Peterson's syllogisms; Peterson's rules; Peterson's square of opposition; Peterson's rules based on grades

In this publication we will focus on the presentation of several methods by which we are able to verify the validity of generalized Peterson syllogisms. We will focus on a special group of so-called non-trivial syllogisms when a generalized intermediate quantifier is considered in both premises, e.g. Most, Several, Many, etc.
