This document discusses and distinguishes between arguments and non-arguments, and outlines key elements of arguments including premises, conclusions, and common argument structures. It defines an argument as a claim defended with reasons, composed of one or more premises and a conclusion.

Common patterns of deductive reasoning like categorical syllogisms and elimination arguments are described.
