" Men – witness all the histories! – were subject to sudden lusts and violences, affairs that seemed strangely divorced from heart or head, and often more strangely still from what were surely their true characters. For them chastity was not a prime virtue: she remembered her amazement when she had discovered that so correct a gentleman and kind a husband as Sir John Denny had not always been faithful to his lady. Had Lady Denny cared? A little, perhaps, but she had not allowed it to blight her marriage. ‘Men, my love, are different from us,’ she had said once, ‘even the best of them! I tell you this because I hold it to be very wrong to rear girls in the belief that the face men show to the females they respect is their only one. I daresay, if we were to see them watching some horrid, vulgar prize-fight, or in company with women of a certain class, we shouldn’t recognise our own husbands and brothers. I am very sure we should think them disgusting! "
