The belief that a society or a nation can be unified - its barriers of religion, class, and race broken down - by bringing its children together in common schools that express a lowest-common-denominator vision of national life is a persistent theme throughout the 19th and 20th centuries, and has especially been evoked against schools created by immigrant groups to teach their children within their own religious tradition.

Critics like Jeff Spinner-Halev counter that pluralism is a positive social good, and allows individuals freedom to shape their own lives in terms of real choices:

A relentless diversity flattens the pluralism of society. … A pluralistic society is not a place where every institution mirrors the ethnic, racial, and gender composition of society.  A pluralistic society has different kinds of groups with different kinds of memberships. …  This kind of society will offer its members more choices than one that is diverse “all the way down.” … the irony of a diversity that is taken too far: eventually it makes society more homogeneous rather than heterogeneous. ... A society that has different institutions with different audiences, customers, clienteles, or students will be more pluralistic than a society where all the institutions are composed of the same people.

Advocates for an educational system that encourages non-government schooling argue that freedom in educational provision and the pluralism of the education provided requires the flourishing of alternatives to the schools operated by government, but only if these alternative schools are not compelled – or seduced – into adopting a pédagogie d’état which makes them essentially similar to government schools.

For the sake of freedom of conscience and of expression – itself founded on the principle of tolerance as well as ideological and philosophical principles of non-discrimination – no educational monopoly by the state can be justified within the democratic order. Freedom of conscience and expression are meaningless if children are subjected to mandatory indoctrination in a particular viewpoint selected by the state. (more…)
