Enlisting Popper in the Case for Scientific Realism

Karl Popper fut un réaliste scientifique malgré lui. Au mépris de ses propres restrictions concernant les formes de raisonnement scientifique acceptables et la portée de l’évidence empirique, il insista sur une conception fortement réaliste des buts et des accomplissements de la science. Dans cet article, je construis une défense générale du réalisme scientifique, m’appuyant, au il des développements, sur celles des positions popperiennes qui font progresser l’argument, et critiquant celles qui l’entravent. Bien que la ligne argumentative d’ensemble soit mienne, je montre, par des attributions directes, que Popper partage mes conclusions réalistes, et pourquoi il les partage.Karl Popper was a scientific realist in spite of himself. In defiance of his own restrictions on acceptable forms of scientific reasoning and the reach of empirical evidence, he insisted on a strongly realist conception of the goals and achievements of science. In this article I mount a general defense of scientific realism, taking advantage, as I proceed, of those Popperian positions that advance the argument, and criticizing those that impede it. While the overall line of argumentation is my own, I show, through direct attributions, that and why Popper shares my realist conclusions
