Logic, Mathematics or Metaphysics: and Yet, is the Leibniz’ Conception Enough Well-Grounded?

Whether Leibniz was a metaphysicist or a dogmatic philosopher? We argue that S. Secundant in his book 1) convincingly proved that the epistemology of Leibniz played a leading role in relation to his metaphysics; 2) described in detail its critical foundation. The significant scientific achievement of S. Secunant is the analysis of the differences in the grounds of Leibniz’ epistemology and Kant's critique, as well as evidence of a more profound nature of the tasks and normative bases the first of them.
