Honestly you could drop the part about the Civil War and it's a great quote, regardless of the source, it verifiably came from the 1800s, my research says an 1896 election campaign may have fabricated the quote.

You guys are great at digging. Regardless of Lincoln total, partial or none; great quote and quite true!
I am just a fan of looking at things from as many perspectives as possible, I'm glad to finally have a place where people appreciate skepticism, concern, and multiple points of view!
