ABSTRACT
Spinoza developed Descartes’ mathematical science of nature to the ultimate degree, claiming that a completed natural science would reveal the single reality underlying all of existence, natural, human and divine. Leibniz accepts and reinforces the requirement for complete explicability, and is driven by that to suggest that the reality that lies behind all the appearances of the world is an infinite universe of self-sufficient reasons, unified in the infinite understanding of something much more like a traditional Christian God.
