Of this changed outlook the growth of Symbolism is the most significant literary expression.  It was not confined to France, or to poetry.  We know how the drama of Ibsen became charged with ulterior meanings as the fiery iconoclast passed into the poet of insoluble and ineluctable doubt.  But by the French symbolists it was pursued as a creed, as a religion.  If the dominant poetry of the third quarter of the century reflected the prestige of science, the dominant poetry of the fourth reflected the idealistic reactions against it, and Villiers de l’Ile Adam, its founder, came forward proclaiming that ‘Science was bankrupt’.  And so it might well seem to him, the visionary mystic inhabiting, as he did, a world of strange beauty and invisible mystery which science could not unlock.  The symbolists had not all an explicit philosophy; but they were all aware of potencies in the world or in themselves which language cannot articulately express, and which are yet more vitally real than the ‘facts’ which we can grasp and handle, and the ‘respectable’ people whom we can measure and reckon with.  Sometimes these potencies are vaguely mysterious, an impalpable spirit speaking only by hints and tokens; sometimes they are felt as the pulsations of an intoxicating beauty, breaking forth in every flower, but which can only be possessed, not described; sometimes they are moods of the soul, beyond analysis, and yet full of wonder and beauty, visions half created, half perceived.  Experiences like these might have been described, as far as description would go, by brilliant artificers like the Parnassians.  Verlaine and Mallarme did not discover, but they applied with new daring, the fact that an experience may be communicated by words which, instead of representing it, suggest it by their colour, their cadences, their rhythm, their verbal echoes and inchoate phrases.  All the traditional artistry of French poetic speech was condemned as both inadequate and insincere.  ’Take eloquence and wring her neck!  Nothing but music and the nuance—­all the rest is “Literature”, mere writing—­futile verbosity!’ that was the famous watchword of Verlaine’s creed.[12]

The strength of symbolism lay in this demand for a complete sincerity of utterance.  Its revolt against science was at the same time a vindication of truth, an effort to get nearer to reality both by shedding off the incrustations of habitual phrase and by calling into play the obscure affinities by which it can be magically evoked.  In the subtleties of suggestion latent in sensations the symbolists were real discoverers.  But the way had already been pointed in famous verses by Baudelaire: 

    ’Earth is a Temple, from whose pillared mazes
    Murmurs confused of living utterance rise;
    Therein Man thro’ a forest of symbols paces,
    That contemplate him with familiar eyes.

    As prolonged echoes, wandering on and on,
    At last in one far tenebrous depth unite,
    Impalpable as darkness, and as light,
    Scents, sounds, and colours meet in unison.’
