While Ambrose praises Rachel’s intelligence, he also adds that she is different than other women. This shows that Ambrose is still a misogynist, despite his high regard for Rachel; he admires her
even though she is female. Furthermore, Ambrose claims to appreciate Rachel’s intelligence, but he seems more enthusiastic about the fact that she keeps her mouth shut, which suggests that he doesn’t genuinely respect Rachel or value her as an equal. Louise’s description of Rachel as probably “very charming” sheds further light on this, because it implies that Ambrose might be assigning “intelligence” to Rachel as a kind of euphemism for sex appeal. As the reader will come to see, Rachel is intelligent, charming,
and sexy, which makes her a formidable character indeed.
