One cannot help being amazed at the cool impudence with which infidels take for granted the very points to be proved, and set aside, as unworthy of serious examination, the most authentic records of history and facts of science. When skeptics, who are determined not to believe in the Bible, find the historical evidences of its genuineness, authority and inspiration impossible to be overthrown by ridicule or sophistry, they turn their attention to some other mode of attack; and, of {38} late years, they have ransacked the whole circle of sciences hoping to find a more powerful weapon. Especially has every new discovery been hailed by skeptics as an ally to their cause, until further acquaintance has proved that it was not so. Thus, when geology began to upheave its titanic form it was eagerly greeted by skeptics; but now that they have discovered the proofs it gives of a Creator they are getting shy of its acquaintance. It is, therefore, worth while to enquire, is science really so positive as these persons pretend? Or, is it true that the students of the physical sciences have no certain knowledge of their theories? We need not here speak of the disputes between Herschel and Ferguson, Newton and Brewster, La Place and Lionville. Rather let us begin with the most positive of all sciences. _Mathematics_--the science of magnitude and numbers--and note a few things concerning it. Upon reflection, it is surprising how few subjects are capable of a mathematical demonstration. The mathematician may demonstrate the size and properties of a triangle, but he cannot demonstrate the continuance of any actual triangle for one hour, or one minute after his demonstration.
