justice system.
