"The ultimate reason of things must lie in a necessary substance, in which the differentiation of the changes only exists eminently as in their source; and this is what we call God"
About this Quote
The key rhetorical move is “eminently.” Leibniz isn’t saying God contains every change the way a storage unit contains boxes. He’s saying the variety we see in the world exists in God as a higher, unified source: complexity without mess, multiplicity without fragmentation. It’s a philosopher’s version of compression, taking the world’s noisy data and positing a single, sufficient encoding.
The subtext is a defense of intelligibility. Leibniz is writing in a Europe where the new sciences are explaining more and more without invoking miracles, and where religious conflict has made “God” politically combustible. His gambit is to relocate divinity from the arena of competing churches to the architecture of explanation itself. God is not primarily the thunderbolt-thrower but the guarantor that the universe is, at bottom, rationally accountable.
It also telegraphs his wider project: the Principle of Sufficient Reason and the hope that reality is optimized, not arbitrary. If you buy the premise that everything must have a reason, this conclusion isn’t pious ornamentation; it’s the system’s keystone.
