you seen _this_, Sir! In reply, I recommended him to show it to my friend
Mr.----, for whom he had published mathematics. Educated men, used to books
and to the converse of learned men, look with mysterious wonder on such
productions as this: for which reason I have made a quotation which many
will judge had better have been omitted. But it would have been an
imposition on the public if I were, omitting this and some other uses of
the Bible and Common Prayer, to pretend that I had given a true picture of
my school.

educated world. The author of this tract connects the old logic with the
indecencies of the classical writers, and the new with moral purity: he
appeals to women, who, "when they see plainly the demoralizing tendency of
syllogistic logic, they will no doubt exert their powerful influence
against it, and support the Baconian method." This is the only work against
logic which I can introduce, but it is a rare one, I mean in contents. I
quote the author's idea of a syllogism:

"The basis of this system is the syllogism. This is a form of couching the
substance of your argument or investigation into one short line or
sentence--then corroborating or supporting it in another, and drawing your
conclusion or proof in a third."

On this definition he gives an example, as follows: "Every sin deserves
death," the substance of the "argument or investigation." Then comes,
