A unidirectional view of causality is present in some monotheistic views of the world with a beginning and an end and a single great force with a single end (e.g., Christianity and Islam), while a cyclic worldview of causality is present in religious traditions which are cyclic and seasonal and wherein events and experiences recur in systematic patterns (e.g., Zoroastrianism, Mithraism and Hinduism). These worldviews of causality not only underlie religious traditions but also other aspects of thought like the purpose of history, political and economic theories, and systems like democracy, authoritarianism, anarchism, capitalism, socialism and communism.
