Plato’s Allegory of the Cave and Theory of Ideas
Plato’s Allegory of the Cave
Prisoners and Shadows
The prisoners, chained within a cave since childhood, represent individuals trapped in the sensible world.

The Principle of Causality and Uniformity of Nature
The principle of causality, stating that every effect has a cause and vice versa, relies on experience and our belief in the uniformity of natural phenomena.
