This work analyses four formulations of syllogistic with negative terms. The first one is a well-known formulation of the system given by Anders Wedberg. The second formulation is a simplification of the axiomatics of Wedberg’s system given by Bogusław Iwanuś. The author of the third formulation is Albert Menne. In the article, a simplification of the axiomatics of Menne’s system is proposed. It is here regarded as the fourth formulation of syllogistic with negative terms. Logical connections between these constructions are examined.
