Summary |
When an ontologist asks "what exists?," a meta-question may soon follow: What is meant here by 'exists'? Quine's influential view is that 'exist' should be regimented as an existential quantifier, so that our ontological commitments are determined by the range of the quantifier, within our best scientific theory. In opposition, Carnap held that some existential statements are not ontologically committing. E.g., the statement 'There is an even prime' (if meaningful at all) is merely true by definition within the
"mathematics framework." That is so, even though the sentence may be
false in, say, the framework of evolutionary biology. Accordingly, for Carnap to "exist" is a pluralistic affair, relativized to a framework. Beyond the Quine-Carnap debate, other issues regarding existence include the classic question "Why is there anything at all?" as well as the riddle of non-being: "There exist things that do not exist" has the shape of a contradiction, but it also can seem true, thanks to Pegasus, unicorns, etc. Finally, and relatedly, some have suggested that there are different "ways of being," i.e., that there is more than one way to exist. Whether this is tenable is currently receiving much attention in the literature. |
