11 What We have said, and are about to say, must be understood of the sect of the Freemasons taken generically, and in so far as it comprises the associations kindred to it and confederated with it, but not of the individual members of them. There may be persons amongst these, and not a few who, although not free from the guilt of having entangled themselves in such associations, yet are neither themselves partners in their criminal acts nor aware of the ultimate object which they are endeavoring to attain. In the same way, some of the affiliated societies, perhaps, by no means approve of the extreme conclusions which they would, if consistent, embrace as necessarily following from their common principles, did not their very foulness strike them with horror. Some of these, again, are led by circumstances of times and places either to aim at smaller things than the others usually attempt or than they themselves would wish to attempt. They are not, however, for this reason, to be reckoned as alien to the masonic federation; for the masonic federation is to be judged not so much by the things which it has done, or brought to completion, as by the sum of its pronounced opinions.
