Square and Compasses (Symbol Of Freemasonry)

The Square and Compasses is the single most identifiable symbol of Freemasonry. Both the square and compasses are architect's tools, and are used in Masonic ritual as emblems to teach symbolic lessons.
Some Lodges and rituals explain these symbols as lessons in conduct: for example, that Masons should "square their actions by the square of virtue" and learn to "circumscribe their desires and keep their passions within due bounds toward all mankind". However, as Freemasonry is non-dogmatic, there is no general interpretation for these symbols that is used by Freemasonry as a whole.
Thus some take the Letter 'G' to represent Goodness, the essential goodness of Freemasonry and of humankind. Others argue that the letter 'G' stands for Geometry the basis of the operative craft that gave birth to modern Freemasonry.
