substances share the same attributes (Identity of Indiscernibles)

- God, or Nature, IS everything and everything is in it

“naturated nature”

Soazig Le Bihan - University of Montana

God did not “create the world by an act of free will”Necessary unfolding of its nature: how is this free?

Spinoza on Freedom - Freedom does not require contingency- Freedom = absence of external constraints and autonomy:

One does what one does for no other cause than oneself

Against traditional religion: “Superstition”Finalist, Anthropomorphic, Human-centered morality, Worship Why do we reason this way? Analogy with ourselvesXenophanes: if cows had Gods, these Gods would have horns

Why is it damageable? Ignorance, Superstition and Unhappiness

Why is it false? Necessary unfolding, God does not lack anything
