Summary

This is the first lecture of an epistemology course by Professor Marco Ruffino (UNICAMP). The lecture introduces the fundamental questions of epistemology, focusing on the nature of knowledge. It begins by referencing Plato’s Theaetetus, where Socrates attempts to define knowledge, leading to an aporia. The lecture then outlines the traditional tripartite analysis of knowledge as justified true belief, explaining the roles of belief, truth, and justification. Ruffino discusses how philosophers like Descartes focused on justification, and how the Gettier problem in the 20th century challenged the sufficiency of justified true belief. The lecture concludes by presenting two responses to Gettier: skepticism or refining the notion of epistemic justification. The content is accessible yet rigorous, providing a solid foundation for further study.
