Pride
Throughout the novel, pride prevents the characters from seeing the truth of a situation. Most notably, it is the primary barrier between Elizabeth and Darcy. Darcy's pride in his social position leads him to hate Elizabeth, because she is out of his social circle. Meanwhile, Elizabeth's pride in independence clouds her judgment. These two find happiness by helping each other overcome their pride. Although a few characters, like Mrs.Bennet and Miss Bingley, remain corrupted by personal pride.
Family
Mr. and Mrs.Bennet are examples of bad parenting. Lydia and Kitty's foolish behavior shows the suffering that came with the bad parenting. The Gardiner's are foil parents that have shown Jane and Elizabeth true advice and respect. Each daughter has traits of the parents or the role models.
Prejudice
Elizabeth has too much prejudice throughout the novel, because she quickly dislikes Darcy, who is a truthful gentlemen, but likes Mr.Collins, who is a lying jerk. Although Jane doesn't have any prejudice, and finds good in everyone. There is a clear difference in Elizabeth and Jane. The novel shows that prejudice can be both good and bad, and a certain amount is good and bad.
Love
Elizabeth and Jane marry for love, while Lydia and Charlotte get stuck in a marriage made out of security and comfort. Austen shows that love is powerful, and that women are allowed to have a mind of their own as well.
Overall Meaning
The novel is empowering to women and independence, because Elizabeth is able to speak her mind and end up with a happy marriage. The novel satires the rules of the British high society, and ultimately comes to the conclusion that the rules are nonsense. The ones who follow the rules, like Mrs.Bennet and Mr.Collins, are made out to be foolish and silly people, when actually, they are doing everything by the book. The audience takes the side of the independence of Elizabeth and roots for her happiness. The overall meaning is truth in oneself and complete satisfaction in independence.
