In this passage from "Middlemarch," the characters are discussing Miss Brooke's potential marriage to a man viewed unfavorably by Sir James. He suggests that the man lacks vitality or passion, indicating that he is not suitable for Miss Brooke. This commentary reflects differing opinions about the nature of love and marriage, hinting at deeper societal values and expectations.
Mrs. Cadwallader adds a clever remark, implying that the man's qualities are not genuine or robust, likening his blood to a grammatical construct filled with semicolons and parentheses. This comparison suggests that he is overly complicated or lacking in true substance, emphasizing the idea that he may not be a suitable partner for someone like Miss Brooke, who deserves more than just intellectual complexity without emotional depth.
