Leibniz and Leibnizianisms The present is pregnant with the future, the future can be read in the past, the remote is expressed in the next,” remarks Leibniz in his Principles of Nature and Grace Founded in Reason. Reported first to our reading, then to our current understanding of Leibniz, this statement so characteristic of his writing even us, readers and successors, incites us, readers and successors, to formulate and reformulate a multitude of questions about the whole "future past" of thought. Leibnizian: to read in its present and to give its future. Is there something like Leibnizianism? Does the very nature of Leibniz's thought allow it?

Currently, several Leibnizian societies are engaged in the laborious task of elucidating the legacy of the Hanoverian philosopher. Where are we today in understanding Leibniz's legacy and Leibnizianism(s)?
