Abstract

Popper and Agassi diverged on nationalism. Popper was a trenchant critic whereas Agassi formed a theory of liberal nationalism. At the root of their disagreement was Popper’s refusal of Jewish identity and rejection of Zionism, in contrast with Agassi’s affirmation of progressive Jewishness and liberal Zionism. Both Agassi and Popper, however, rejected ethnonationalism. To hedge against it, they ignored the claims of ethnocultural communities. This essay will highlight Agassi’s liberal theory of the nation state but urge that we overcome Critical Rationalists’ instinctive aversion to ethnicity, and accommodate ethnocultural communities. We should also explore again both Popper’s democratic imperialism and cosmopolitan diasporas, to think a future beyond nationalism.
