Study succinct but thorough enough to help the "young" mason to situate the ritual he practices within the great universal fraternity. This is not to claim exclusivity of the "authentic masonry," but to better identify the path that led to the fixing of the rite at the stage where he is currently interacting with other rites. The authors also make the effort to address the differences of opinion between "regular" and "adogmatic" between "spiritualists" and "positivist" without encouraging each to "excommunicate" other (or some other) . This booklet also highlights the complexity of the masonry, rightly recalling the "French" rite was actually started as a simple transposition, France, the English rite oldest ever known. Other British Brothers saw a dim abandonment of explicit references to religious traditions specifically Judeo-Christian, by this rite, while remaining resolutely spiritualist, claimed more strongly its universalism. So they founded a new rite they called "ancient", reserving with disdain, the "modern" qualifier to that other rite that was actually older than theirs. The "Modern French Rite" could just as well be called "old anglai rite." The rite mainly practiced by the English Masons, the rite "emulation", this is actually a hybrid between the rite "modern" (in fact old), and the "old" rite (actually better) . This booklet gives up some information that the lambda brother collected here and there, without much coherence. The last chapter, devoted to "high grades" is against a bit obscure ... especially for a normal brother who is not yet at this stage. This confirms that masonry, practice is more important than reading, which makes sense only if it accompanies practice.
