Why is distilled alcohol referred to as spirits?
im not 100% on this but ive heard that in midieval days people
believed that when a man was drunk and disorderly or mean that evil
spirits had entered him thru the drink so it could have to do with
that. Alcohol brings out the spirit(The inner beliefs and morality
that guide that particular individual) that is most prominent in us
while reducing our inhibition(wall) that is a defensive mechanism
clouding our true self.
