(uncountable, usually) Synonym of ecumenism.
- He [Gottfried Wilhelm Leibniz] corresponded so heavily that scholars are still sorting through his unpublished papers. In his philosophy he practised an ecumenicism that in a lesser mind would strike us as suspicious or even craven. Leibniz seems never to have met a philosopher or a theologian he didn’t like, and his metaphysics developed out of an effort to harmonise the ancient thinking of (both) Plato and Aristotle with tenets of Christian and Jewish theology and with the ‘mechanical philosophy’ the Royal Society had been created to champion. It is impossible to know precisely what he was thinking without perusing his vast legacy of papers. In effect, Leibniz’s philosophy ceased to exist at the moment he died. Since then, anyone who has wanted to know it has first had to reconstruct it, which is only possible for forensically inclined scholars, fluent in Latin, French and German, and well versed in the history of Western philosophy, Christian theology and Enlightenment science. 2010, Neal Stephenson, “Atoms of cognition: metaphysics in the Royal Society, 1715–2010”, in Bill Bryson, editor, Seeing Further: The Story of Science and the Royal Society, Mariner Books, →ISBN, page 62:
