No country can develop its full strength so long as the parts which make up the whole each put a feeling of loyalty to the part above the feeling of loyalty to the whole.

Context

“the effect upon a nation's growth to greatness of what may be called organized patriotism, which necessarily includes the substitution of a national feeling for mere local pride; with as a resultant a high ambition for the whole country. No country can develop its full strength so long as the parts which make up the whole each put a feeling of loyalty to the part above the feeling of loyalty to the whole. This is true of sections and it is just as true of classes. The industrial and agricultural classes must work together, capitalists and wageworkers must work together, if the best work of which the country is capable is to be done.” source
