European politicians in Germany and France are increasingly denouncing free speech, particularly the libertarian concept of natural rights associated with it. French President Macron and German Chancellor Merz have criticized the notion of unrestricted online speech, viewing it as a danger to established order. These statements coincide with ongoing European efforts to regulate social media platforms and limit online expression. Instances of individuals facing arrest in Germany and Britain for online posts highlight the suppressive environment. European regimes often euphemistically frame censorship as necessary to combat "hate speech" or "disinformation." However, critics argue this allows ruling elites to arbitrarily define acceptable discourse. The author contends that such restrictions undermine truth-seeking and critical thinking. Historical figures like Vilfredo Pareto emphasized the absolute necessity of free speech for discovering objective truth. Pareto argued that all theories, even fundamental ones, must be open to challenge. He rejected any exceptions, even for humanitarian dogmas, believing only rigorous debate leads to truth. The author sees the current European assault on free speech as a symptom of declining historical liberalism. While the US has not reached this extreme, foundations for similar restrictions are being laid through political rhetoric and proposed legislation. The erosion of free speech, the author warns, poses a threat to fundamental liberties.
