In mysticism that love of truth which we saw as the beginning of all philosophy leaves the merely intellectual sphere, and takes on the assured aspect of a personal passion. Where the philosopher guesses and argues, the mystic lives and looks; and speaks, consequently, the disconcerting language of first-hand experience, not the neat dialectic of the schools. Hence whilst the Absolute of the metaphysicians remains a diagram impersonal and unattainable the Absolute of the mystics is lovable, attainable, alive.
Idealism, though just in its premises, and often daring and honest in their application, is stultified by the exclusive intellectualism of its own methods: by its fatal trust in the squirrel-work of the industrious brain instead of the piercing vision of the desirous heart. It interests man, but does not involve him in its processes: does not catch him up to the new and more real life which it describes. Hence the thing that matters, the living thing, has somehow escaped it; and its observations bear the same relation to reality as the art of the anatomist does to the mystery of birth.
Therefore it is to a practical mysticism that the practical man is here invited: to a training of his latent faculties, a bracing and brightening of his languid consciousness, an emancipation from the fetters of appearance, a turning of his attention to new levels of the world. Thus he may become aware of the universe which the spiritual artist is always trying to disclose to the race. This amount of mystical perception this ordinary contemplation, as the specialists call it is possible to all men: without it, they are not wholly conscious, nor wholly alive. It is a natural human activity, no more involving the great powers and sublime experiences of the mystical saints and philosophers than the ordinary enjoyment of music involves the special creative powers of the great musician.
