If the reasoning by which her friends justified her course was somewhat cruder and less complex than her own elucidation of the matter, both explanations led to the same conclusion: John Arment was impossible. The only difference was that, to his wife, his impossibility was something deeper than a social disqualification. She had once said, in ironical defence of her marriage, that it had at least preserved her from the necessity of sitting next to him at dinner; but she had not then realized at what cost the immunity was purchased. John Arment was impossible; but the sting of his impossibility lay in the fact that he made it impossible for those about him to be other than himself. By an unconscious process of elimination he had excluded from the world everything of which he did not feel a personal need: had become, as it were, a climate in which only his own requirements survived. This might seem to imply a deliberate selfishness; but there was nothing deliberate about Arment. He was as instinctive as an animal or a child. It was this childish element in his nature which sometimes for a moment unsettled his wife’s estimate of him. Was it possible that he was simply undeveloped, that he had delayed, somewhat longer than is usual, the laborious process of growing up? He had the kind of sporadic shrewdness which causes it to be said of a dull man that he is “no fool”; and it was this quality that his wife found most trying. Even to the naturalist it is annoying to have his deductions disturbed by some unforeseen aberrancy of form or function; and how much more so to the wife whose estimate of herself is inevitably bound up with her judgment of her husband! Arment’s shrewdness did not, indeed, imply any latent intellectual power; it suggested, rather, potentialities of feeling, of suffering, perhaps, in a blind rudimentary way, on which Julia’s sensibilities naturally declined to linger. She so fully understood her own reasons for leaving him that she disliked to think they were not as comprehensible to her husband. She was haunted, in her analytic moments, by the look of perplexity, too inarticulate for words, with which he had acquiesced to her explanations.
