Veritas sequitur esse

In the article the fact was emphasised that the question about the truth, about its source and mode of existence, appeared at the times of ancient Greeks along with the question about being. For this reason studies on both being and truth are metaphysics’ task of outstanding importance. This is because truth means ..that which is real", and Greeks defined as real ..that which always is and knows no birth or death” . Ancient philosophers defined this kind of considerations as „giants’ struggles” , that is, as great and difficult undertakings. With time these studies assumed the shape of a controversy that mainly consisted in connecting or disconnecting truth from being. In order to settle this controversy and to declare oneself for one of the solutions one has to consider the whole context in which the problem of truth appeared, as from the historical perspective one can see better originality and at the same time soundness of one of the most interesting solutions of the controversy that appeared in the 13lh century and was formulated as the short sentence: „veritas sequitur esse rei” - „truth is the consequence of the existence of things”. This solution did not appear as deus e x machina but it followed the whole experience and tradition of ancient and medieval philosophy. In the context of this experience Thomas Aquina s ’ solution may be properly understood and accepted along with its consequences - both theoretical and practical - that it involves.
