"Most of the harm in the world is done by good people, and not by accident, lapse, or omission. It is the result of their deliberate actions, long persevered in, which they hold to be motivated by high ideals toward virtuous ends."

Algebra reverses the relative importance of the factors in ordinary language. It is essentially a written language, and it endeavors to exemplify in its written structures the patterns which it is its purpose to convey. The pattern of the marks on paper is a particular instance of the pattern to be conveyed to thought. The algebraic method is our best approach to the expression of necessity, by reason of its reduction of accident to the ghostlike character of the real variable.
