Yet the life had a danger which Hugh did not at first perceive. It tended to concentrate his thoughts too much upon himself. His writings took on a personal colour, a warm, self-regarding light, of which his candid friends did not hesitate to make him aware. The bitterness of the slow progress of a book, and of the long time that must elapse between its execution and its appearance, is that the readers of it tend to consider that it reflects the exact contemporary thought of its writer. Hugh's mind and personality grew fast in those days; and by the time that his friends were criticising a book as the outcome of his immediate thought, he was feeling himself that it was but a milestone on the road, marking a spot that he had left leagues behind him. But the creative instinct, which had struggled fitfully with the hard practical conditions of his professional life, now took a sudden bound forward. His writing became the one important thing in the world for Hugh. He had gained, he found, through constant practice, dry as the labour had been, a considerable fluency and firmness of touch: now sentences shaped themselves under his hand like living things; words flowed easily from their abundant reservoir. Yet the peril, which he soon grew to perceive, was that his outfit of emotional experience, his knowledge of human life in its breadth and complexity, was very narrow and limited. He had seen life only under a single aspect, and that an aspect which, poignant and intense as it was, did not easily lend itself to artistic treatment. The result was that his outlook was a narrow one, and his mind was driven back upon itself. The need to speak, to express, to shape thoughts in appropriate words, so long repressed, so instinctive to him, became almost fearfully imperative. He was haunted by a hundred ardent speculations in art, in literature, in religion, in metaphysics, all of a vague rather than a precise kind. His mind had been always of a loose, poetical type, turning to the quality of things rather than to outward facts or practical questions. Temperaments, individualities, appealed to him more than national movements or aspirations; and then the old love of nature came back like a solemn passion.
