“Each people can do justice to itself only if it does justice to others”
Theodore Roosevelt (1858–1919) American politician, 26th president of the United States
1910s, The World Movement (1910)
Context: Each people can do justice to itself only if it does justice to others; but each people can do its part in the world movement for all only if it first does its duty within its own household. The good citizen must be a good citizen of his own country first before he can with advantage be a citizen of the world at large.
