A timely diagnosis of the problem of rampant dishonesty
But as Cass Sunstein’s book shows, solving it is harder. "What is wrong with saying things that are not true? In some cases, nothing. Mr Sunstein does not share the Kantian view that lying is wrong on principle, instead taking J.S. Mill’s utilitarian stance that it is bad when it hurts people. This leaves room for white lies. One reason falsehoods should normally be considered protected speech is that officials are not sufficiently well-informed to second-guess citizens as to whether a given lie is beneficial. They also cannot reliably tell whether someone is lying or merely deluded. Most important, punishing falsehoods would deter others from voicing their opinions, or even their imprecise memories."
