 What it takes to be ultimate is to be the most fundamentally real, valuable or fulfilling among all that there is or could be. Historically, philosophy of religion in the West has taken God to be ultimate. Over the past century, the field has become increasingly aware that ultimacy is grasped under different concepts in the world’s religions, philosophies and quasi-religious philosophies—so not only as “God” but also as, e.g., “Brahman”, “the Dao”, and more. Moreover, people have thought to conceptualize each of these ultimates in numerous ways across cultures and times, so there are many models of Brahman, many models of God, many models of the Dao, and more; perhaps there is even a model of what is ultimate for each person who has thought hard about it. This entry presents a framework for understanding this vast landscape of models of God and other ultimates and then surveys some of its major sights. Familiarity with this landscape can clarify the long journey to deciding whether there is anything ultimate, among other benefits.
