The "Published as `A Beautiful Thought...'" explanation is very unclear. It implies that the quote is not by Horace Mann, and was misattributed to him by William Mathews in 1874. However, the phrasing "is often quoted as an advertisement originally written by Mann" seems to contradict this and imply that it is an advertisement originally written by Mann. This is supported by the fact that it is listed under Sourced, rather than Misattributed. As an aside, it also appears in "The True Briton," 1851, without attribution, as sent in by reader "R. B."
So what's the deal with this quote? Is it by Mann or not? Prignillius 20:30, 19 August 2011 (UTC)
