“In the mid-nineteenth century it was said that the outstanding men of the Presbyterian world were Thomas Chalmers, Henry Cooke, and Charles Hodge....The earnest Christian spirit that breathed in the circle in which his early years were spent was not without its influence on Charles Hodge. When he was still but young, his godly widowed mother, for the education of her sons, took up house at Princeton. Here in his college days her husband had studied and graduated in the days of President Witherspoon, and with this home of American Presbyterianism her distinguished son was to be associated through his long life. In turn his sons and his grandson are also associated with it. And this long connection has given rise to the Princeton puzzle, ‘What is Princeton?’ with its answer, ‘An everlasting possession of the Hodges and the Alexanders.’” — John Macleod, Some Favourite Books, pp. 96-97
