This is an excerpt from the book Extraordinary Popular Delusions and the Madness of Crowds by Charles Mackay. He wrote this book in 1841, almost 200 years ago. Based on the excerpt, the title more or less says it all. The book, which has a slightly catalog-esque feel to it, describes a number of cases where a person, usually a woman or a girl, was accused of being a witch. It also gives you a brief history of witch hunts - from its peak in the beginning of the 17th century to the end in the late 18th century (although in some countries people still believe in witches).
It is entertaining in - a macabre kind of way – to read about the witch trials. Although I have read a fair amount about witches, I am still amazed every time I read about the trials. Witness accounts in which someone claimed to have seen a cat that looked like the accused were taken seriously. Experts claimed that if you talk at loud to yourself then you are definitively possessed by a demon and must, therefore, be a witch. I am guessing that to some extent the witch hunts were a way to satisfy the crowd's lust for blood and their desire for vengeance over the extreme hardships in their life. We should keep this in mind today when people on social media seem to think that they are better jurors than the people working within the judicial system.
If you want a brief introduction to the history of the witch-hunt, with a European bias, then this book is a good buy. However, you can get more detailed accounts (remember that this is an excerpt) and while the book has a Sam Harris feel to it, only small parts of it were actually authored by him.
