. But other worlds he knew nothing of lay all about him. The
secrets of the rocks he had never suspected. Steam, electricity, the
growth of trees, the fall of snow,--all these were mysteries to him.
The only conquest he knew, the subjection of men's bodies, went but a
little way. All the men who in his lifetime knew the name of Alexander
the Great could find encampment on the Palo Alto farm. The great world
of men in his day was beyond his knowledge. His world was a very small
one, and of this he had seen but a little corner.

For the need of more worlds to conquer is no badge of strength. It is
the stamp of ignorance. It is the cry only of him who knows that the
great earth about him still stands unconquered. No Lincoln ever sighed
for more nations to save; no Luther for more churches to purify; no
Darwin that nature had not more hidden secrets which he might follow to
their depths; no Agassiz that the thoughts of God were all exhausted
before he was born.

And now, a final word to you as scholars: Higher education means the
higher sacrifice. That you are taught to know is simply that you may
do. Knowing the truth signifies that you should do right. Knowing and
doing have value only as translated into justice and love. There is no
man so strong as not to need your help. There is no man so weak that
you cannot make him stronger. There is none so sick that you cannot
bring him to the "gate called Beautiful." There is no evil in the
world that you cannot help turn to goodness. "We could lift up this
land," said Bjoernson of Norway, "we could lift up this land, if we
lifted as one."

Therefore lift, and lift as one. You are strong enough and wise
enough. You shall seek strength and wisdom, that others through you
may be wiser and stronger. You shall seek your place to work as your
basis for helpfulness. Others will make the place as good as you
deserve. If your lives are sacrificed in helping men, it is to the
market of the ages you carry your blood, not to the milk-market of
Concord town. The honest man will not "pledge himself in Germany to
teach nothing which is not true." Being true himself, he can teach
nothing false. The more men of the true order there are in the world,
the greater is the world's need of men.

As you are men, so will your places in life be secure. Every
profession is calling you. Every walk of life is waiting for your
effort. There will always be room for you, and e
