This mystery, which no philosopher had ever explained, seemed to him to run equally through the whole of nature. He asked himself whether he was in the presence of two warring forces. Would the Will, whatever it was, which produced happiness, have made that happiness permanent, if it could? was it thwarted by some other power, perhaps equally strong--though it seemed to Hugh that the happiness of most sentient beings decidedly and largely predominated over their unhappiness--a power which was deliberately inimical to joy and peace, health and well-being? It seemed to him, however, that the two were so inextricably intermingled, and so closely ministered, the one to the other, that there was an essential unity of Will at work; and that both joyful and painful experiences were the work of the same mind. He therefore rejected at the outset the belief that what was commonly called evil could be a principle foreign to the nature of the Will of God; and he put aside as childish the belief that evil is created by the faculty of human choice, setting itself against the benevolent Will of God; for benevolence thus hampered would at once become a mere tame and ineffective desire for the welfare of sentient things, and be wholly deprived of all the attributes of omnipotence. Besides, he saw the same qualities that produced suffering in humanity, such as the instincts of cruelty, lust, self-preservation, manifesting themselves with equal force among those sentient creatures which did not seem to be capable of exercising any moral choice. But in regarding nature, as revealed by the researches of scientists, he saw that there was a slow development taking place, a development of infinite patience and almost insupportable delay. Finer and finer became the organisation of animal life; and in the development of human life, too, he saw a slow progress, a daily deepening power of organising natural resources to gratify increasingly complicated needs. Not only was an energy at work, but a progressive energy, bringing into existence things that were not, and revealing secrets unknown before. He next attempted to define his moral belief; and here, too, he saw in the world a progressive force at work. He saw society becoming more and more refined, more desirous to amend faulty conditions, more anxious to alleviate pain; and this not only with self-regarding motives, but with a vital sympathy, which reached its height in the deliberate purpose of many individuals that, even if condemned to suffer themselves, they would yet spend thought and energy in relieving, if possible, the ills of others.
