“The delight we inspire in others has this enchanting peculiarity that, far from being diminished like every other reflection, it returns to us more radiant than ever.”

Orthodoxy (1884)
Context: This century will be called Darwin’s century. He was one of the greatest men who ever touched this globe. He has explained more of the phenomena of life than all of the religious teachers. Write the name of Charles Darwin on the one hand and the name of every theologian who ever lived on the other, and from that name has come more light to the world than from all of those.

1910s, Address to the Knights of Columbus (1915)
Context: Four centuries and a quarter have gone by since Columbus by discovering America opened the greatest era in world history. Four centuries have passed since the Spaniards began that colonization on the main land which has resulted in the growth of the nations of Latin-America. Three centuries have passed since, with the settlements on the coasts of Virginia and Massachusetts, the real history of what is now the United States began. All this we ultimately owe to the action of an Italian seaman in the service of a Spanish King and a Spanish Queen. It is eminently fitting that one of the largest and most influential social organizations of this great republic, a republic in which the tongue is English, and the blood derived from many sources, should, in its name, commemorate the great Italian. It is eminently fitting to make an address on Americanism before this society. We of the United States need above all things to remember that, while we are by blood and culture kin to each of the nations of Europe, we are also separate from each of them. We are a new and distinct nationality. We are developing our own distinctive culture and civilization, and the worth of this civilization will largely depend upon our determination to keep it distinctively our own. Our sons and daughters should be educated here and not abroad. We should freely take from every other nation whatever we can make of use, but we should adopt and develop to our own peculiar needs what we thus take, and never be content merely to copy.
