We cannot set a limit to the knowledge and love of man, because they spring from God, and move forever toward him who is without limit. That we have been made capable of this ceaseless approach to an infinite ideal is the radical fact in our nature. Through this we are human; through this we are immortal; through this we are lifted above matter, look through the rippling stream of time on the calm ocean of eternity, and beyond the utmost bounds of space, see simple being,—life and thought and love, deathless, imageless, absolute. This ideal creates the law of duty, for it makes the distinction between right and wrong. Hence the first duty of man is to make himself like God, through knowledge ever-widening, through love ever-deepening, through life ever-growing.

So only can we serve God, so only can we love him. To be content with ignorance is infidelity to his infinite truth. To rest in a lesser love is to deny the boundless charity which holds the heavens together and makes them beautiful, which to every creature gives its fellow, which for the young bird makes the nest, for the child the mother's breast, and in the heart of man sows the seed of faith and hope and heavenly pity.

Ceaseless growth toward God,—this is the ideal, this is the law of human life, proposed and sanctioned alike by Religion, Philosophy, and Poetry. Dulcissima vita sentire in dies se fieri meliorem.

Upward to move along a Godward way,
Where love and knowledge still increase,
And clouds and darkness yield to growing day,
Is more than wealth or fame or peace.

No other blessing shall I ever ask.
This is the best that life can give;
This only is the soul's immortal task
For which 't is worth the pain to live.

It is man's chief blessedness that there lie in his nature infinite possibilities of growth. The growth of animals comes quickly to an end, and when they cease to grow they cease to be joyful; but man, whose bodily development even is slow, is capable of rising to wider knowledge and purer love through unending ages. Hence even when he is old,—if he has lived for what is great and exalted,—his mind is clear, his heart is tender, and his soul is glad. Only those races are noble, only those individuals are worthy, who yield without reserve to the power of this impulse to ceaseless progress. Behold how the race from which we have sprung—the Aryan—breaks forth into ever new developments of strength and beauty in Greece, in Italy, in France, in England, in Germany, in America; creating literature, philosophy, science, art; receiving Christian truth, and through its aid rising to diviner heights of wisdom, power, freedom, love, and knowledge.

And so there are individuals—and they are born to teach and to rule—for whom to live is to grow; who, forgetting what they have been, and what they are, think ever only of becoming more and more. Their education is never finished; their development is never complete; their work is never done. From victories won they look to other battlefields; from every height of knowledge they peer into the widening nescience; from all achievements and possessions they turn away toward the unapproachable Infinite, to whom they are drawn. Walking in the shadow of the too great light of God, they are illumined, and they are darkened. This makes Newton think his knowledge ignorance; this makes Saint Paul think his heroic virtue naught. Oh, blessed men, who make us feel that we are of the race of God; who measure and weigh the heavens; who love with boundless love; who toil and are patient; who teach us that workers can wait! They are in love with life; they yearn for fuller life. Life is good, and the highest life is God; and wherever man grows in knowledge, wisdom, and strength, in faith, hope, and love, he walks in the way of heaven.

To you, young gentlemen, who are about to quit these halls, to continue amid other surroundings the work of education which here has but begun, what words shall I more directly speak? If hitherto you have wrought to any purpose, you will go forth into the world filled with resolute will and noble enthusiasm to labor even unto the end in building up the being which is yourself, that you may unceasingly approach the type of perfect manhood. This deep-glowing fervor of enthusiasm for what is highest and best is worth more to you, and to any man, than all that may be learned in colleges. If ambition is akin to pride, and therefore to folly, it is none the less a mighty spur to noble action; and where it is not found in youth, budding and blossoming like the leaves and flowers in spring, what promise is there of the ripe fruit which nourishes life? The love of excellence bears us up on the swift wing and plumes of high desire,—

Without which whosoe'er consumes his days,
Leaveth such vestige of himself on earth
As smoke in air or foam upon the wave.

Do not place before your eyes the standard of vulgar success. Do not say, I will study, labor, exercise myself, that I may become able to get wealth or office, for to this kind of work the necessities of life and the tendency of the age will drive you; whereas, if you hope to be true and high, it is your business to hold yourselves above the spirit of the age. It is our worst misfortune that we have no ideals. Our very religion, it would seem, is not able to give us a living faith in the reality of ideals; for we are no longer wholly convinced that souls live in the atmosphere of God as truly as lungs breathe the air of earth. We find it difficult even to think of striving for what is eternal, all-holy, and perfect, so unreal, so delusive do such thoughts seem.
