This plan I therefore at once abandoned. But knowing that the jurisprudence of Masonry is founded, like all legal science, on abstract principles, which govern and control its entire system, I deemed it to be a better course to present these principles to my readers in an elementary and methodical treatise, and to develop from them those necessary deductions which reason and common sense would justify. Hence it is that I have presumed to call this work "The Principles of Masonic Law." It is not a code of enactments, nor a collection of statutes, nor yet a digest of opinions; but simply an elementary treatise, intended to enable every one who consults it, with competent judgment, and ordinary intelligence, to trace for himself the bearings of the law upon any question which he seeks to investigate, and to form, for himself, a correct opinion upon the merits of any particular case. Blackstone, whose method of teaching I have endeavored, although I confess "ab longo inter-vallo," to pursue, in speaking of what an academical expounder of the law should do, says: "He should consider his course as a general map of the law, marking out the shape of the country, its connections, and boundaries, its greater divisions, and principal cities; it is not his business to describe minutely the subordinate limits, or to fix the longitude and latitude of every inconsiderable hamlet." Such has been the rule that has governed me in the compilation of this work. But in delineating this "general map" of the Masonic Law, I have sought, if I may continue the metaphor, so to define boundaries, and to describe countries, as to give the inspector no difficulty in "locating" (to use an Americanism) any subordinate point. I have treated, it is true, of principles, but I have not altogether lost sight of cases. There are certain fundamental laws of the Institution, concerning which there never has been any dispute, and which have come down to us with all the sanctions of antiquity, and universal acceptation. In announcing these, I have not always thought it necessary to defend their justice, or to assign a reason for their enactment. The weight of unanimous authority has, in these instances, been deemed sufficient to entitle them to respect, and to obedience.
