 Spinoza later identifies this same geometrical relationship with the conceptual involvement relation (IIp49). What it is for things to follow from God necessarily is for those things to be (asymmetrically) conceived through God, whose concept involves (the concept of) existence. The necessity of God and the necessity of existing things are both explained by and grounded in conceptual relations. Spinoza makes this connection emphatic in Ip35, “Whatever we conceive to be in God’s power, necessarily exists.”
