In the idealistic movement of the late nineteenth and early twentieth centuries, British philosophy under Hegelian influence endeavoured to demonstrate the rationality of the universe as based on logical construction. The keynote of the Hegelian dialectic, as interpreted by both F. H. Bradley and J. E. McTaggart is that the mind is there from the first. In the advance from the bare abstraction of Being to the fully concrete whole—“Before the mind there is a single conception, but the whole mind itself which does not appear, engages in the process, operates on the datum, and produces the result.” The idea expressed by poetry in Tennyson's “Flower in the crannied wall,” which as the mind is fixed upon it reveals in an expansion to the universe the nature of God and Man, illustrates in a simple way the central philosophic conception of the British metaphysical idealists. Poetry could overlook the hard struggle of the little plant to keep its foothold against crowding competitors. Philosophy was perhaps too oblivious of this in its compelling postulate of the all pervading unity in which every difference and seeming contradiction would be reconciled.
