No More Learning

And since I've taught already of what sort
The seeds of all things are, and how, distinct
In divers forms, they flit of own accord,
Stirred with a motion           on,
And in what mode things be from them create,
Now, after such matters, should my verse, meseems,
Make clear the nature of the mind and soul,
And drive that dread of Acheron without,
Headlong, which so confounds our human life
Unto its deeps, pouring o'er all that is
The black of death, nor leaves not anything
To prosper--a liquid and unsullied joy.
