Freemasonry is a fraternal organisation that arose from the loose organization of medieval masons (i.e. stone workers) working in the medieval building industry (i.e. craft workers involved in medieval stone work).[1] Early organizational forms included "lodges," incorporations, and craft guilds.[2] Early Freemasonry based on craft labour is known as Operative Freemasonry.
This book is a decent and concise insight into the real teachings of Freemasonry, it puts aside all the Christian dogma of which other books about the topic are full of, and brings upfront the more pragmatic implications of "mental science".
