"I think mental illnesses are poorly understood – not just by the public at large but even by the professionals"
About this Quote
The first half of the line, about "the public at large", is almost expected. Stigma, ignorance, lazy stereotypes - none of that is news. The sting is in the second half: "even by the professionals". That phrase shifts the ground. It suggests that the problem is not simply bad public education but the limits of the field itself. Diagnosis can be contested, symptoms overlap, treatment is often probabilistic rather than precise. Theroux is pointing to the uneasy gap between the medical language of certainty and the lived reality of confusion.
The quote also reflects his larger method. Theroux has always been interested in people whom society flattens into types: the addict, the offender, the extremist, the "mad". His reporting resists that flattening. Here, the subtext is ethical as much as intellectual. If experts do not fully understand mental illness, then certainty becomes dangerous. It can harden into overconfidence, mislabeling, or a false sense that complex suffering has been neatly solved.
What makes the line effective is its restraint. Theroux does not dramatize mystery; he leaves room for humility. In a culture hungry for clean explanations, that humility feels almost radical.
