Logic, though the other exact science, has not had the sort of assailants who have clustered about mathematics. There is a sect which disputes the utility of logic, but there are no special points, like the quadrature of the circle, which excite dispute among those who admit other things. The old story about Aristotle having one logic to trammel us, and Bacon another to set us free—always laughed at by those who really knew either Aristotle or Bacon—now begins to be understood by a large section of the 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.”
