Plato

In this book of philosophy, the writer dwells on the idea of justice and an ideal state. He does that through a set of dialogues on what the society is, what the philosopher-king does, and how a republic, in an ideal setting, should be crafted. The work also introduces the notion of reality, which includes the theory of the Forms and the famous allegory of the cave. It shakes the readers on the reflection of the core truth, governance, and the way the soul gets enlightened. This timeless piece encourages deep thought on how societies should be organized and governed for the greater good.
