I was going to post this yesterday, in honor of the observance of Dr. King's birthday, but I didn't get around to it.
I got the phrase "the joy of discovery" from my high school chemistry teacher, and I certainly felt it nearly 10 years ago, when my UU magazine published a never-before-transcribed MLK speech. Specifically it was a eulogy that Dr. King gave for James Reeb, a UU minister beaten to death while doing civil rights work in the Deep South.
How could a speech by this world-famous guy go unheralded for so many years? Well, Dr. King was a busy guy, so perhaps it's not surprising that a few of his papers got lost in the shuffle of life. Fortunately for all of us, someone unearthed a cassette tape of his eulogy, and it got transcribed at last.
Follow this link to an eyewitness account of the memorial service for Rev. Reeb, with links in the sidebar to a PDF of the text and an MP3 file of the sermon.
For me, it was just such a gift to find these new words so long after the speaker had been so wrongly silenced.

E.J. Dionne's short piece giving thanks that MLK did not die when he was stabbed in the chest back in 1958. (Please ignore the mostly dumb-ass comments, though.)
