Let us begin with a foundational question posed in one of the great dialogues of Western philosophy: What is knowledge? The inquiry into this question traverses centuries, starting with Plato’s dialogue Theaetetus. In this text, Plato grapples with the concept of knowledge, ultimately concluding that knowledge must encompass more than mere true belief. This critical insight invites us to consider the complexities surrounding belief and its relationship with reality. For Plato, true belief is insufficient if it lacks a solid grounding in justification; thus, a new definition of knowledge emerges: it is justified true belief.
Yet, as we dive deeper into our exploration, it is essential to acknowledge the challenges posed to this definition. In contemporary discussions, philosophers like Edmund Gettier have illustrated that there are scenarios where one can possess justified true belief without having what we would typically consider knowledge. These so-called “Gettier cases” reveal the possibility that our understanding of knowledge is yet incomplete. This leads us to ponder: Can we arrive at a final definition of knowledge, or is it, like many things in philosophy, an ever-evolving concept?
