(_β_) When, however--this is a _further_ point--the circle of ideas enlarges with the appearance of methodical modes of thought the ways in which idea is associated with idea increase, and in this very process the ability to use it increases also, and the expression of speech is elaborated in all the fluency of which it is capable. When this is so the position of poetry on the side of verbal expression is wholly changed. In other words, we have now a nation possessing the fully developed prose speech of everyday life, and poetic expression must now, in order to retain its interest, swerve aside from ordinary parlance, and receive a resurrection under the re-moulding energy of genius.[9] In our daily life the contingency of the moment is the motive of speech. In the creation of a work of art, however, we must have deliberate circumspection[10] in the place of instantaneous feeling; even the spirit of enthusiasm must be judiciously restrained. The creation of genius should be permitted to unfold itself from the artistic repose,[11] and become informed under the prevailing temper of an intelligence[12] that surveys the whole with clarity. In former times this spirit of concentration and tranquillity is to be inferred from the fact and utterance of poetry itself. In a more recent age, on the contrary, the nature of the composition and execution has itself to enforce the distinction which obtains between the expression of poetry and prose. In this respect poems which belong to epochs in which we find already an elaborated prose diction differ essentially from those of times and peoples in which the art originates.
