The European Society for the History of Science expresses its grave alarm over the ongoing assaults on the academic freedoms of our colleagues in the United States and beyond. The Society’s core objectives include fostering cooperation and intellectual exchange between scholars in history of science, and the advancement of public education in the historical, cultural, and social aspects of science. While our geographic remit is European, assaults on the fundamental academic freedoms of our colleagues outside Europe are inescapably our concern also. We are troubled by the situation in many countries, including the United States. We stand in solidarity with our colleagues on the Association of University Presses, the American Council of Learned Societies, the National Humanities Alliance, and others in their criticism of attempts by government to punish universities for failure to bend to their ideological priorities. Such measures include, but are not restricted to, funding cuts and grant freezes. As historians of science and technology, we know all too well how such measures have been used in the past to control, marginalize, or silence unwelcome academic voices. We believe that such measures should have no place in twenty-first-century academic life, and that the health of democratic societies can only be harmed by attempts to restrict the freedom of speech and thought within universities.
