“It is a mere truism to say that every nation, whether in America or anywhere else, which desires to maintain its freedom, its independence, must ultimately realize that the right of such independence cannot be separated from the responsibility of making good use of it.”

“Each one must do his part if we wish to show that the nation is worthy of its good fortune.”

“The nation behaves well if it treats its natural resources as assets which it must turn over to the next generation increased, and not impaired, in value.”

“More and more it is evident that the State, and if necessary the nation, has got to possess the right of supervision and control as regards the great corporations which are its creatures.”

“And it is through strife and the readiness for strife that a man or a nation must win greatness. So, let the world know that we are here and willing to pour out our blood, our treasure, our tears. And that America is ready and if need be desirous of battle”

“I wish to preach, not the doctrine of ignoble ease, but the doctrine of the strenuous life, the life of effort, labor and strife; to preach that highest form of success which comes, not the the man who desires mere easy peace, but to the man who does not shrink from danger, from hardship, or from bitter toil, and who out of these wins the splendid ultimate triumph.”

“There is a delight in the hardy life of the open.There are no words that can tell the hidden spirit of the wilderness, that can reveal its mystery, its melancholy and its charm.The nation behaves well if it treats the natural resources as assets which it must turn over to the next generation increased; and not impaired in value.Conservation means development as much as it does protection.”
