How Does Will Work?
A deep dive through Angel’s Trumpet into the machinery of consciousness
Angel’s Trumpet, or Brugmansia, is native to tropical South America. Its tissues contain tropane alkaloids, including scopolamine, that block muscarinic acetylcholine receptors. At sufficient exposure, the result can be a dangerous anticholinergic delirium marked by confusion, hallucinations, impaired attention, and severe disruption of memory.
In Ecuador, friend-of-a-friend stories circulate about strangers who blow powdered borrachero into someone’s face and then command the victim to empty a bank account, surrender a car, or help carry valuables out of their own home. The details blur into folklore, crime reporting, and myth. Scopolamine is not a dependable obedience drug. Delirium is messy and unpredictable. Still, the stories open a real and fascinating rabbit hole:
How can a chemical leave perception and movement partly online while weakening the capacity to form an intention, hold it in mind, and veto someone else’s?
The answer points toward a broader claim. Will is not a metaphysical switch hidden in one brain region. It is an activity the nervous system must keep constructing. Attention has to select a target. Memory has to preserve context. Salience has to assign value. A self-model has to register, I am the one doing this. Metacognition has to compare the current act with that model and interrupt the act when something is wrong.
Scopolamine is revealing because it attacks several of those operations at once.
