I will mourn the loss of thousands of precious lives, but I will not rejoice in the death of one, not even an enemy. Returning hate for hate multiplies hate, adding deeper darkness to a night already devoid of stars. Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate, only love can do that.

Everything except the first sentence is found in King’s book, Strength to Love, and seems to have been said originally in a 1957 sermon he gave on loving your enemies.  Unlike the first quotation, it does sound like King, and it was easy to assume that the whole thing came from him.

So how did they get mixed together?

Thanks to Jessica Dovey, a Facebook user, that’s how.  And contrary to my initial assumption, it wasn’t malicious.  Ms. Dovey, a 24-year old Penn State graduate who now teaches English to middle schoolers in Kobe, Japan, posted a very timely and moving thought on her Facebook status, and then followed it up with the Martin Luther King Jr. quote. —Anatomy of a Fake Quotation – Megan McArdle – National – The Atlantic.
