Abstract
Nietzsche describes what is at the core of the concept of trust as it is used in agent societies and self-organising systems. Trust describes the expectation of one entity that the other behaves according to a set of rules. If that trust is broken, it is very hard to repair. If it exists, however, it is the basis of cooperation and enables a collective effort that gives a society purpose and allows it to succeed in its respective goals. Self-organisation is often at the root of such collective efforts as it allows the restructuring of a society to adapt to changing objectives, a changing environment, and new cooperation partners. Trust arises in such systems from the interactions of agents and the experiences of attempts to collaborate. It is thus only natural to regard trust and self-organisation together and explore the concepts' relation.
