Anticipatory obedience is a political tragedy.
Authoritarians need obedient civil servant, and concetration camp directors seek businessmen interested in cheap labor.
Lawyers were vastly overrepresented among the commanders of the Einsatzgruppen, the special task forces who carried out the mass murder of Jews, Gypsies, Polish elites, communists, the handicapped, and others. German (and other) physicians took part in ghastly medical experiments in the concentration camps. Businessmen from I.G. Farben and other German firms exploited the labor of concentration camp inmates, Jews in ghettos, and prisoners of war. Civil servants, from ministers down to secretaries, oversaw and recorded it all.
If lawyers had followed the norm of no execution without trial, if doctors had accepted the rule of no surgery without consent, if businessmen had endorsed the prohibition of slavery, if bureaucrats had refused to handle paperwork involving murder, then the Nazi regime would have been much harder pressed to carry out the atrocities by which we remember it.
Most governments, most the of the time, seek to monopolize violence. People and parties who wish to undermine democracy and the rule of law create and und violent organizations that envolve themselves in politics. Such groups can take the form of a paramilitar wing of a political party, the personal body guard of a particular politician - or apparently spontaneous citizen initiatives, wich usually turn out to haven been organized by aparty or its leader.
Authoritarian regimes usually include a special riot police force whose task is to disperse citizens who seek to protest, and a secret state police force whose assignments include the murder of dissenters or others designated as enemies.
Fascists rejected reason in the name of will, denying objective truth in favor of a glorious myth articulated by leaders who claimed to give voice to the people.
Fascists despised the small truths of daily existence, loved slogans that resonated like a new religion, and preferred creative myths to history or journalism. They used new media, which at the time was radio, to create a drumbeat of propaganda that aroused feelings before people had time to ascertain facts. And now, as then, many people confused faith in a hugely flawed leader with the truth about the world we all share.
Post-truth is pre-fascism.
“What is truth?” Sometimes people ask this question because they wish to do nothing. Generic cynicism makes us feel hip and alternative even as we slip along with our fellow citizens into a morass of indifference. It is your ability to discern facts that makes you an individual, and our collective trust in common knowledge that makes us a society. The individual who investigates is also the citizen who builds. The leader who dislikes the investigators is a potential tyrant.
