Fully agree. I would add that besides economics there is another thing that should be taught as soon as possible: logic. Now, reading Elementary lessons in logic, I blame myself for not studying it back in school, as I began to realize how stupid it is to teach mathematics and do not even explain basic rules of logic.
An excerpt from the Preface:
IN preparing these Lessons I have attempted to show that Logic, even in its traditional form, can be made a highly useful subject of study, and a powerful means of mental exercise. \Vith this view I have avoided the use of superfluous technical terms, and have abstained from entering into questions of a purely speculative or metaphysical character. For the puerile illustrations too often found in works on Logic I have generally substituted exalnples drawn from the distinct objects and ideas treated in the natural and experimental sciences; and in this and other respects have aimed at rendering these Lessons a suitable companion to a series of science schoolbooks.
Logic is not only an exact science, but is the most simple and elementary of all sciences; it ought therefore undoubtedly to find some place in every course of education. The relations of propositions and the forms of argument present as precise a subject of instruction and as vigorous an exercise of thought, as the properties of geometrical figures, or the rules of Algebra. Yet every school-boy is made to learn mathematical problems which he will never employ in after life, and is left in total ignorance o£ those simple principles and forms of reasoning whichwill’ enter into the thoughts of every hour. . Logic should· no longer be considered an elegant and learned accomplishment; it should take its place as an indispensable study for every well-informed person.
