Each of us comes for a short visit,
Not knowing why, yet sometimes
Seeming to divine a purpose.
From the standpoint of daily life, however,
There is one thing we do know:
That man is here for the sake of other men,
Above all for those whose smile and
Well-being our own happiness depends,
And also for the countless unknown souls
With whose fate we are connected
By a bond of sympathy,
Many times a day I realize how much
My own outer and inner life is built upon
By the labors of my fellow man,
Both living and dead, and how earnestly
I must exert myself in order to give in return
As much as I have received.
The World as I see It, Albert Einstein
