Summary Dominique Pagani often returns to two lessons from Leibniz. The first: no two identical leaves can be found in a park, so equality is a construction of the mind and does not exist in nature1 . The second: "there is no concrete except through the abstract," meaning that one must go through mathematics to know the world2 . He presents him as a jurist, a linguist and co-inventor of the infinitesimal calculus with Newton, and he also mentions the universal characteristic, binary and the motto "Calculemus." He borrows from him the image of the magnetic needle which, if it were conscious, would believe it wanted to go north, an illusion of consciousness exposed before Marx and Freud3 . He also takes up the double meaning of Unruhe, restlessness and the balance wheel of a clock4 , the small perceptions, the term "conspire" for the parts of an organism, and the monad, in which each individual is an absolute. He places him among the classical metaphysicians who think within God, whose totality remains spatial, unlike Hegel's, and he refuses to set him against Spinoza.

Who is this? Gottfried Wilhelm Leibniz (or Leibnitz; 1 July 1646 [O.S. 21 June] – 14 November 1716) was a German polymath active as a mathematician, philosopher, scientist, and diplomat. Alongside Isaac Newton, he is widely credited with the invention of calculus. He is also credited with making foundational contributions to other areas of mathematics, such as binary arithmetic and statistics. […]
