A boy, presuming on his intellect,
Once showed two little monkeys in a cage
A burning-glass they could not understand
And never could be made to understand.
Words are no good: to say it was a lens
For gathering solar rays would not have helped.
But let him show them how the weapon worked.
He made the sun a pinpoint on the nose
Of the first one, then the other, till it brought
A look of puzzled dimness to their eyes
That blinking could not seem to blink away.
They stood arms laced together at the bars,
And exchanged troubled glances over life.
One put a thoughtful hand up to his nose
As if reminded--or as if perhaps
Within a million years of an idea.
He got his purple little knuckles stung.
The already known had once more been confirmed
By psychological experiment,
And that were all the finding to announce
Had the boy not presumed too close and long.
There was a sudden flash of arm, a snatch,
And the glass was the monkey's, not the boy's.
Precipitately they retired back-cage
And instituted an investigation
On their part, though without the needed insight.
They bit the glass and listened for the flavor.
They broke the handle and the binding off it.
Then none the wiser, frankly gave it up,
And having hid it in their bedding straw
Against the day of prisoners' ennui,
Came dryly forward to the bars again
To answer for themselves:
Who said it mattered
What monkeys did or didn't understand?
They might not understand a burning-glass.
They might not understand the sun itself.
It's knowing what to do with things that counts.
