Wilde isn't simply telling us to question authority—he's suggesting that borrowed thoughts aren't thoughts at all, they're mere echoes, and there's a real moral difference between the two. A person parroting conventional wisdom, however respectfully, has abdicated the fundamental work of consciousness itself. Consider someone nodding along with their profession's standard practices for decades without once asking *why*: they may be competent, even successful, but Wilde would argue they've missed being a thinking being. The sting of his observation lies in its implied question—are you thinking, or merely remembering what you've been told to believe?
