On 28 January 1919, Max Weber gave his lecture Politik als Beruf, Politics as a Vocation, in Munich. In it he described the true civil servant. The official should not engage in politics. He should administer, and above all he should be impartial.
Sine ira et studio, „ohne Zorn und Eingenommenheit“ soll er seines Amtes walten. He should carry out his office without anger and without bias. The Latin phrase comes from the opening of the Annals of Tacitus. Weber then named what belongs to the politician instead: Parteinahme, Kampf, Leidenschaft. Taking sides, struggle, passion.
