Why do brethren consider that the outer form of Freemasonry is its most important aspect?
What does it matter what its modern name is when the essence is so largely ignored.
Here is Albert Mackey:
"But he who expects to arrive at a satisfactory solution of this inquiry must first—as a preliminary absolutely necessary to success—release himself from the influence of an error into which novices in Masonic philosophy are too apt to fall. He must not confound the doctrine of Freemasonry with its outward and extrinsic form. He must not suppose that certain usages and ceremonies, which exist at this day, but which, even now, are subject to extensive variations in different countries, constitute the sum and substance of Freemasonry. .. But it must be always remembered that the ceremony is not the substance. It is but the outer garment which covers and perhaps adorns it, as clothing does the human figure. ...And so take from Masonry these external ceremonies, and you still have remaining its philosophy and science. These have, of course, always continued the same, while the ceremonies have varied in different ages, and still vary in different countries" The Symbolism of Freemasonry
If Mackey is correct then tracking the outer format of Freemasonry is of little value. Equally tracking the ritual back through history does not add much value.
So what is the philosophy and science of Freemasonry that has remained unchanged over the ages?
