Remarks on the definitions of main concepts of logic of action
The article presents the definitions of action and of its omission, formulated in some logical theories of action. The concern of the analysis is to point at manifold possibilities of precising the intuitive sense of discussed concepts depending on the theory. The utility of a particular definition may be evaluated when the domain of applicability of the theory is taken into account ; application often becomes justification for the choice of a given definition.
