Themes in Harry Potter

The countdown continues...

I have enjoyed reading the HP books because JKR has woven so many themes into her books. This is unlikely to be a comprehensive list but I thought it might be amusing to note some.

Good vs Evil- Of course this has to be number one but I like also the idea (that JK hasn't had much opportunity to explore) that not all evil doers are from Slytherin house (or Durmstrang). That Harry himself could have easily been placed in Slytherin house. This leads on nicely to,

Working Together- it is only with the help of giants, elves, centaurs and other creatures is it possible to overcome the dark forces. I'm sure this will be further developed in the last book (hopefully with some co-operation between Slytherin and Gryffindor)

Sacrificial Love- Not only is Harry protected in his early years by the bond of love and sacrifice she made to keep him alive but the theme continues with Dumbledore and Harry himself putting others first. I'm wondering Dumbledore's death whether results in powerful magic that will finally conquer Voldy in book 7.

Redemption- Snape has turned from his Death Eater ways (or has he? The Snape Debate will be here tomorrow) and Malfoy was unable to kill Dumbledore. Also throughout the series, animals that are considered dangerous (Buckbeak, Thestrals) have their uses if you treat them with a little bit of care and respect.

Things Not As They Would First Appear-
Harry being safe with family who couldn't care less about him
Sirius Black
Tents at Quidditch World Cup
Triwizard Trophy
Hermione being muggle born but the best in her year at magic
House elves-slaves, but happy

Death Is Not A Bad Thing Really
Philosophers stone being destroyed and Flamell dying
Dumbledore's conversations with Voldemort
Dumbledore's death (and I'm sure conversations with his portrait in the new Headteachers office)

I'm sure you can think of a dozen more themes but I haven't time for any more so you can add them as a comment.
