The human mind has adequate knowledge of God's essence
Formal Statement
The human mind has an adequate knowledge of the eternal and infinite essence of God.
In Plain Language
This is one of Spinoza's most audacious claims. Every idea of a body involves God's eternal essence (II.P45-46), and these ideas are adequate (II.P46). So the knowledge of God is not locked away behind faith or revelation — it is built into the very structure of any adequate idea you form. Whenever you truly understand something, you are, whether you know it or not, grasping a facet of God's nature. Necessity is not an abstract postulate; it is something you can concretely know.
Why This Follows
Step 7 (df-07) showed that reason perceives things under a form of eternity — the eternity of God's nature. This step makes it explicit: the human mind can and does have adequate knowledge of that eternal nature. This grounds the whole project: if we could not know necessity, understanding it could not liberate us.
Knowledge of God/Nature is not esoteric — it is the content of every adequate idea.

Does this claim feel too strong? What would it take for "adequate knowledge of God's essence" to be something ordinary, not something reserved for saints or geniuses?
