**2. Dialectics**

Dialectics appeared in Ancient Greece as a discourse between two or more people holding di fferent points of view about a subject, but wishing to establish the truth through reasoned arguments. Formal logic—developed later—refers to subjects concerned with the most general laws of truth. This means that dialectics refers to the world consisting of multiple acting subjects, while formal logic refers to a unified sub-set of the laws common to all observers.
