Nothing Real Outside God
If God knows everything about a thing perfectly, in what sense does the thing exist apart from him? Lessing's private notes press the question to the edge of Spinoza.
Writing to Mendelssohn, Lessing agrees that Spinoza put Leibniz on the track of pre-established harmony, being the first whose system showed that every change in a body could follow from its own mechanical forces, but only on the track: the working out was Leibniz's. A short argument of 1763 goes further. If God's idea of a thing contains every determination it has, nothing remains to make the thing real outside him, and God's ideas of real things might as well be the things themselves.

- Spinoza, you write, only put Leibniz on the track of his idea that body and soul keep time without acting on each other. What did Leibniz add?
- Anyone who believes in a creator wants the world to be something other than God. Does your short argument on things outside God leave room for that difference?
- God's ideas of real things, you suggest, might as well be the things themselves. Are we then living inside a thought of God?
- You agree that Leibniz owes Spinoza a hint but not his system. Why does it matter so much where a philosopher's idea first came from?
