Albus Dumbledore's letter to Lucius Malfoy

This letter was written by Albus Dumbledore to Lucius Malfoy in response to Lucius Malfoy's demand that Beedle the Bard's The Fountain of Fair Fortune be removed from the Hogwarts Library. The exact date of the letter's composition is unknown; however, based upon the fact that Lucius Malfoy mentions his son in his demand for a ban, it can be guessed that it was written after 5 June 1980.

Albus Dumbledore quoted this letter in his commentary on the story.[src]

The following is the portion of the letter Albus Dumbledore quoted in his commentary on The Fountain of Fair Fortune.

''So-called pure-blood families maintain their alleged purity by disowning, banishing or lying about Muggles or Muggleborns on their family trees. They then attempt to foist their hypocrisy upon the rest of us by asking us to ban works dealing with the truths they deny. There is not a witch or wizard in existence whose blood has not mingled with that of Muggles, and I should therefore consider it both illogical and immoral to remove works dealing with the subject from our students' store of knowledge.''[src]
