FORE:"I thought I could rely upon you," she said gratefully. "Mr. Isidore, you have taken a great load from my mind."It is evident, then, that Aristotle cannot be approached with the same perfect dispassionateness as the other great thinkers of antiquity. He is, if not a living force, still a force which must be reckoned with in contemporary controversy. His admirers persist in making an authority of him, or at least of quoting him in behalf of their own favourite convictions. We are, therefore, bound to sift his claims with a severity which would not be altogether gracious in a purely historical review. At the same time it is hoped that historical justice will not lose, but gain, by such a procedure. We shall be the better able to understand what Aristotle was, after first showing what he neither was nor could be. And the utility of our investigations will be still further enhanced if we can show that he represents a fixed type regularly recurring in the revolutions of thought.

FORE:In ages past, various attempts were made to find some constant in nature on which measures could be based. Some of these attempts were ludicrous, and all of them failures, until the vibrations of a pendulum connected length and space with time. The problem was then more easy. The changes of seasons and the movement of heavenly bodies had established measures of time, so that days, hours, and minutes became constants, proved and maintained by the unerring laws of nature.
