Abstract
The author sets a goal to show the specificity of the formulation of universal prescriptive judgments about a virtuous act in the framework of Aristotelian ethical doctrine. To achieve this goal, Aristotle’s philosophy concept of practical wisdom is analyzed. It shows a necessity to distinguish the use of practical wisdom in a personal experience of the act and for forming the inter-subjective practical knowledge about making of a virtuous act. The specificity of ethics as practical knowledge and its difference from individual moral experience are defined by means of the distinction of the use of practical wisdom. It also shows the limitations of practical syllogism as the main rational mechanism for the formation of inter-subjective practical knowledge. Additionally, the universal prescriptive judgments are divided into informative and functional: the former reveals the content of the action, the latter – its structure, that is, the former defines what a person must do, the latter defines what an action should be to comply with the right purpose, consequently, the right content. At the same time, the right content is recognized only in individual experience and can not be expressed universally, without losing its practical value. The author concludes that the formulation of informative universal prescriptive judgments is impossible within the framework of Aristotelian ethical doctrine. It is impeded by the unsolvable problem of the correlation between the general and the particular, the transition from descriptive judgments to prescriptive judgments. However, it is possible to formulate functional universal prescriptive judgments. They also constitute the methodological basis for criticism of the accepted in society moral norms, which are based on the past positive experience of actions.
