Philosophers after Leibniz used a technical idiom to classify and explain the nature of mental content. Substantive philosophical claims were formulated in terms of this vocabulary, including claims about the nature of mental representations, concepts, unconscious mental content, and consciousness. Despite its importance, the origin and development of this vocabulary is insufficiently well understood. More specifically, interpreters have failed to recognize the existence of two distinct and influential versions of the post-Leibnizian idiom. These competing formulations used the same technical terms and taxonomic relations but assigned different connotations to those terms and employed different criteria for their application. This paper explains the two most influential versions of the post-Leibnizian idiom.
G.W. Leibniz’s legacy to philosophy is extraordinary for his vast body of work, for his originality and prescience, and for his influence. The aim of this volume is to provide a state-of-the-art exploration of Leibniz’s philosophy and its legacy, especially in the period up to Kant. The essays collected here offer new insights into signature elements of Leibniz’s thought – the theory of contingency, anti-materialism, the principle of sufficient reason, the metaphysics of substance, and his philosophy of mind – as well as the influence of predecessors such as Lull, Descartes, and Malebranche, the reckoning of his ideas in the works of Wolff and Kant, and the contributions of Clarke, Baumgarten, Meier, Du Châtelet, and others to the content, transmission, and reception of Leibnizian philosophy.
