“Freedom of the press is to the machinery of the state what the safety-valve is to the steam engine: every discontent is by means of it immediately relieved in words—indeed, unless this discontent is very considerable, it exhausts itself in this way.  If, however, it is very considerable, it is as well to know of it in time, so as to redress it.”– Arthur Schopenhauer, “On Law and Politics” (trans. Hollingdale)
