23.
But this is clear, what is forever was,
So far as actual substance is concerned;
We need not look for any primal cause
Of Being, nor of any of its laws;
They were, and are, and will be, when is burned
The last of all we now behold below—
Will be when countless cycles have returned,
And countless others shall return and go;
All was, and is, and will be—more we cannot know.
