Lecture I [R]

The second part [of logic], which classifies reasonings and determines their value, received from the eminent English logician, Hobbes, and from the great English philosopher, Locke, the very appropriate name critic.

At the outset, we define the principal purpose of logic to be to learn how to conduct any inquiry. [—]

In my opinion, the purpose of logic must ultimately come to be recognized as that of studying all that will be true of signs, or representations, independently of what particular signs have actually been created.

There will be three distinct divisions of logic which deal with different problems and have to be taken up successively. The first, which is that which simply performs the anatomy and histology of reasoning, may be called logical syntax. It has also been called speculative grammar.

…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.
