Abstract
The intelectual virtue of discernment occupies a privileged position in Aristotle’s ethics, since it intervenes in judging and choosing the best option regarding our voluntary actions. As for the Stoics, the virtues are cognitions and can be reduced to only one. The person who possesses that unique virtue is called a ‘sage’ and is able to choose, for himself, the right action to reach happiness. Thus, we propose to discover if the Stoic sage can be compared to the prudent man in Aristotle by examining some key ethical issues of theses philosophical schools. We conclude that the similar theses exceed the different ones, despite encountering a quite distinct vocabulary which deceives at first sight.
