ABSTRACT
This chapter considers an evaluation to be an axiological option, a mental construction, an arrangement, and a form. It introduces a theoretical framework based on a new concept of control. Central to this framework is a dialectical logic. The chapter speaks about processes to emphasize that a sequence of states or a dynamic system is involved. It shows that evaluations by synthesis can be described by a suitable structure, looking carefully at the operation of regression toward a constant. Roughly speaking, an evaluation and the set of all evaluations have the same structure, that is, constants and operations, subject to some laws, commutative or associative. The aim of pullback is to bring the new evaluations into intelligible relations with the old ones. Dynamic pullback strives for the maintenance of structural stability by establishing the equilibrium. A structural approach seems to be suitable for understanding management processes of human systems.
