Abstract
Humanists hold that the state should be organized along secular lines, as should society's central institutions. The principle lies at the core of the humanist outlook, and not only that, it embodies a view which many readers, perhaps most, will think plain common sense, perfectly civilized, and absolutely uncontroversial. This chapter discusses humanism's implications for political thought and practice. It holds that polity is fully secular if, and only if, the following principle is treated as fundamental to: the design of legislation; the design of core social and political institutions; the day‐to‐day operation of those institutions. The chapter considers some of the arguments which are, at present, most commonly directed against secularism. It also concentrates upon alternatives to secularism whose flaws are, perhaps, less immediately evident, and upon two in particular, namely a certain form of conservatism and a certain form of communitarianism.
