One of the things left behind by the historians of science who undertook the Great Escape from the philosophy of science was a claim to normative judgment. The philosophy of science could look at scientific arguments and, using the epistemological tools at its disposal, come to a judgment concerning whether or not current or historical claims were worthy of the name “science”. Through epistemology, science could consolidate and build upon its gains, which was not the case with something more subjective, like art, or (possibly) politics.
If we may say that science is, therefore, progressive, it stands to reason that, with the benefit of philosophy, we can look back on history and identify scientific works that were either progressive or regressive. This is why Herbert Butterfield (1900-1979) did not feel it was appropriate to apply his notion of “whig history” to science. The notion is also central to the thought of Karl Popper (1902-1994), who thought that it was possible for epistemology to legitimize the assertion of those claims that stood because they had not been falsified, while delegitimizing those claims that were held as certainly true on account of illegitimate (i.e., social or political) prejudice, an action that necessarily falsified other claims prematurely. The Church’s suppression of Galileo, the suppression of relativity and quantum mechanics to the benefit of deutsche Physik, or the enshrinement of Lysenko’s genetics as the official state policy of the Soviet Union all constituted sure signs of the illegitimacy of the socio-political system that made these events possible in the face of an epistemologically overwhelming challenge.
Setting Popper aside, in this general philosophical point of view, scientific progress is made possible only through proper epistemology. The interference of society or politics represents an illegitimate interference with proper epistemology. The philosopher of science therefore is in a position to make normative judgments of current science and upon science’s historical development, as well as upon the political systems that either allowed science its autonomy or that interfered with its freedom.
For much of the 20th century, this point of view was opposed mainly by a Marxist philosophy of science, which held
