No real knowledge is sterile. Even so elementary an operation as that of abstracting from the particular configuration of the triangles or other figures, and the relative situation of the particular lines or points, in the diagram which aids the apprehension of a common geometrical demonstration, is a very useful, and far from being always an easy, exercise of the faculty of generalization so strangely imagined to have no place or part in the processes of mathematics.

They develop and implement improved ways to extract, process, and use raw materials, such as petroleum and natural gas. I contend, therefore, that even without reference to its applications mathematics in the high schools has a value equal to that of the other subjects of instruction. Nor is it a short experience that can instruct us in that practical science, because the real effects of moral causes are not always immediate.
