Quine's essay, “Ontological Relativity”  has brought about not a little confusion and disagreement. What is Quine's doctrine, and what are his arguments for it? The following paragraphs search for an answer. First a word about my aims. I will avoid adding to the already extensive discussion of Quine's older thesis of the indeterminacy of translation. Instead, where connections between the old and new doctrines become apparent, I will focus on the connections themselves and their repercussions for ontological relativity.
