Critical Identitarian Justice of Otherness would seem to be the form of justice that best guarantees dimensions of otherness, care, freedom, identity, peace, hope and dignity. This type of justice, presupposed on an ethical ground represented by tunefully comprehensive ethics, could constitute a valid theoretical reference in order to address the challenges posed by post-complexity in a more coherent way. Post-complex disintegrity, in fact, would seem to be transfigured thanks to a precise ethical and justice dimension, which is well summarized by the moral characteristics identified in this work.
