Book excerpt: Parmenides and the History of Dialectic is a study of Greek philosophical method as it affects contemporary philosophical issues. What was distinctive about the method of Parmenides, the inventor of philosophical argument as we know it? How did Parmenides' method affect Plato's dialectic, which was supposed to provide the solution to all ultimate philosophical problems? How, in turn, did Plato influence Hegel and our subsequent tradition?There are many studies of Parmenides' text, its philosophical content, and its influence. This study aims to do something different, to look at the form of the argument, the scope of its positive and negative language, the balanced structure its author generates, and the clear parallels with Plato's Parmenides.
