Descartes

Descartes, seeking mercy for his doubt,
double parked his car,
and, motor running,
let his wild thoughts
leap frog where they would
to flicker in his self appointed darkness.

In the convenience store, he ordered
sweet onions and some snuff.

If he could only cry and wildly sneeze! Or sing!
(or get a ticket from that pretty meter maid he saw)
Then, he thought, he wouldn't need to search
for moonlight under his closed lids,
nor heaven's proof in latin muttering.
