In Freemasonry, there are 2 forms of ashlars.
Rough Ashlar
In operative Freemasonry, the rough ashlar represents a rough, unprepared or undressed stone. In speculative Freemasonry, a rough ashlar is an allegory to the uninitiated Freemason prior to his discovering enlightenment.
Perfect Ashlar
Operatively, the Perfect ashlar represents the dressed stone (after it has been made uniform and smoothed) by use of the working tools, the common gavel, (mallet) and chisel. (The chisel may be found in English Freemasonry, but is not used in the United States as a Freemason symbol).
Only after the stone has been dressed by an experienced stonemason, can it be suitable to be placed into the architectural structure or building.
Speculatively, a Perfect Ashlar is an allegory to a Freemason who, through Masonic education, works to achieve an upstanding life and diligently strives to obtain enlightenment.
Rough and Perfect Ashlars
In the Fellowcraft Degree, we see the use of the Rough and Perfect Ashlars. The lesson to be learned is that by means of education and the acquirement of knowledge, a man improves the state of his spiritual and moral being.
Like man, each Rough Ashlar begins as an imperfect stone. With education, cultivation and brotherly love, man is shaped into a being which has been tried by the square of virtue and encircled by the compasses of his boundaries, given to us by our Creator.
Rough and Perfect Ashlar: Fitted For The Builder's Use
In ancient times, quarried stone which could be easily shaped into desired configurations, was called "freestone". Typical freestones are limestone and sandstone.
Then, as now, only after refining and smoothing these rough stones into their desired shape, were the stonemasons able to "fit them for the builder's use".
In the Fellowcraft degree, the Rough Ashlar represents a man's unrefined state and his need for improvement. He learns that the goal of being a better man includes spirituality of thought and striving for perfection of conduct. Via duties, expectations and obligations, he is charged to work toward these goals of self improvement.
As the Freemason "smoothes" his rough edges, internally and externally; he becomes a better man and, therefore, a better Freemason.
Once a man has perfected his ashlar to the best of his ability,... as Brothers to all mankind, it is his duty to help others become better men and better Freemasons.
Rough and Perfect Ashlar - The Potential For Change
All rough ashlars must have within them the potential to be made into a perfect ashlar.
The stone must be made of sound material and have a minimum of character flaws which may cause it to weaken the edifice (building). It must be capable of being worked into a perfect stone. This is why candidates for the degrees are asked many questions as to their qualifications and character about why they wish to become Freemasons.
The candidate must have the potential to both serve and support the Fraternity. He must be carefully inspected, just as each Rough Ashlar is inspected for quality in order to be able to "fit" him into Freemasonry's tenets and goals, which are compatible to God's laws.
An imperfect stone may be made perfect, however major flaws are difficult to overcome and when assembled into a structure, the entire structure can be weakened from its improper use. This is as true of men as it is of stones.
Rough and Perfect Ashlar - States of Metamorphose
Freemasonry has a glorious history. Flawed ashlars can bring negative feelings and reproach upon the Fraternity from non-Freemasons in the outside world and therefore, can have no place within its walls.
...That said,...let us not forget that perfect ashlars are not found lying about the stone quarry without benefit of their having been hammered, chiseled and polished into such a state of being.
It also holds true that "perfect" men are also such an anomaly without the benefit of brotherly love, guidance and light. There are very few Freemasons who have not been in both the rough and perfect ashlar state-of-being at some point in their lives.
Freemason Duties For the Future of the Craft
1. Freemasons must give serious consideration to our personal responsibility to educate other Brothers toward their self improvement.
Like the Good Samaritan in the Holy Books; it is in the giving and assistance to others in which you will find the true "jewels" of enlightenment. True Master Masons not only exemplify the tenets of the craft, but they teach what they learn.
2. Lodges should carefully judge the potential of each candidate, weighing both their character and their potential for change.
3. Each Freemason is charged to extend the hand of brotherly love and affection to help new Freemasons become better men and strive to live on the square, stand upright with the plumb and take their true place as a man who would make his Creator (the Almighty), proud of him.
The lesson of the Rough and Perfect Ashlar applies to all men who are worthy,...who have a heartfelt wish to go from ignorance to knowledge,...from darkness to light...
