A teacher who is attempting to teach without inspiring the pupil with a desire to learn, is hammering cold iron.

Horace Mann died in 1859. Earliest reference found is in Mary Mann, ed., Thoughts Selected from the Writings of Horace Mann (1867); Mary was his second wife. The "writing" referenced is not identified.
Other early references are in Eclectic Magazine, Vol. 7, #6 (1868-06), and in The Myrtle, Vol. 24, #40 (1875-01-30).


Could this be a misattribution? I found the identical passage in Henry Ward Beecher’s /Eyes and Ears/ (1862), a collection of his columns in the /New York Ledger/ called “Thoughts as they Occur, by one who keeps his Eyes and Ears open”. See pp. 155-156 here: http://bit.ly/2rFLDCJ.
Never mind. That was a different quote that I don’t think I got from you! (I wonder where I /did/ get it!)
