This chapter develops a version of ontological pluralism that appeals to semantically primitive restricted quantification and naturalness. It also articulate different ways of formulating versions of ontological pluralism. Although the author defends ontological pluralism from some objections, the main goals of this chapter are to get some versions of ontological pluralism on the table, show that they are intelligible and worthy of consideration, and show how concerns about ontological pluralism connect up with historical and contemporary meta-metaphysical issues. The chapter considers versions of ontological pluralism that say that substances have a different mode of being than attributes, that things in time have a different mode of being than atemporal objects, that stuff has a different mode of being than things, and many others.
