Leibniz Symposium of Japan

Leibniz (1646-1716) was one of the greatest savants in 17th century. He contributed to various fields of human knowledge, such as mathematics, natural sciences, logic, ethics, jurisprudence, linguistics as well as philosophy. His achievement in each of these fields still keeps remarkable influence.
The typical feature of Leibniz's way of thinking can be seen in his preference for harmonization and reconciliation between opposite theories. In order to realize this harmonization, Leibniz tries to understand and appreciate each theory without prejudice. Interestingly, such a harmonization is arranged by his own philosophy, whose essence consists , in a sense, in a principle of harmonie péétablie among different theories or different fields. From this point of view, it is obvious that to have deep understanding of his way of thinking, it is necessary to focus attention on his philosophical theories.
To promote the study on Leibniz we organized Leibniz Symposium. This society is supported by Japanese Centre for Ontology Research(JCOR). We have held annual conference since 2007(at Keio University for the 1st time on March in 2007, at Gakushuin University for the 2nd time on March in 2008, and at Kobe University for 3rd time on March in 2009).
Besides annual conference , we are plannnig to have seminers several times a year, which will offer time for careful reading and analysis of philosohical text of Leibniz. In each seminer we are due to have a little long-haul presentations by members in small-group and discussions. For the rest, we have mini seminars as needed.
This website 'Leibniz Symposium of Japan' has been launched on April 2009, supported by the Promotion Foundation of Learning in Keio University since 2009. This website provides the cutting-edge informaiton about the research of Leibniz in Japan : 1) some of papers presented in our conferences or workshops, 2) the Chronology of Leibniz (thanks to Professor Yuji Matsuo’s cooperation) .



leibnizpl.jpg G.W.Leibniz(1646-1716) was born in Leipzig near the end of the Thirty Years’ War (1618–1648) which was one of the most destructive conflicts in European history.
He contributed to various fields of human knowledge, such as mathematics, natural sciences, logic, ethics, jurisprudence, linguistics as well as philosophy. The discovery of precalculs(1675) as an achievement on matematics, the revive of the concept of dynamic in physics, and a divisal of Universal Characteristic in logic are widely known. It is interesting that all his achievements are not independent of each other. Such a characteristic becomes much more clear when we see Leibniz’s Chronology.
>>>See Leibniz’s Chronology
Leibniz always addressed various issues in different fields concurrently. His highly-diverse activities are attributed to his creativity to relate different ideas to each other in parallel. He harmonizes these ideas into a simple principle common to them.
Leibniz's philosophy seems to play a central part in this harmonization. As regard to his philosophy, however, Theodicy is the one and only one published volumious work in his lifetime, so his philosophy has yet to appear in full view(the complete work is in course of publication). This is the just beginning of the eclaicissment of his philosophy.

My Interest : L'originalité des principes et des concepts leibniziens,à savoir le système de l'harmonie préétablie,le principe du meilleur à l'origine de l'optimisme, le principe de raison suffisante, l'idée d'individualité et celle d’inquiétude, ne cesse de surprendre, exaspérant les uns, inspirant les autres, par l'invention dont elle procède. Ne laissant pas indifférent, de tels principes et concepts suscitent, par un jeu de convergences, de multiples interprétations, parmi lesquelles j’étudie en particulier celle développée au XVIIIe siècle par Diderot et que l'on peut qualifier de matérialiste.

My Interest: From my backgrounds of interest in the theory of knowledge and methodology of science, I have been studying philosophy of Leibniz. Currently, my issue about this is focused on his remarkable texts concerning the problems of causality.

My current interests: I have studied Leibniz’s philosophy with the constant interest in a notion ‘vinculum substantiale’(substantial bond), which he showed a certain jesuit in his later years. Quite a few interpreters have thought this notion has connections with the theories of body, organism and relation between mind and body. While I have certainly agreed with this interpretation, I have thought ‘vinculum substantiale’ could be closely connected with these notions; ‘identity’, ‘individual’, ‘person’, ‘self’. At the same time, currently, I am not a little interested in two topics; 1. Individualistic ideas and the theories of logic and language in the Middle Ages, 2. The problems in contemporary analytical metaphysics, particularly self, identity, modality and ontology.
