The Harry Potter series introduced fans to a magical world full of wit and wisdom. The series featured several older wizards guiding Harry and his friends on a journey to defeat the evil Lord Voldemort. One of the greatest of these wizards that provided Harry, specifically, with advice was Professor Albus Percival Wulfric Brian Dumbledore.

The Headmaster of Hogwarts School of Witchcraft and Wizardry played a more behind-the-scenes role in the earlier Harry Potter books, but would still drop some pearls of wisdom for Harry. Some of them were funny, while others were inspiring, but he delivered some all-time great quotes.

10 After Harry's Battle With Quirrell

Professor Dumbledore delivers a clever line when Harry Potter wakes up after defeating Quirrell and Voldemort in Harry Potter and the Sorcerer's Stone. It plays on how much school administrators actually know what's going on despite how often the students think they are pulling the wool over someone's eyes:

"What happened down in the dungeons between you and Professor Quirrell is a complete secret...so, naturally, the whole school knows."

Harry went into the dungeon to prevent Snape from stealing the Sorcerer's Stone only to find out that Quirrell was the one stealing it, not Snape. Dumbledore lets him know that their battle has been kept a secret, but secrets aren't kept very well.

9 On Choice Versus Ability

Another pearl of wisdom Dumbledore delivers to Harry Potter comes after defeating Tom Riddle and the basilisk in Harry Potter and the Chamber of Secrets. Harry has felt disconnected from his fellow students, due to many believing him to be the Heir of Slytherin. Concerned that he should be in Slytherin instead of Gryffindor, Harry tells Dumbledore the only reason he is in Gryffindor is that he didn't want to be in Slytherin, to which Dumbledore responds:

“It is our choices, Harry, that show what we truly are, far more than our abilities.”

Dumbledore teaches Harry why his choice is important, and why it makes him just as true a Gryffindor as any other. Both houses can foster his abilities, but only one of the two houses could properly represent his choices.

8 On Trelawney's Psychic Powers

Dumbledore's wit shines through with this quote from Harry Potter and the Prisoner of Azkaban. Professor Trelawney made a prediction about the future, and Harry described it as different from her usual predictions. Dumbledore addresses the prediction and believes she may have made a real one, saying:

"That brings her total of real predictions up to two. I should offer her a pay raise."

He uses a joke to acknowledge that this has happened before, and that he should increase her pay. This references the prophecy fans learn about later in the series. It provides a lighthearted moment that foreshadows the darker path that the later books take.

7 What Is Right, And What Is Easy

This quote from Harry Potter and the Goblet of Fire demonstrates the tough times the Wizarding world is about to experience and how it will affect everyone, whether they are wizard or muggle. Everyone will come to a fork in the road, and must decide which path they will walk. The decision will test every one of them:

“Dark and difficult times lie ahead. Soon we must all face the choice between what is right, and what is easy.”

This is a part of life that is true for everyone. While most of us won't be fighting a wizard hell-bent on controlling the world, we still must make choices. It's sage advice for everyone, but especially for Harry and his friends in the context of the series.

6 On Fear And Oppression

This quote from Harry Potter and the Half-Blood Prince perfectly sums up the greatest villains in history. People who fear something try to stop it from happening. Tyrants have oppressed people throughout history. They were afraid someone could lead the people to revolt. This is what Dumbledore tries to help Harry understand:

"Have you any idea how much tyrants fear the people they oppress?"

In the Harry Potter series, this is an accurate depiction of Voldemort and the Death Eaters. They are attacking those without magic, those with magic who come from families without magic, and anyone who stands with the others who are oppressed. While it's been known for six books that Voldemort is the villain, this quote describes everything about his evil nature.

5 On The Foolishness Of Fighting Him

While Dumbledore can be sage, insightful or funny, this quote from Harry Potter and the Order of the Phoenix is a little bit of all three, as well as threatening. The Minister of Magic is determined to silence Dumbledore, who has been warning people about Voldemort's return.

When the Minister learns of what is basically a planned insurrection, he plans to pin it on Dumbledore. The Hogwarts Headmaster admits to it, but refuses to surrender. Cornelius Fudge asks Dumbledore if he is willing to fight the Minister, his Under Secretary at the school, and two aurors (wizard police). The headmaster of Hogwarts responds:

"Not unless you are foolish enough to force me to."

Dumbledore didn't really want to fight them, but he was willing if the others forced his hand. And he did everything he said he would, proving he was as adept with his wand as he was with his words.

4 On Harry's Strong Language

Sometimes kids, while venting frustration, say things in front of adults they shouldn't. While many times that will lead to punishment, Dumbledore chooses to ignore the issue with this quote from Harry Potter and the Goblet of Fire. Harry has just called Rita Skeeter a "cow" for what she wrote about Hagrid. He apologizes for using strong words, to which Dumbledore replies:

"I have gone temporarily deaf and haven’t any idea what you said, Harry."

Dumbledore was trying to cheer up Hagrid, and understood that punishing Harry for using an insulting phrase wouldn't help the situation. Hagrid was upset that details about his life were released in the press, and Dumbledore understood that Harry's outrage on his behalf would probably help Hagrid at the moment. Still, it was a sign that Harry shouldn't use the phrase again.

3 On Bertie Botts' Beans

This funny quote from Harry Potter and the Sorcerer's Stone helps bring some levity following the battle in the dungeon. Since everyone knows about Harry's secret adventures, they have sent him gifts in the hospital wing. One of those gifts is Bertie Botts Every Flavor Beans, which can be delicious or dreadful. After telling Harry that he didn't like them because he once ate a vomit flavored bean, Dumbledore tries to show solidarity by eating what he thinks is a toffee flavored bean, but:

"Alas! Earwax."

Dumbledore's pick turns out to be a bit less pleasant than he had hoped. It's a funny moment at a time when the first book needed to regain the kid's book feel it had before the dungeon adventure.

2 A Few Words

This is easily the most unusual way a character has ever been introduced into a popular book series. In Harry Potter and the Sorcerer's Stone, Dumbledore wants to say a few words before the Welcoming Feast begins. That's when he delivers these lines.

"Nitwit! Blubber! Oddment! Tweak!"

Dumbledore is the wisest character in the books and is identified as the greatest wizard ever. It seems odd to introduce him in such away, but it helped make him seem more human than if he just walked in making bold proclamations and giving sage advice right away. It also highlights his somewhat eccentric, whimsical nature.

1 On The Nature Of Adventure

Daniel Radcliffe as Harry Potter. Michael Gambon as Albus Dumbledore.

This Dumbledore quote from Harry Potter and the Half-Blood Prince sums up the entire series. As Dumbledore takes Harry away from the Dursleys to go meet Horace Slughorn, he says:

“And now, Harry, let us step out into the night and pursue that flighty temptress, Adventure.”

This particular jaunt is a fun adventure that leads to the introduction of an important character. But many adventures throughout the series, have turned negative for Harry and his friends. It demonstrates how adventure can be wonderful but also dreadful. That's why Dumbledore describes it as a "flighty temptress."
