"I considered it necessary and important for my scientific research activity to achieve a work of synthesis of the most significant studies and articles published, by means of which I tried to make known the contributions of two thinkers in the history of the Romanian and universal philosophy, and the above presentation shows my epistemic curiosity and passion for exploring the works of the two thinkers, in various scientific events, held in a long period of time. Furthermore, the presentation of the texts within this volume both in Romanian and English offers a real opportunity to disseminate the scientific research results dedicated to G.W. Leibniz and Dimitrie Cantemir, both in the Romanian and universal cultural area, at international level." Author
