The conditions of consciousness, however, are far from being its only theme. As consciousness bears a transcendent relation to the dynamic world (for it is actual and spiritual, while the dynamic is potential and material) so it may be exuberant and irresponsibly rich. Although its elements, in point of distribution and derivation, are grounded in matter, as music is in vibrations, yet in point of character the result may be infinitely redundant. The complete musician would devote but a small part of his attention to the basis of music, its mechanism, psychology, or history. Long before he had represented to his mind the causes of his art, he would have proceeded to practise and enjoy it. So sense and imagination, passion and reason, may enrich the soil that breeds them and cover it with a maze of flowers.
The theme of consciousness is accordingly far more than the material world which constitutes its basis, though this also is one of its themes; thought is no less at home in various expressions and embroideries with which the material world can be overlaid in imagination. The material world is conceived by digging beneath experience to find its cause; it is the efficacious structure and skeleton of things. This is the subject of scientific retrospect and calculation. The forces disclosed by physical studies are of course not directed to producing a mind that might merely describe them. A force is expressed in many other
