"Ηθικά Νικομάχεια, Τόμος Πρώτος" by Aristotle is a philosophical work exploring the science of the good for human life. This foundational text asks how to best live, examining what all human actions ultimately aim toward. Consisting of ten books, it approaches ethics as practical rather than theoretical, seeking not just to understand goodness but to help people achieve it. The work profoundly influenced medieval philosophy and continues to shape modern ethical thought through its examination of virtue and the human good.
