 Leibniz advocated the geometrical model of demonstration as the ideal form for metaphysics throughout his career. He claimed later in his career that he had all the materials at hand to compose a work that was a close approximation of the ideal. Yet such a work he did not compose. Why did Leibniz not make more progress on this task, which would seem to be of such great importance? Leibniz often mentioned his lack of free time as the reason for not completing an esoteric treatise. But this seems to provide an incomplete explanation of the situation. Though his extra-philosophical duties were numerous and burdensome, he made the time to write quite a lot on metaphysical subjects. If he thought that the geometrical model of demonstration was indeed the ideal form for metaphysics, one cannot help but wonder why he did not find the time to begin composing such a work.
