In a letter to Henry Oldenburg he states that: "as to the view of certain people that I identify god with nature (taken as a kind of mass or corporeal matter), they are quite mistaken".[1] For Spinoza, our universe (cosmos) is a mode under two attributes of Thought and Extension. God has infinitely many other attributes which are not present in our world. According to German philosopher Karl Jaspers, when Spinoza wrote "Deus sive Natura" (God or Nature) Spinoza meant God was Natura naturans not Natura naturata, and Jaspers believed that Spinoza, in his philosophical system, did not mean to say that God and Nature are interchangeable terms, but rather that God's transcendence was attested by his infinitely many attributes, and that two attributes known by humans, namely Thought and Extension, signified God's immanence.[2]
