The only time you really live fully is from thirty to sixty. The young are slaves to dreams; the old servants of regrets. Only the middle-aged have all their five senses in the keeping of their wits.
This country has nothing to fear from the crooked man who fails. We put him in jail. It is the crooked man who succeeds who is a threat to this country.
The teachings of the Bible are so interwoven and entwined with our whole civic and social life that it would be literally impossible for us to figure to ourselves what that life would be if these teachings were removed.
Nowadays the field naturalist-who is usually at all points superior to the mere closet naturalist-follows a profession as full of hazard and interest as that of the explorer or of the big-game hunter in the remote wilderness.
If there ever was a pursuit which stultified itself by its very conditions, it is the pursuit of pleasure as the all-sufficing end of life. Happiness cannot come to any man capable of enjoying true happiness unless it comes as the sequel to duty well and honestly done. To do that duty you need to have more than one trait. From the greatest to the smallest, happiness and usefulness are largely found in the same soul, and the joy of life is won in its deepest and truest sense only by those who have not shirked life's burdens.

Progress has brought us both unbounded opportunities and unbridled difficulties. Thus, the measure of our civilization will not be that we have done much, but what we have done with that much. I believe that the next half century will determine if we will advance the cause of Christian civilization or revert to the horrors of brutal paganism. The thought of modern industry in the hands of Christian charity is a dream worth dreaming. The thought of industry in the hands of paganism is a nightmare beyond imagining. The choice between the two is upon us.

Apart from this, yet mingled with it, is the strong attraction of the silent places, of the large tropic moons, and the splendor of the new stars; where the wanderer sees the awful glory of sunrise and sunset in the wide waste spaces of the earth, unworn of man, and changed only by the slow change of the ages through time everlasting.
In the Western Hemisphere the adherence of the United States to the Monroe Doctrine may force the United States, however reluctantly, in flagrant cases of such wrong doing or impotence, to the exercise of an international police power.
