The two forms of nationalism that Tamir sees as resurgent today fit
Berlin’s classification, more or less. On the one hand, there are the
territorial, secessionist claims for national self-determination made
by, for example, Catalan or Kurdish nationalist movements. Liberals tend
to think of these as healthy, since the principle of self-determination
itself is an artefact of the enlightenment, which transfers the idea of
individual liberty from the person to the nation."
