Our reading
An editorial interpretation.
A sharp observation that plain ignorance is far less harmful than the failure to recognize one's own ignorance in the first place. It highlights how overconfidence in flawed understanding causes more damage than simply not knowing, since awareness of gaps at least invites the chance to learn.
