Głupota, ignorancja i acedia a poznanie intelektualne i działanie moralne

The aim of the article is to answer the question how the deficiencies and indisposition of intellectual cognition can influence the moral actions of a person. Three vices have been analyzed: stupidity, ignorance and acedia. The natural desire to know (Aristotle) is expressed in the transition from potency to act; consists in a natural inclination to perfect knowledge, realizing the perfection of human nature; it is fulfilled in the happiness that comes from passing from theoretical to practical knowledge, because knowledge cannot be something vain (vanus). In this context, it is clear that acedia blocks the transition of the potential intellect to any cognitive act. Ignorance explains why man does not acquire knowledge that could be used in moral acts, and therefore he does not realize his nature because of it. Ignorance is probably the best proof of the intellectual weakness of man's nature, its peculiar imperfection (internal resistance of the intellect). As for the practical order and the fulfillment of happiness in human action, it is best seen in contrast to the wisdom of stupidity. Lack of judgment in final matters (theoretical and practical) blocks the natural human disire for happiness
