Authored by political scientist Miroslav Novák, recipient of the 2024 Czech Political Science Association Award for his contribution to the development of Czech political science, the book persuasively argues that contemporary scholarship has significantly misunderstood Duverger’s work. In doing so, it calls for a reassessment not only of Duverger’s theories but also of prevailing narratives about the evolution of political science in the second half of the twentieth century.
