Life is something we need to stop correcting

Gustav Klimt. Buchenhain, 1902

 Just began Bewilderment by Richard Powers.  This early section caught my eye.

I never believed the diagnoses the doctors settled on my son.  When a condition gets three different names over as many decades, when it requires two subcategories to account for completely contradictory symptoms, when it goes from nonexistent to the country's most diagnosed childhood disorder in the course of one generation, when two different physicians want to prescribe three different medications, there's something wrong.....

Watching medicine fail my child, I developed a crackpot theory: Life is something we need to stop correcting. My boy was a pocket universe I could never hope to fathom.  Every one of us is an experiment, and we don't even know what the experiment is testing.

The second paragraph has three tee-shirt-worthy epigrams:

Life is something we need to stop correcting.

My boy was a pocket universe I could never hope to fathom.

Every one of us is an experiment, and we don't even know what the experiment is testing. 

All of these things are about his son in the book, but I imagine that they'll be about the earth in general.  There's a metaphor (I'm assuming) between over-diagnosis of ADHD and humans' sense of "correcting" nature.  Why?  Because we can hope to fathom the complexity and specificity of the world and we don't know what the earth is designed for.
