What constitutes a scientific discovery? What role do discoveries play in science, its dynamics and social practices? Must every discovery be attributed to an individual discoverer (or a small number of discoverers)? The paper explores these questions by first critically examining extant philosophical explications of scientific discovery—the models of scientific discovery, propounded by Kuhn, McArthur, Hudson, and Schindler. As a simple, natural and powerful alternative, we proffer the “change-driver model”: in a nutshell, it takes discoveries to be cognitive scientific results (...) that have epistemically advanced science. The model overcomes the shortcomings of its precursors, whilst preserving their insights. We demonstrate its intensional and extensional superiority, especially with respect to the link between scientific discoveries and the dynamics of science, as well as the award system of science. Both as an illustration, and as an application to a recent scientific and political controversy, we apply the considered models of discovery to one of the most momentous discoveries of science: the expansion of the universe. We oppose the 2018 proposal of the International Astronomers’ Union as too simplistic vis-`a-vis the historical complexity of the episode. The change- driver model yields a more nuanced and circumspect verdict: (i) The redshift-distance relation shouldn’t be named the “Hubble-Lemaître Law”, but “Slipher-Lundmark-Hubble-Humason Law”; (ii) Its interpretation in terms of an expanding universe, however, Lemaître ought to be given credit for; but (iii) The establishment of the expansion of the universe, as an evidentially sufficiently warranted result, is a communal achievement, emerging in the 1950s or 1960s.

I develop three arguments in support of my contention that we should favor achievements over agents as objects of fitting moral admiration. The first argument impugns the epistemic standing with which characterological admiration is standardly issued. The second argument alleges that there is likely to be a difference between widely held folk concepts of character and traits, on the one hand, and an empirically supported view of the reality of those things, on the other. The final argument concerns one way (...) in which characterological admiration renders some aspects of our practices of admiring subject to undesirable revision. In each case I use an analogy to athletic admiration to show how achievement admiration avoids the problems of characterological admiration. I then suggest an alternative role for characterological considerations in fitting admiration, as a loose constraint on what is appropriate to admire rather than as an object of admiration. The upshot of the article is theoretical, inasmuch as it develops a tension between the conditions governing fitting admiration and an empirically informed view of character. But there is also practical upshot, especially in the context of public practices of admiring, as when we build statues of heroes or name buildings after them. (shrink)
