We need the iron qualities that go with true manhood. We need the positive virtues of resolution, of courage, of indomitable will, of power to do without shrinking the rough work that must always be done.
We must become bigger than we have been: more courageous, greater in spirit, larger in outlook. We must become members of a new race, overcoming petty prejudice, owing our ultimate allegiance not to nations but to our fellow men within the human community.
Enlightenment is man's emergence from his self-imposed nonage. Nonage is the inability to use one's own understanding without another's guidance. This nonage is self-imposed if its cause lies not in lack of understanding but in indecision and lack of courage to use one's own mind without another's guidance. Dare to know!
