Quine's ontological relativity

Quine's ontological relativity suggests that our understanding of what exists depends on the framework or language we use. Different perspectives or "worldviews" may interpret concepts differently, so there's no absolute, universal way to define what exists. Our beliefs about reality are influenced by our scientific theories, language, and culture, which shape how we categorize and interpret the world. Essentially, what we consider real is relative to the conceptual system we adopt, highlighting that existence isn't an objective fact independent of our intellectual constructs.
