AbstractIt starts in a simple question and purpose of what is fair in the transport chain concept, and develops to an abductive reasoning based on critical business ethics research and polyphonic narratives for an understanding of the mess that involves people, ethics in supply chains, interest organizations and EU institutions. Analytical understanding arrives from the Spinozian ethical principles in societies, justice and mercy. Justice as a social pact in order to escape the natural injustice and inequality outside the social system. Mercy as recognizing individuals in collective co-existence. Fairness in fair transport is suggested to be of a dynamic nature and derived from knowledgeable reasoning and found in lived ethico-political relationships.
