According to Zagrebelsky, law has a dual soul: legal judgment always incorporates evaluations of material justice and thus does not exhaust itself in the application of legislative formulas. Those evaluations are not prejudices or influences to be avoided, but essential components of what is to be understood by law, and as such must be cultivated openly, restoring the authentic dualist structure of law. This dualism is reflected par excellence in the judicial use of the Constitution, where the material justice component of law is evident. The judge is therefore not - and should not be - the pure technician of the laws, but a responsible person to the culture of his time.
