The answer to this question takes us back through history when men built the great Gothic cathedrals and other buildings out of fine grained sandstone or limestone (which by reason of its adaptability was called “Freestone”). The workers were then known as “Freestone Masons” and this was eventually changed to “Freemasons”.
Additionally, a requirement for entrance into the craft was the candidate to be a man, neither a bondsman nor the son of a bondswoman. This meant freedom to travel and work without limitation, which naturally would lead to freedom of mind and spirit.
Freedom of thought and expression is one of our most prized possessions. There are external truths which we may contemplate. Yet no two men think exactly alike. No two minds grasp an idea with identical results. This, we cherish our beliefs and give our Fellow-man the right to his beliefs.
