Other philosophical connections.

Many authors have discussed similarities between Spinoza's philosophy and Eastern philosophical traditions. A few decades after the philosopher's death, Pierre Bayle, in his famous Historical and Critical Dictionary (1697) pointed out a link between Spinoza's alleged atheism with "the theology of a Chinese sect", supposedly called "Foe Kiao", of which he had learned thanks to the testimonies of the Jesuit missions in Eastern Asia. A century later, Kant also established a parallel between the philosophy of Spinoza and the thinking of Laozi (a "monstrous system" in his words), grouping both under the name of pantheists, criticizing what he described as mystical tendencies in them.
In 1863, Elijah Benamozegh purported to establish that the main source of Spinoza's ontology is Kabbalah. The most recent research in the field seems to vindicate that claim.
