There are many perspectives for analysing and measuring the viability of a society: from GDP, competitiveness, individual freedoms, military strength to demographic stability, openness, social cohesion, eudaimonia. There is also a modern heuristic crystallised from centuries of observation: societies that turn against Jews are already turning against their own internal freedoms, institutions, and moral order. The argument that antisemitism reliably signals deeper political and moral breakdown appears in contexts from Enlightenment and 19th‑century debates on civic and religious equality to post‑WWII diagnostics of institutional collapse. What can we learn about the state of the UK’s System 4 and System 5 from examining the current antisemitism crisis through a cybernetic lens?
