"In this life-long fight, to be waged by every one of us singlehanded against a host of foes, the last requisite for a good fight, the last proof and test of our courage and manfulness, must be loyalty to truth — the most rare and difficult of all human qualities. For such loyalty, as it grows in perfection, asks ever more and more of us, and sets before us a standard of manliness always rising higher and higher."
