Now, it is obvious that the infliction of “an acute infectious disease,” deliberately and extensively, on the human body, is a vicious and dangerous practice, per se and prima facie, and cannot be continued indefinitely without serious injuries, as I have already proved, and hence Dr. Rosenau contradicts himself at the very outset in his statement or apology for vaccination. In his next phrase he makes the still more surprising statement that this inflicted disease is “_always mild and trivial_,” which assertion is undoubtedly a falsehood! And Dr. Rosenau must know as well as any doctor or layman in this country that this assertion is false, and per contra that this inflicted disease--vaccination--is sometimes very severe and fatal and far worse than natural smallpox itself, and that it often causes more annual deaths than smallpox, as I have already proved by overwhelming evidence and by the highest statistical records in the world! I would, therefore, here respectfully suggest that Dr. Rosenau make some apology to his readers for this falsehood or mistake, and correct this statement as soon as possible in the next edition of his book. To emphasize and dispose of this serious error of Dr. Rosenau I will now show out of his own mouth how he stultifies and contradicts himself, and logically admits that vaccination is not “always mild and trivial,” but is often quite dangerous and fatal. For example, he says: “And although the disease is always mild and trivial, yet it must not be treated as trifling.” This phrase, just quoted, is, surely, a rich verbal and logical study of medical sophistry and equivocation. Vaccination, this medical champion tells us, is always a “trivial” disease, but it is not a “trifling” disease. This is morally and logically equivalent to telling us that vaccination _is trivial_ and it _is not trivial_! In other words, he asserts in one breath what he denies in the next, or contradicts himself in successive breaths! This is so, because the dictionaries show that the two words “trifling” and “trivial” have exactly the same meaning and are synonymous and identical, so that “trivial” is defined as “trifling,” and “trifling” is defined as “trivial.” This, therefore, morally and logically, means a confession out of his own mouth that the inflicted disease, vaccination, is not always either trivial or trifling, but is often very dangerous and deadly, which is, of course, the exact and demonstrable truth, and the scholarly Dr. Rosenau is the last man who can plead ignorance of this truth. Indeed, in another paragraph of his contradictory statement, he absolutely acknowledges this serious danger of vaccination while apparently trying to conceal or deny it. For example, he makes this conclusive and crushing admission that: “While the aggregate number of deaths resulting from the complications of vaccination may be considerable, the aggregate of the individual risk is so small as to be disregarded.”
