In the Garden of Certainty

In the Garden of Certainty, nothing grows
but familiar fruit in straight-and-narrow rows.
I’m-Sure-I’m-Rights in bunches grow
next to Pithy Slogans and I-know-i-know.
No vermin here to eat away
at unchallenged truths of day-to-day.
To glimpse what life is all about
you’ll need to plant some Seeds of Doubt.
