“His air of failure had nothing desperate about it; rather, it seemed to stem from an unresented realisation that he was not cut out for success, and his duty was therefore to ensure only that he failed in the correct and acceptable fashion.”

“After a long analysis of Robson’s suicide, we concluded that it could only be considered philosophical in an arithmetical sense of the term: he, being about to cause an increase of one in the human population, had decided it was his ethical duty to keep the planet’s numbers constant.”

“Back then, things were plainer: less money, no electronic devices, little fashion tyranny, no girlfriends. There was nothing to distract us from our human and filial duty which was to study, pass exams, use those qualifications to find a job, and then put together a way of life unthreateningly fuller than that of our parents, who would approve, while privately comparing it to their own earlier lives, which had been simpler, and therefore superior.”

“In the letter he left for the coroner he had explained his reasoning (for suicide): that life is a gift bestowed without anyone asking for it; that the thinking person has a philosophical duty to examine both the nature of life and the conditions it comes with; and that if this person decides to renounce the gift no one asks for, it is the moral and human duty to act on the consequences of that decision. ... Alex showed me a clipping from the Cambridge Evening News. 'Tragic Death of "Promising" Young Man.' ... The verdict of the coroner's inquest had been that Adrian Flinn (22) had killed himself 'while the balance of his mind was disturbed.' ... The law, and society, and religion all said it was impossible to be sane, healthy, and kill yourself.

“He loved his mother: doesn't that warm your silly, sentimental, twentieth-century heart? He loved his father. He loved his sister. He loved his niece. He loved his friends. He admired certain individuals. But his affections were always specific; they were not given away to all comers. This seems enough to me. You want him to do more? You want him to 'love humanity', to goose the human race? But that means nothing. Loving humanity means as much and as little as loving raindrops, or loving the Milky Way. You say that you love humanity? Are you sure you aren't treating yourself to easy self-congratulation, seeking approval, making certain you're on the right side?”

“The heap of dirty dishes was normal for Arthur, who had applied for a reduction in his water rate on the grounds that he washed up only every fortnight, and then used the leftover liquid for watering his roses.”

“If a man cannot tell what he wants to do, then he must find out what he ought to do. If desire has become complicated, then hold fast to duty.”
