Ismaili philosophy fundamentally bridges western and eastern thought. The focus of practice and thought in Ismailism is always on the esoteric, or internal. It’s essential in Ismaili thought that every action and word has a deeper internal meaning. Just as the Quran affirms the pursuit of Abrahamic Monotheism before Islam, Ismaili philosophy affirms the search for Ultimate Truth outside of its own religion. In Ismailism, a scientific pursuit is a form of spiritual pursuit. Therefore, schools of thought from other religions (or even secular schools) are accepted into Nizari philosophy. Works from authors such as Confucius, Plato, Aristotle, Isaac Newton, and even Charles Darwin are in Nizari thought.
