The quarrel of the poet and the philosopher has at no time been more in evidence than at present. The unspeculativeness of contemporary poetry is almost a creed. Poets, if they are to be read, must take a solemn pledge to confine their range of subject-matter to fleeting impressions of the world of sense. The quarrel was only less in evidence in the period just before the present one, at the time when the cry, "art for art's sake," held the attention of the public. At that time philosophers could point out that Walter Pater, the molder of poet's opinions, had said, "It is possible that metaphysics may be one of the things which we must renounce, if we would mould our lives to artistic perfection." This narrowness of interest, this deliberate shutting of one's self up within the confines of the physically appealing, has been believed to be characteristic of all poets. The completeness of their satisfaction in what has been called "the aesthetic moment" is the death of their philosophical instincts. The immediate perception of flowers and birds and breezes is so all-sufficing to them that such phenomena do not send their minds racing back on a quest of first principles. Thus argue philosophers. Such a conclusion the poet denies. The philosopher, to whom a sense-impression is a mere needle-prick, useful only as it starts his thoughts off on a tangent from it to the separate world of ideas, is not unnaturally misled by the poet's total absorption in the world of sense. But the poet is thus absorbed, not, as the philosopher implies, because he denies, or ignores, the existence of ideas, but because he cannot conceive of disembodied ideas. Walter Pater's reason for rejecting philosophy as a handicap to the poet was that philosophy robs the world of its sensuousness, as he believed. He explained the conception of philosophy to which he objected, as follows: To that gaudy tangle of what gardens, after all, are meant to produce, in the decay of time, as we may think at first sight, the systematic, logical gardener put his meddlesome hand, and straightway all ran to seed; to _genus_ and _species_ and _differentia_, into formal classes, under general notions, and with--yes! with written labels fluttering on the stalks instead of blossoms--a botanic or physic garden, as they used to say, instead of our flower-garden and orchard.
