Introduction

Philosophy is the systematic examination of fundamental questions concerning reality, knowledge, reason, mind, and value. Unlike disciplines that rely on empirical data collection or laboratory experimentation, philosophy operates through conceptual analysis, logical deduction, thought experiments, and disciplined argument evaluation. Studying philosophy trains you to identify unexamined assumptions, detect fallacious reasoning, and articulate complex positions with precision.

This curriculum is designed for self-directed learners starting from scratch, with no prior formal background assumed. It provides a lean, rigorous foundation covering the central historical traditions, logical tools, and systematic subfields that define an undergraduate education in philosophy.

This core does not attempt to cover the entire discipline. Advanced subfields, specialized methodologies, and technical concentrations (such as modal logic, decision theory, philosophy of science, and critical theory) are reserved for Advanced Topics. To engage directly with primary source literature, refer to Readings; to explore structured lecture series, consult Courses; and to apply these methods through independent writing and argument analysis, visit Projects.

The subjects are sequenced intentionally into three progressive phases, moving from basic reasoning mechanics to historical frameworks and systematic questions:

Communities

Curriculum

Introduction to Philosophy

Surveys foundational questions regarding reality, knowledge, consciousness, personal identity, and the examined life.

Introduction to Philosophy: Logic (Open Textbook Library / Rebus Community) - An open-access introductory reader that reinforces argument analysis, fallacy detection, and the transition toward formal methods; designed to be read alongside Talbot's lectures.

Formal Logic

Introduces formal deductive systems, symbolic propositional logic, truth tables, natural deduction proofs, and basic first-order predicate calculus.

forall x: An Introduction to Formal Logic (P.D. Magnus) - A standard open-access textbook covering truth-functional propositional logic, formal semantics, and natural deduction proofs.

Logic I (MIT OpenCourseWare / Jack Spencer) - A complete university-level introductory formal logic course providing lecture handouts, problem sets, and exams; complements the forall x text with structured exercises.

Ancient Greek Philosophy

Examines the origins of Western philosophy in classical Greece, centering on the Presocratics, Socrates, Plato, and Aristotle.

Readings in Ancient Greek Philosophy: From Thales to Aristotle (S. Marc Cohen, Patricia Curd, & C.D.C. Reeve, eds. / Hackett Publishing) - The canonical undergraduate survey anthology containing primary translations, introductory overviews, and explanatory notes from the Milesians through Aristotle.

The Internet Classics Archive (MIT) - A free public-domain collection providing direct access to Benjamin Jowett's translations of Plato's dialogues (including the Apology, Crito, Meno, and Republic) and Aristotle's major treatises; an open alternative to commercial anthologies.

Ancient Philosophy (MIT OpenCourseWare / Sally Haslanger) - A structured course framework with syllabi, reading schedules, and lecture notes covering early Greek metaphysics, epistemology, and virtue theory.

A History of Philosophy: Lectures 1 to 24 (Wheaton College / Arthur Holmes) - An in-depth recorded classroom lecture series tracing Western thought chronologically from Thales to Hellenistic philosophy; use as a sequential narrative lecture companion to the primary readings.

Early Modern Philosophy

Studies the profound philosophical revolution from Descartes through Kant, focusing on the debates between rationalism and empiricism concerning knowledge, substance, and causation.

Modern Philosophy: An Anthology of Primary Sources (Roger Ariew & Eric Watkins, eds. / Hackett Publishing) - The standard academic collection containing the primary texts of Descartes, Spinoza, Leibniz, Locke, Berkeley, Hume, and Kant.

Early Modern Texts (Jonathan Bennett) - A freely accessible repository featuring modern-spelling, lightly annotated editions of essential early modern works designed to make historical syntax and terminology accessible to self-taught readers.

General Philosophy (University of Oxford Podcasts / Peter Millican) - An eight-week introductory lecture series tracing modern epistemology and metaphysics through Descartes, Locke, Berkeley, and Hume.

A History of Philosophy: Lectures 32 to 54 (Wheaton College / Arthur Holmes) - Builds on Holmes's ancient series, providing exhaustive historical lectures covering the continental rationalists, British empiricists, and the Kantian critical philosophy.

Epistemology

Investigates the nature, sources, and scope of knowledge, justified belief, perception, skepticism, and the analysis of truth.

Knowledge: A Very Short Introduction (Jennifer Nagel / Oxford University Press) - A concise, lucid introduction to the foundational concepts of epistemology, including Gettier problems, skepticism, reliabilism, and contextualism.

Theory of Knowledge (MIT OpenCourseWare / Declan Smithies) - A structured university syllabus with reading lists, paper topics, and lecture handouts examining skepticism, perceptual justification, and responses to Moore and Descartes; best studied after reading Nagel.

Metaphysics

Investigates the fundamental structure of reality, including existence, universals, substance, causation, time, persistence, and modal necessity.

Metaphysics: An Introduction (Alyssa Ney / Routledge) - A comprehensive, rigorous introductory textbook covering contemporary ontology, persistence through time, mind-body physicalism, causation, and possible worlds.

Reality Bites: Introduction to Metaphysics (Coursera / Erasmus University Rotterdam / Tim De Mey) - A structured, free-to-audit video course that introduces core metaphysical puzzles—such as universals, substance, persistence, and composition—using intuitive analogies; ideal to take concurrently with Ney's textbook.

Ethics

Analyzes moral theory and normativity, focusing on metaethics, the three major normative frameworks (utilitarianism, deontology, and virtue ethics), and applied ethical problems.

The Fundamentals of Ethics (Russ Shafer-Landau / Oxford University Press) - The most widely assigned undergraduate ethics textbook, notable for its clear reconstructive arguments evaluating hedonism, utilitarianism, Kantian ethics, social contract theory, and moral realism.

Justice with Michael Sandel (Harvard University) - A full-semester Harvard video course introducing moral and political philosophy by confronting students with classic dilemmas and theoretical critiques from Aristotle, Kant, and Mill; serves as an engaging audio-visual counterpart to Shafer-Landau.
