“You'd think (losing his job and degree for having made false claims as a researcher) would be a lesson to him," said Miss Hillyard. "It didn't pay, did it? Say he sacrificed his professional honour for the women and children we hear so much about -- but in the end it left him worse of."But that," said Peter, "was only because he committed the extra sin of being found out.”

“...Perhaps you didn't say much about him, mother, but Gerald said lots - dreadful things!''Yes,' said the Duchess, 'he said what he thought. The present generation does, you know. To the uninitiated, I admit, dear, it does sound a little rude.”

“In fact, there is perhaps only one human being in a thousand who is passionately interested in his job for the job's sake. The difference is that if that one person in a thousand is a man, we say, simply, that he is passionately keen on his job; if she is a woman, we say she is a freak.”

“Now, it is frequently asserted that, with women, the job does not come first. What (people cry) are women doing with this liberty of theirs? What woman really prefers a job to a home and family? Very few, I admit. It is unfortunate that they should so often have to make the choice. A man does not, as a rule, have to choose. He gets both. Nevertheless, there have been women ... who had the choice, and chose the job and made a success of it. And there have been and are many men who have sacrificed their careers for women ... When it comes to a choice, then every man or woman has to choose as an individual human being, and, like a human being, take the consequences.”

“Philip wasn't the sort of man to make a friend of a woman. He wanted devotion. I gave him that. I did, you know. But I couldn't stand being made a fool of. I couldn;t stand being put on probation, like an office-boy, to see if I was good enough to be condescended to. I quite thought he was honest when he said he didn't believe in marriage -- and then it turned out that it was a test, to see whether my devotion was abject enough. Well, it wasn't. I didn't like having matrimony offered as a bad-conduct prize.”

“He remembered having said to his uncle (with a solemn dogmatism better befitting a much younger man): "Surely it is possible to love with the head as well as the heart." Mr. Delagardie had replied, somewhat drily: "No doubt; so long as you do not end by thinking with your entrails instead of your brain.”

“The only ethical principle which has made science possible is that the truth shall be told all the time. If we do not penalize false statements made in error, we open up the way for false statements by intention. And a false statement of fact, made deliberately, is the most serious crime a scientist can commit.”
