Las Virtudes Fundamentales by Josef Pieper

A concise, philosophically grounded exploration of the four cardinal virtues—prudence, justice, fortitude and temperance—tracing their Aristotelian-Thomistic roots and showing how they function as stable dispositions that order reason and desire toward the human good. The work emphasizes prudence as the formative virtue guiding concrete moral choices, treats justice as giving others their due, and presents fortitude and temperance as the virtues that steady courage and moderate appetite, arguing that these fundamental virtues are the foundation of moral life and human flourishing when integrated with contemplative insight.
