A brief history of logic: Aristotle and deduction | Math Foundations 251 | NJ Wildberger

In this video we begin to examine the history of logic from its early beginnings in ancient Greece, with the work of Parmenides, Zeno, Plato and then Aristotle. It was Aristotle who almost single handedly set out the modern theory of logic as it was to be for two thousand years until the modern European era.

Aristotle is concerned with correct logical inference based on what are called syllogisms, and these have been categorized, and given amusing names by later writers. His aim was to strengthen dialectics, to assure correct deductions in arguments, and for logic to be an educational vehicle.

My blog is at http://njwildberger.com/, where I will discuss lots of foundational issues, along with other things.

Online courses are being developed at openlearning.com. The first one, already underway, is Algebraic Calculus One at https://www.openlearning.com/courses/... Please join us for an exciting new approach to one of mathematics' most important subjects!
