A few days later, through the columns of the same paper,[649] Morse replied at greater length to the criticisms which “An American” had brought to public attention. That he had not “too hastily recommended Professor Robison’s late work” Morse regards as sufficiently demonstrated by the fact that he had had a copy of the book in his possession since the middle of the previous April. This he had examined with care, and he had satisfied himself that it was entitled to the recommendation he had given it in his fast day sermon. So far as the hostile criticism of the authors of _The Critical Review_ is concerned, he has no doubt that their _caricature_ of Robison’s book is to be construed as expressive of their determination to destroy its reputation and thus prevent its circulation, since it probably exposed and thwarted their favorite schemes. Besides, over against the contemptuous estimate that the authors of _The Critical Review_ had seen fit to place upon Robison’s volume, Morse was able to oppose a very different judgment. _The London Review_ of January, 1798, extracts from which he was glad to be permitted to offer in evidence,[650] placed an estimate upon Robison’s book which was both accurate and just. From this “An American” will be able to gather that “‘the Doctors in Europe and America’” do not “differ so widely in their estimation” of the importance of Robison’s volume as had been asserted. The observations that Morse is now offering to the public, it is his expectation, will serve to effect his personal justification; but if doubts still remain in the minds of any, he can only recommend as the best and perhaps the only sure means of dissolving them that such persons read _Proofs of a Conspiracy_ for themselves.[651] With respect to the inception of the Illuminati agitation in New England, the utterances of two other clergymen require attention. One of these, the Reverend David Tappan, professor of divinity at Harvard, in a discourse[652] delivered before the senior class of that institution on the 19th of June, 1798, cautioned the young people before him who were about to quit the life of the college to guard against the dangers of speculative principles, the pleasures of idleness and vicious indulgence, the degrading tendency of selfish sentiments, _and_ “a more recent system, which ... has for its ostensible object THE REGENERATION OF AN OPPRESSED WORLD TO THE BLISSFUL ENJOYMENT OF EQUAL LIBERTY.” This “more recent system,” Tappan explained, was the philosophy of the Order of the Illuminati.[653]
