I am reading a novel "pride and prejudice" by Jane Austen. I am struggling with these lines in capter 8.?

When Darcy replied to Miss Bingley at the end of chapter "to whom this remark was chiefly addressed, 'there is meanness in all the arts which ladies sometimes condescend to employ for captivation. Whatever bears affinity to cunning is despicable.' Could anyone please help me to explain the meaning?
