From Ignorance to Knowledge
bingo.
we actually break it into three steps:
Ignorance, Knowledge, then Wisdom.
If you look at the pillars of the lodge: Beauty, Strength, and Wisdom, they are very much represented by the JW, SW, and WM, and also by the 3 degrees.
Ignorance is Bliss.
Knowledge is Strength.
Experience is Wisdom.
Plum, Level, and Square. They are the symbols belonging to the wardens and are representative of the 3 stages of light and Freemasonry. The manner of reception into the lodge is also representative of the 3 stages of light (a) Learn how to control yourself, b) apply that knowledge, c) master that knowledge).
But there you go, that's only my interpretation after light* study and contemplation of the degrees. Of course, everyone interprets it for themselves, and either way, this is in no way an exhaustive explanation of how I see it.
*not the "masonic" light, but the "i didn't study very hard" kind of "light study"
