Sometimes our scientific advances demonstrate that our ordinary way of speaking about the world is wrong. Sometimes, however, they show exactly how our ordinary descriptions get things right.
In this paper, I give a framework for working out which of the two cases we are in. I suggest we think about how science can reveal indeterminacy in our ordinary language. When this occurs, we should respond by thinking about what we want our ordinary talk to do for us. As a case study, I’ll examine the exchange between Arthur Eddington and Susan Stebbing regarding the significance of the Rutherford-Bohr model of the atom for our ordinary solidity judgements.
The major consequence of this proposal is that it requires us to reflect on ourselves and our lives as well as the world. To determine whether our ordinary talk is proven wrong by science we must think about what we want to do with our everyday speech. This requires taking a leaf out of Bernard Williams’ book. Namely, it requires doing philosophy as a humanistic discipline.
