The past did not behold to-day; the future shall not. We must use it now if it is to be of any benefit to mankind.

So here hath been dawning
Another blue day;
Think, wilt thou let it
Slip useless away?

Out of Eternity
This new day is born;
Into Eternity,
At night will return.

Behold it aforetime
No eye ever did;
So soon it for ever
From all eyes is hid.

Here hath been dawning
Another blue day;
Think, wilt thou let it
Slip useless away?

Thomas Carlyle.
