St. Anselm's approach was to define God as, "that than which nothing greater can be conceived". Famed pantheist philosopher Baruch Spinoza would later carry this idea to its extreme: "By God I understand a being absolutely <answer>infinite</answer>, i.e., a substance consisting of <answer>infinite</answer> attributes, of which each one expresses an eternal and <answer>infinite</answer> essence." For Spinoza, the whole of the natural universe is made of one substance, God, or its equivalent, Nature. His proof for the existence of God was a variation of the Ontological argument.
