The essay “On Generosity” holds a special place among Leibniz’s ethical writings. In no other text does Leibniz give such prominence to the concept of generosity, or relate it to his central doctrine of justice as the charity of the wise. The circumstances of the piece’s composition are uncertain. Watermark dating of the paper places it in the period 1686-1687. The Academy editors suggest a connection between it and a text by an unknown author, “Discours sur la generosité,” a transcription of which is found among Leibniz’s manuscripts. The paper on which this latter text is written is dated by watermark to the same period as “On Generosity,” and the editors plausibly speculate that Leibniz’s reading of it may have spurred the composition of his own essay on the topic.

Leibniz raises three main objections to the doctrine of occasionalism: (1) it is inconsistent with the supposition of finite substances; (2) it presupposes the occurrence of "perpetual miracles"; (3) it requires that God "disturb" the ordinary laws of nature. At issue in objection (1) is the proper understanding of divine omnipotence, and of the relationship between the power of God and that of created things. I argue that objections (2) and (3), on the other hand, derive from a particular conception of the intelligibility of nature, a conception to which Leibniz is firmly committed and that occasionalists like Malebranche no less firmly reject

This is the most up-to-date and comprehensive interpretation of the philosophy of Gottfried Wilhelm Leibniz. Amongst its other virtues, it makes considerable use of unpublished manuscript sources. The book seeks to demonstrate the systematic unity of Leibniz's thought, in which theodicy, ethics, metaphysics and natural philosophy cohere. The key, underlying idea of the system is the conception of nature as an order designed by God to maximise the opportunities for the exercise of reason. From this idea emerges the view that this world is the best of all possible worlds, and an ethical ideal in which the well-being of human beings is promoted through the gradual extension of intellectual enlightenment.
