. . . Complete liberty to comment on the conduct of public men is a scalpel in the case of free speech. The sharp incision of its probe relieves the abscesses of officialdom. Men in public life may suffer under a hostile and an unjust accusation; the wound can be assuaged with the balm of a clear conscience. A public officer must not be too thin-skinned with reference to comment upon his official acts. Only thus can the intelligence and dignity of the individual be exalted. Of course, criticism does not authorize defamation. Nevertheless, as the individual is less than the State, so must expected criticism be born for the common good. Rising superior to any official or set of officials, to the Chief Executive, to the Legislature, to the Judiciary – to any or all the agencies of Government â€“ public opinion should be the constant source of liberty and democracy.”
