He had walked up and down his study, his mind aflame; he had sat in his arm-chair, facing the moonlight, considering a question, to him so important, so far-reaching, that his mind at moments seemed as if like to snap, to break, but which was accepted by nine-tenths of humanity without a second thought, as lightly as the most superficial detail of daily life. But how others acted was not his concern; he must consider his own competence to bear the burden--the perilous burden he had asked, and which had been promised to him. He must not adventure into a life he was not fitted for; he must not wreck another's life; in considering himself he was considering her; their interests were mutual, they were identical; there was no question of egotism. But this marriage question had been debated a thousand times in the last six months; it had haunted his thought, it had become his daily companion, his familiar spirit. Under what new aspect could he consider this question? It faced him always with the same unmovable, mysterious eyes in which he read nothing, which told him nothing of what he longed to know. He only knew that he had desired this girl as a wife. A desire had come he knew not whence; and he asked himself if it were a passing weakness of the flesh, or if this passion abided in him, if it had come at last to claim satisfaction? On this point he was uncertain, this was nature's secret. In the midst of his stress of mind his eyes had wandered over his books; they had been caught by the colour of a small thin volume, and, obeying an instinct, he had taken the volume down. He knew it well; a few hundred small pages containing the wisdom of a great Greek philosopher, Epictetus, and John had often before turned to this sage discourse for relief in his mental depressions and despair of life. 'The subject for the good and wise man is his master faculty, as the body is for the physician and the trainer, and the soil is the subject for the husbandman. And the work of the good and wise man is to use appearances according to Nature. For it is the nature of every soul to consent to what is good and reject what is evil, and to hold back about what is uncertain; and thus to be moved to pursue the good and avoid the evil, and neither way for what is neither good nor evil.' In the light of these words John's mind grew serene as a landscape on which the moon is shining; and he asked himself why he had hesitated if marriage were the state which he was destined to fulfil? 'If a habit affects us, against that must we endeavour to find some remedy? And what remedy is to be found against a habit? The contrary habit.'
