Mathematics has stood as a bridge between the Humanities and the Sciences since the days of classical antiquity. For Plato, mathematics was evidence of Being in the midst of Becoming, garden variety evidence apparent even to small children and the unphilosophical, and therefore of the highest educational significance. In the great central similes of The Republic it is the touchstone ofintelligibility for discourse, and in the Timaeus it provides in an oddly literal sense the framework of nature, insuring the intelligibility ofthe material world. For Descartes, mathematical ideas had a clarity and distinctness akin to the idea of God, as the fifth of the Meditations makes especially clear. Cartesian mathematicals are constructions as well as objects envisioned by the soul; in the Principles, the work ofthe physicist who provides a quantified account ofthe machines of nature hovers between description and constitution. For Kant, mathematics reveals the possibility of universal and necessary knowledge that is neither the logical unpacking ofconcepts nor the record of perceptual experience. In the Critique ofPure Reason, mathematics is one of the transcendental instruments the human mind uses to apprehend nature, and by apprehending to construct it under the universal and necessary lawsofNewtonian mechanics.

Dieser Band fuhrt 16 Aufsatze von Herbert Breger zusammen, die um Leibniz' Arbeiten zur Mathematik und Physik und ihre philosophischen Voraussetzungen kreisen. Drei interessante und ungewoehnliche Aspekte stehen hierbei im Vordergrund: Kontinuum, Analysis und Informales. Leibniz' Kontinuum und seine Analysis sind gerade wegen ihres Unterschieds zur heutigen Mathematik interessant. Anhand zahlreicher Beispiele wird ferner die Frage nach dem Verhaltnis zwischen der mathematischen Rationalitat und der Kunst gestellt und die nach den engen Beziehungen zwischen Mathematik und Philosophie bei Leibniz eroertert. Es wird gezeigt, dass der Leibniz zugeschriebene Brief zum Prinzip der kleinsten Wirkung, der Anlass zu einem Streit zwischen Maupertuis, Samuel Koenig und Voltaire wurde, eine Falschung war. Das Buch erscheint im Leibniz-Jahr 2016, in dem auch der X. Leibniz-Kongress stattfindet.
