This paper provides a new system of logic, including philosophical principles and logical notation, based on the work in logic done by Aristotle and later by Ayn Rand but also with a nod to modern Analytical philosophy, which is extremely useful to lawyers for analyzing facts to determine whether they satisfy the elements of a claim, as well as organizing arguments to a jury and presenting evidence. A libertarian politics emerges from the system of logic as a byproduct of the logical analysis of the intersection of law, politics, and philosophy. Required reading for lawyers and citizens who want to understand the law and how and why it impacts them.
