Law, Lies and Logic
The foundations of logical science, and of that part of law which concerns itself with logic rather than rhetoric, were laid by Aristotle
, in 350 B.C.E.
His analysis of reasoning with demonstrable facts, as against appeals to "reason", came in a golden age of rhetoric. He noted that the tools of rhetoric had not been built from an analysis of how language is used, but had been built piecemeal. He, on the other hand, built his tools of logic from an observational foundation.
