What he did love about this war was seeing theory put into practice. The life of the mind is a wonderful thing, but you don’t really know if a plan is any good when it’s still in your head, do you? You only have to read all of those vain treatises by long-ago rulers to know that self deception is one of the most common vices of Men. The only way to tell if your ideas are any good is to take them out and field test them.
