For a short period in the early 1700s a preponderance of the leading men of English science happened to be, or would soon become, members of one of the Freemasons lodges in and around London (Ninety-two were members of the Royal Society from 1720-1740 ['Freemasons who are or were Fellows of the Royal Society ...', paper prepared by Bruce B. Hogg (2009), for the Masonic Yearbook Historical Supplement ] ). Such was the strength of that bond of that truly committed caucus that they went on to found the Premier Grand Lodge and leave in perpetuity their scientific imperative upon it. No-one can be made a Freemason without professing a belief in a Supreme Being, but immediately he is admitted he is informed that the only way he may become a fit member of organised society (and particularly Freemasonry), is through education. On that day as a final recommendation he is told that he must study the Liberal Arts and Sciences and from this injunction there is no let-up throughout the whole of his ceremonial journey, including his progression through the Holy Royal Arch. Even after attaining the highest position possible he is informed that he is now considered to be a 'Master of the Liberal arts and Sciences' and in the Address to him he is told that it is henceforth his duty to instruct and guide his brethren. There is no better place to get to grips with this subject than to understand whence this instruction came and the '...the circumstances that led thereto'. This book explains in a precise, yet readable manner, the science which had an all pervading influence upon the Founders of the Premier Grand Lodge and why the ritual they adopted was necessarily predicated on contemporary science and why it is in all essentials, that which we practice today. It does so by first explaining that science, the Founders' involvement with it and then it puts into context their history, great strengths and weaknesses; their antecedence; contemporary politics and society and much else which caused Premier Grand Lodge style Freemasonry to thrive and become the amazing international success it is today.
