Quote by Baruch Spinoza: “God or Nature.”

This phrase captures Spinoza's core idea that God and Nature are one and the same. It means that the divine isn't separate from the world, but is found in the very fabric and laws of the universe itself.

This foundational phrase from Spinoza's *Ethics* defines his monistic philosophy. He identified God not as a transcendent creator, but as the immanent, infinite substance underlying all reality, inseparable from the natural world.

Dutch philosopher of Portuguese-Jewish origin whose rationalist philosophy challenged religious orthodoxy and laid foundations for the Enlightenment. His masterwork Ethics, published posthumously in 1677, argued that God and Nature were one and the same substance.
