Having a substructure analogous or identical to an overall structure. In mathematics, certain geometrical objects such as line segments and fractals are self-similar to an arbitrary level of magnification; many natural phenomena, such as clouds and plants, are self-similar to some degree.

As Garrett sums up, the Thanksgiving Ode volume aspires to a "'prospect-view' or grand imperial vision" of the nation as "an abstract unified whole, the self-contained and self-similar island nation united in purpose by the war with France" (10), but the poems in it are characterized by anxious self-consciousness and a nearly debilitating ambivalence; "when referred to at all, [they are] usually held up as the nadir of Wordsworth's career.
