In the first place, you shouldn't believe in promises. The world is full of them: the promises of riches, of eternal salvation, of infinite love. Some people think they can promise anything, others accept whatever seems to guarantee better days ahead, as, I suspect is your case. Those who make promises they don't keep end up powerless and frustrated, and exactly the fate awaits those who believe promises.
When the time of danger comes, all Americans, whatever their social standing, whatever their creed, whatever the training they have received, no matter from what section of the country they have come, stand together as men, as Americans, and are content to face the same fate and do the same duties because fundamentally they all alike have the common purpose to serve the glorious flag of their common country.
I cherish the dreams of yesterday and dare not dwell on the err's of my past whose fate has been long decided, and effect I can not change. For the dreams of yesterday are the challenges of today, and the hope for tomorrow.
Concern for man himself and his fate must always form the chief interest of all technical endeavors, concern for the great unsolved problems of the organization of labor and the distribution of goods-in order that the creations of our mind shall be a blessing and not a curse to mankind. Never forget this in the midst of your diagrams and equations.
O friend, my bosom said,
Through thee alone the sky is arched.
Through thee the rose is red;
All things through thee take nobler form,
And look beyond the earth,
The mill-round of our fate appears
A sun-path in thy worth.
Me too thy nobleness has taught
To master my despair;
The fountains of my hidden life
Are through thy friendship fair.
