Hey, remember when we said the guy was a physician? Yeah, he was treating people this whole time. This is another reason why if you got sick in the 1500s, you were probably better off just staying home and rolling the dice.
Duncan MacDougall Could Guess Your Soul's Weight
Duncan MacDougall is one of the shadiest sounding doctors we've ever come across, and seems like the kind of guy who liked to play games like "Drink This Bubbling Liquid" and "Smell my Ether Soaked Rag," both of which we learned were unfun after playing a couple rounds with the man who sold bikes around the corner.
In the early 20th century, MacDougall theorized that the soul had weight. His experiments even came up with a number, 21 grams, which is where the title of that movie came from. What experiments you ask? The experiments where MacDougall took six patients "in the process of dying" and weighed them.
Being a profound scientific mind, there's not much written about who these people were or why and how they were dying. It's just enough to know that in their last moments, probably while they were hoping for a miracle, or maybe CPR, they were getting rolled onto a scale like deli-sliced meat at the market.
MacDougall also took the time to replicate his experiments with dogs. Fifteen dogs, in fact, which were apparently uncooperative when it came to dying of natural causes, so he had to help them along towards doggy heaven.
Although, according to his experiment, while humans lost anywhere from no weight because they died too quick for him to adjust his scale to several ounces at death, dogs lost nothing and therefore have no souls, which by our calculations means Guthrie's two-headed dog had twice as much no soul as a regular dog and was therefore evil to the core.
