Teleonomic entropy is a measure of disorder in biopsychosocial systems. How this disorder will be distributed over parts and levels in these systems depends on the kind and strength of the corresponding interaction, which in turn is closely related to the hierarchical ordering in these multilevel systems and their purposes and goals In particular, it is argued that teleonomic entropy is transferable, that is, teleonomic entropy at a given level of a given system can affect the teleonomic entropy of another system at the same level (transference), or of different levels of the same system or other systems (transformation) The identification of purposes with the system's structure, i.e., generalized structures including dynamic ones, establishes an interdisciplinary link and provides a common language among various disciplines. The goals are related to the interaction with the environment, the system's attempts to utilize its resources.
