The Role of Existential Quantification in Scientific Realism

Published online by Cambridge University Press:  17 April 2017

Abstract

Scientific realism holds that the terms in our scientific theories refer and that we should believe in their existence. This presupposes a certain understanding of quantification, namely that it is ontologically committing, which I challenge in this paper. I argue that the ontological loading of the quantifiers is smuggled in through restricting the domains of quantification, without which it is clear to see that quantifiers are ontologically neutral. Once we remove domain restrictions, domains of quantification can include non-existent things, as they do in scientific theorizing. Scientific realism would therefore require redefining without presupposing a view of ontologically committing quantification.

5 I am not claiming that Quinean's do hold a biconditional reading of NE, but rather that they need to in order to motivate TB or else there is a lack of argument for why quantification is taken to be existentially committing. It does nevertheless seem that they may hold the biconditional reading given that they seem to hold that non-existents lack determinate identity conditions and things with determinate identity conditions are existent things. I discuss this further in section 2.3.
