Princeton, with its Old School Presbyterian heritage, had stronger sectarian theological ties than other leading schools. President James McCosh, an accomplished Scottish philosopher, helped modernize the college while still keeping a strong religious presence. In famous debates with Charles Eliot in the 1880s, he argued that freedom always works within limits. His successor, Francis Patton, was rigorously conservative in his Presbyterian orthodoxy but ran Princeton very much as a gentlemen’s club. Woodrow Wilson as president helped professionalize the university but remained loyal to broad Christian ideals. As at other schools of the era, the most vigorous religious expressions were in student voluntary associations.
