…the third branch of logic which specially considers how inquiries are to be ordered and arranged is by Plato and Aristotle and all their followers, and by English logicians generally, called Method. But in order to distinguish this from the concrete and more usual meaning of the same word method, I prefer to call it Methodeutic. The German logicians call it methodology; but methodeutic is a better word from every point of view.
