When I read this quote, I think of Aphris. She was proud, even haughty, when it came to her own beauty; she was self-assured and confident; she was quick-tongued, quick-witted, and quick to anger. In my mind, spirit is about intelligence, not lack thereof. A Gorean man is interested in the whole woman, and that means she'd better have brains as well as beauty. He doesn't want some mousy wallflower who never has an opinion and who doubts her own worth. No, he wants a woman who knows who and what she is, both inside and out, and how glorious that is -- and who still submits to him at the end of the day.
A spirited woman is smart enough, passionate enough, and dedicated enough to keep her Master. She will invent new ways to please him and carry out those plans with a brazeness that makes his jaw drop, his eyes widen, his heart thunder. He will feel that he has an exquisite, priceless woman, a treasure to make other men envious.
