The paper draws on the theory of universals involved in scholastic logic in Lithuania in the 16th century. The author focuses on the ontological and epistemological levels of the theory. Namely, interpretations of the nature of the universals and its relation to human cognition are scrutinized. The author comes to a conclusion that the ontological level of the above theory cannot be strictly attributed to any classical variant of realism or nominalism. Similarly to the position of Francisco Suarez, it would rather be regarded as an intermediate model between moderate realism and conceptualism. As for the epistemological level of the theory, it varies from Thomistic to Ockhamistic.

Keywords: universal, objective being in intellect, logic in the old Vilnius University
