Stray birds of summer come to my window to sing and fly away. And yellow leaves of autumn, which have no songs,flutter and fall there with a sigh.

"The past is a country we can never return to, but whose borders we are always crossing."

It is only through enforced standardization of methods, enforced adoption of the best implements and working conditions, and enforced cooperation that this faster work can be assured.

We live in a world of shadows, and we ourselves are shadows.
