"While it may be fairly said that Mr. Lincoln entertained many Christian sentiments, it cannot be said that he was himself a Christian in faith or practice. He was no disciple of Jesus of Nazareth. He did not believe in his divinity and was not a member of his Church.
"He was at first a writing Infidel of the school of Paine and Volney, and afterwards a talking Infidel of the school of Parker and Channing....
"If the Churches had grown cold -- if the Christians had taken a stand aloof -- that instant the Union would have perished. Mr. Lincoln regulated his religious manifestations accordingly. He declared frequently that he would do anything to save the Union, and among the many things he did was the partial concealment of his individual religious opinions. Is this a blot upon his fame? Or shall we all agree that it was a conscientious and patriotic sacrifice?"
— -- The New York World (about 1875), quoted from Franklin Steiner, The Religious Beleifs of Our Presidents, pp. 138-39
here's another way to see it
How much to homecare workers get paid? What about baby sitters and nannies?
And here's the clincher ... how much do you think you have to pay to get a more than good but competent and trustworthy homecare worker, baby sitter or nanny?
THAT'S the difference in labor-value we are talking about here when we talk about women being paid less because blahdeeblah.
