The first known use of the term "pantheism" was in Latin ("pantheismus" ) by the English mathematician Joseph Raphson in his work "De Spatio Reali seu Ente Infinito", published in 1697. Raphson begins with a distinction between atheistic "panhylists" (from the Greek roots ', "all", and ', "matter"), who believe everything is matter, and Spinozan "pantheists" who believe in "a certain universal substance, material as well as intelligence, that fashions all things that exist out of its own essence." Raphson thought that the universe was immeasurable in respect to a human's capacity of understanding, and believed that humans would never be able to comprehend it. He referred to the pantheism of the Ancient Egyptians, Persians, Syrians, Assyrians, Greek, Indians, and Jewish Kabbalists, specifically referring to Spinoza.
