The second book concerns the powers of syllogisms. Aristotle shews, in twenty-seven chapters, how many different powerful arguments can be constructed from syllogisms, and what figures and modes are best adapted to each. He also gives suggestions both to the person prosecuting the argument, and to the one who defends.
