"We must renounce attempts at building an absolute revolutionary strategy out of the elements of our limited experience of the three years of civil war, during which units of a particular quality fought under particular conditions. Clausewitz warned very well against this. "What could be more natural," he wrote, "than the fact that war of the French Revolution had its characteristic style, and what theory could have been expected to accommodate it? The danger is that this kind of style, developed out of a single case, can easily outlive the situation that gave rise to it: for conditions change imperceptibly. That danger is the very thing a theory should prevent by lucid, rational criticism. In 1806 the Prussian generals were under the sway of this methodism", and so on. Alas! Prussian generals are not the only ones with an inclination towards methodism, that is, towards stereotypes and conventional patterns."
