“The bayonet is not a chemical agent the mere possession of it will not make men one whit more intrepid than they are by nature. Nor will any amount of bayonet training have such an effect. All that may be said of such training is that, like the old Butts Manual, its values derive only from the physical exercise. It conditions the mind only in the degree that it hardens the muscles and improves health.The bayonet needs now to be re-evaluated by our Army solely on what it represents as an instrument for killing and protection.

“There has always been a temptation to classify economic goods in clearly defined groups, about which a number of short and sharp propositions could be made, to gratify at once the student’s desire for logical precision, and the popular liking for dogmas that have the air of being profound and are yet easily handled. But great mischief seems to have been done by yielding to this temptation, and drawing broad artificial lines of division where Nature has made none. The more simple and absolute an economic doctrine is, the greater will be the confusion which it brings into attempts to apply economic doctrines to practice, if the dividing lines to which it refers cannot be found in real life. There is not in real life a clear line of division between things that are and are not Capital, or that are and are not Necessaries, or again between labour that is and is not Productive.”

“(1) Use mathematics as shorthand language, rather than as an engine of inquiry. (2) Keep to them till you have done. (3) Translate into English. (4) Then illustrate by examples that are important in real life (5) Burn the mathematics. (6) If you can’t succeed in 4, burn 3. This I do often.”
