What is repugnant to every human being is to be reckoned always as a member of a class and not as an individual person

In checking a translation of Dorothy Sayer's, I came across a book of hers, Are Women Human? Clickbait long before the internet.

Looking at some quoted passages, it looks like I need to add it to my shopping list.

A man once asked me ... how I managed in my books to write such natural conversation between men when they were by themselves. Was I, by any chance, a member of a large, mixed family with a lot of male friends? I replied that, on the contrary, I was an only child and had practically never seen or spoken to any men of my own age till I was about twenty-five. "Well," said the man, "I shouldn't have expected a woman (meaning me) to have been able to make it so convincing." I replied that I had coped with this difficult problem by making my men talk, as far as possible, like ordinary human beings. This aspect of the matter seemed to surprise the other speaker; he said no more, but took it away to chew it over. One of these days it may quite likely occur to him that women, as well as men, when left to themselves, talk very much like human beings also.

Individuals

In reaction against the age-old slogan, "woman is the weaker vessel," or the still more offensive, "woman is a divine creature," we have, I think, allowed ourselves to drift into asserting that "a woman is as good as a man," without always pausing to think what exactly we mean by that. What, I feel, we ought to mean is something so obvious that it is apt to escape attention altogether, viz: (...) that a woman is just as much an ordinary human being as a man, with the same individual preferences, and with just as much right to the tastes and preferences of an individual. What is repugnant to every human being is to be reckoned always as a member of a class and not as an individual person.

On movements

But it is the mark of all movements, however well-intentioned, that their pioneers tend, by much lashing of themselves into excitement, to lose sight of the obvious.

Advocates

I always said the professional advocate was the most amoral person on the face of the earth. I'm certain of it now.
