Skepticism and certainty

This lesson focuses on skepticism and certainty. Interdisciplinary approaches reveal connections that single-subject study might miss.

Philosophy explores fundamental questions about knowledge, ethics, and existence. Epistemology (theory of knowledge): How do we know what we know? Sources: Rationalism (reason and logic—Plato, Descartes), Empiricism (sensory experience—Locke, Hume). Skepticism questions whether we can have certain knowledge; Descartes' "I think, therefore I am" is the most foundational certain statement. Ethical relativism holds that moral standards are culturally determined—no universal right or wrong. Moral objectivism holds that some moral claims are universally true regardless of cultural norms. Ethical dilemmas pit competing values against each other; most real moral challenges don't have clear answers but require weighing competing obligations. Character ethics (virtue ethics) emphasizes that consistent good actions build virtuous character; character is revealed especially under pressure. Personal values guide decision-making; examining your values explicitly helps align actions with intentions. Civic ethics: obligations to the community, future generations, and the political process. Global ethics: environmental stewardship, human rights, global justice cross national boundaries and require international frameworks.

As you engage with this material, consider both the theoretical foundations and practical applications. Think critically about how this concept builds on prior knowledge and where you might apply it beyond the classroom.

Challenge yourself to go beyond memorization—seek to understand the "why" behind the processes and principles.
