How wise a man was David Hume?
Claimed "nothing for certain" can we know.
We can't know cause, it hides from view.
Our brain allows effect, the status quo.
Can we see an object outside our mind?
Not if an image comes through our eyes.
Our brain conjures up an image;
Then lets imagination revise.
Doubting Hume pursued an ordered life;
Causing many thinkers to doubt.
He coped and ate like a normal man.
Hunger needs food, he figured out.
