Abstract

This paper analyses different retrospective links between the scientia generalis by Leibniz and the three key traditions of the Renaissance and Early Modern Europe – the philosophical, the rhetorical and the encyclopaedic one. The issue demonstrates the insufficient charachter of the two influential interpretations of the idea of scientia generalis by Leibniz – as a project of elaborating a a method of mathematical calculations for non-mathematical subjects (L. Couturat, J. Mittelstraß, V. Peckhaus etc.) and as a project of an encyclopaedic synthesis combining ideas of the Lull’s Ars magna and humanistic rhetoric by M. Nizolius with the philosophical-theological encyclopaedism of J. Alsted and B. Keckermann (P. Rossi, W. Schmidt-Biggemann, T. Leinkauf etc.). The author presents the thesis that the formation of Leibniz’s idea of scientia generalis as well as some other concepts of the universal science in 17th century philosophy are the result of rethinking and expanding of the concept of the “first philosophy” delivered by Aristotle in his “Metaphysics”.
