"Science is a magnificent force, but it is not a teacher of morals. It can perfect machinery, but it adds no moral restraints to protect society from the misuse of the machine. It can also build gigantic intellectual ships, but it constructs no moral rudders for the control of storm tossed human vessel. It not only fails to supply the spiritual element needed but some of its unproven hypotheses rob the ship of its compass and thus endangers its cargo."

“A man who murders another shortens by a few brief years the life of a human being; but he who votes to increase the burden of debts upon the people of the United States assumes a graver responsibility.”

“I have been so satisfied with the Christian religion that I have spent no time trying to find arguments against it. … I am not afraid now that you will show me any. I feel that I have enough information to live and die by.”

“In war, science has proven itself an evil genius; it has made war more terrible than it ever was before. Man used to be content to slaughter his fellowmen on a single plane — the earth's surface. Science has taught him to go down into the water and shoot up from below and to go up into the clouds and shoot down from above, thus making the battlefield three times a bloody as it was before; but science does not teach brotherly love. Science has made war so hellish that civilization was about to commit suicide; and now we are told that newly discovered instruments of destruction will make the cruelties of the late war seem trivial in comparison with the cruelties of wars that may come in the future.”

“If they believe it, they go back to scoff at the religion of their parents.”

“You cannot judge a man's life by the success of a moment, by the victory of an hour, or even by the results of a year. You must view his life as a whole. You must stand where you can see the man as he treads the entire path that leads from the cradle to the grave — now crossing the plain, now climbing the steeps, now passing through pleasant fields, now wending his way with difficulty between rugged rocks — tempted, tried, tested, triumphant.”

“Success is brought by continued labor and continued watchfulness. We must struggle on, not for one moment hesitate, nor take one backward step.”
