Structural Realism, Then and Now
By Arthur Fine
Henri Poincaré worried that the ephemeral nature of scientific théories could be seen as amounting to the "bankruptcy of science". Recently his defense of scientific solvency has been understood as a kind of realism, structural realism. I begin by sorting realism from objectivity in the background of this conception, looking briefly at Russell and Weyl in addition to Poincaré. I then move to a critical examination of the current status of this form of realism.
