In Assassin’s Creed lore, what phrase summarizes the Assassin Brotherhood’s core maxim?

“Nothing is true; everything is permitted” is the core maxim associated with the Assassin Brotherhood in Assassin’s Creed lore.

The phrase expresses the Brotherhood’s rejection of unquestioned authority and rigid certainty. It does not simply mean that reality is unreal or that every action is harmless; within the series, it is presented as a warning that institutions can shape what people accept as truth and that freedom requires responsibility.

The maxim is strongly associated with Altaïr Ibn-La'Ahad and the Assassin tradition. It appears in different forms across the games and is often discussed alongside the Brotherhood’s three central principles: stay your blade from the flesh of an innocent, hide in plain sight, and never compromise the Brotherhood.

“Requiescat in pace” is a phrase associated with Ezio, while the other alternatives are not established Brotherhood maxims.
