4. Cum Prodiisset


 

4.3 Souverain Principe



Brief Summary:

Another of Leibniz’s formulations of his law of continuity is: “the rules of the finite succeed in the infinite, and conversely.”



Summary

 

As a basic principle, all things are governed by reason [[the world is not irrational but operates in accordance with rational law-like regularities]]. For this reason, the “the rules of the finite succeed in the infinite, and conversely.” (KS 579). This is another formulation of the law of continuity.
[[Perhaps Leibniz is noting that both the infinitely small and the finite coincide in the world, but it cannot be that the some parts of the world are governed by some laws, and other parts by other laws, especially when considering that the infinitely small parts reside compositionally within finite bodies.]]
