LEFT SIDE

In the symbolism of Freemasonry, the First Degree is represented by the left side, which is to indicate that as the left is the weaker part of the body, so is the Entered Apprentice's Degree the weakest part of Freemasonry. This doctrine, that the left is the weaker side of the body, is very ancient.

Plato says it arises from the fact that the right is more used; but Aristotle contends that the organs of the right side are by nature more powerful than those of the left.
