Only the most superficial mind would assert nowadays that man is a reasonable creature. Man is an unreasonable creature, and it was entirely unreasonable and human for Mr. Britling during his nocturnal self-reproaches to mix up his secret resentment at his infatuation for Mrs. Harrowdean with his ill-advised attack upon the wall of Brandismead Park. He ought never to have bought that car; he ought never to have been so ready to meet Mrs. Harrowdean more than halfway. What exacerbated his feeling about Mrs. Harrowdean was a new line she had recently taken with regard to Mrs. Britling. From her first rash assumption that Mr. Britling was indifferent to his wife, she had come to realise that on the contrary he was in some ways extremely tender about his wife. This struck her as an outrageous disloyalty. Instead of appreciating a paradox she resented an infidelity. She smouldered with perplexed resentment for some days, and then astonished her lover by a series of dissertations of a hostile and devastating nature upon the lady of the Dower House. He tried to imagine he hadn't heard all that he had heard, but Mrs. Harrowdean had a nimble pen and nimbler afterthoughts, and once her mind had got to work upon the topic she developed her offensive in half-a-dozen brilliant letters.... On the other hand she professed a steadily increasing passion for Mr. Britling. And to profess passion for Mr. Britling was to put him under a sense of profound obligation--because indeed he was a modest man. He found himself in an emotional quandary. You see, if Mrs. Harrowdean had left Mrs. Britling alone everything would have been quite tolerable. He considered Mrs. Harrowdean a charming human being, and altogether better than he deserved. Ever so much better. She was all initiative and response and that sort of thing. And she was so discreet. She had her own reputation to think about, and one or two of her predecessors--God rest the ashes of those fires!--had not been so discreet. Yet one could not have this sort of thing going on behind Edith's back. All sorts of things one might have going on behind Edith's back, but not this writing and saying of perfectly beastly things about Edith. Nothing could alter the fact that Edith was his honour.... Section 5 Throughout the week-end Mr. Britling had kept this trouble well battened down. He had written to Mrs. Harrowdean a brief ambiguous note saying, "I am thinking over all that you have said," and after that he had scarcely thought about her at all. Or at least he had always contrived to be much more vividly thinking about something else. But now in these night silences the suppressed trouble burst hatches and rose about him.
