About Friedrich Spee
Friedrich Spee was a German Jesuit priest, professor, and poet, most well known as a forceful opponent of witch trials and one who was an insider writing from the epicenter of the European witch-phobia. Spee argued strongly against the use of torture, and as an eyewitness he gathered a book full of details regarding its cruelty and unreliability. He wrote, "Torture has the power to create witches where none exist."
