that praxeology is a science that is broader than the science of work as it contains philosophical elaboration of the concept of action, especially in the context of human work process, including the recommendations and general solutions for human activities in different fields. His position is considered partially descriptive in the sense that its aim is to understand relevant features of actions, but that the classifications it produces have normative objectives. Kotarbiński's contribution to the understanding of the nature of action is considered foundational for action theory (philosophy) Three years after publishing A Treatise on Good Work, Kotarbiński persuaded the Polish Academy of Sciences to establish a Laboratory for General Questions of Work Organization (Pracownia Ogólnych Problemów Organizacji Pracy), later upgraded into a Department of Praxeology. Starting in 1962, it published a periodical, Materiały Prakseologiczne (Praxeological Papers), later renamed Prakseologia (Praxeology).
