“When the Christian crusaders in the Orient came across that invincible order of Assassins – that order of free spirits par excellence whose lowest order received, through some channel or other, a hint about that symbol and spell reserved for the uppermost echelons alone, as their secret: “nothing is true, everything is permitted”. Now that was freedom of the spirit, with that, belief in truth itself was renounced.”
