This paper assesses two instruments of power: the miranda and credenda of power. These instruments can be found in different power systems and regimes: in ancient Greece, Islamic medieval states or even in Modern Middle Easter states. The first approach is historical, which helps to understand the origin of the miranda and credenda of power. The second approach is theoretical, which helps to show both the miranda and credenda of power that are used to assess the claims to the justification of power. As a critique, this paper shows that semi-democracies, fascist states, theocracies, and communist regimes use these instruments excessively to justify their power. Abuse of such instrument is only possible by generating “negative political consciousness” of which aim is to make folks to become rightless and powerless. Such trend is a threat to a healthy democracy. The aim of this paper attempts to show the important role of miranda and credenda of power in justification of power.
