The Pessimist

Here is a tale for uncles and old aunties:
There was a man once who denied the Devil,
Yet in the world saw nothing else but evil;
A pessimist, with face as sour as Dante's.
Still people praised him; men he loathed and hated,
And cursed beneath his breath for wretched sinners,
While still he drank with them and ate their dinners,
And listened to their talk and tolerated.
At last he wrote a book, full of invective
And vile abuse of earth and all its nations,
Denying God and Devil, Heaven and Hades.
Fame followed this. "His was the right perspective!"
"A great philosopher!" He lost all patience.
But still went out to dine with Lords and Ladies.
