What are the best online resources for learning about philosophy?

Absolutely. Philosophy is one of the easiest subjects to study online because some excellent university-level material is freely available.

My top recommendations

1. Stanford Encyclopedia of Philosophy (SEP) — best reference

   • Probably the single best starting point when you want to understand a philosopher, argument, or philosophical concept.
   • Entries are written and maintained by specialists and reviewed by an editorial board.
   • Excellent for questions like “What is utilitarianism?”, “What did Kant mean by the categorical imperative?”, or “What are the arguments for free will?”
   • Level: Intermediate → advanced.

2. Internet Encyclopedia of Philosophy — best for approachable explanations

   • Free, scholarly articles on philosophers and topics, written by professional philosophers and peer-reviewed.
   • I often recommend it before SEP because its explanations can be a little more approachable.
   • Level: Beginner → advanced.

3. Open Yale Courses: Philosophy — best for taking actual courses

   • Yale provides free lectures and course materials, with no registration required.
   • Particularly good is Philosophy and the Science of Human Nature, which connects philosophers such as Plato, Aristotle, Hobbes, Kant, Mill, Rawls, and Nozick with contemporary cognitive science.
   • Level: Beginner → intermediate.

4. Open Yale Courses: Death — excellent example of philosophy in action

   • Shelly Kagan's course tackles questions about personal identity, mortality, immortality, suicide, and how awareness of death should affect how we live.
   • It's particularly good if you learn better by following a sustained philosophical investigation rather than reading encyclopedia entries.

5. Class Central's philosophy course guide — best for discovering courses

   • A useful directory if you want to explore many different online courses. Its current guide catalogs 150+ free philosophy courses, including offerings from Yale, MIT, Georgetown, and the Open University.

If you're starting from zero

I'd use this sequence:

1. Take a course → 2. Read the primary texts → 3. Use SEP/IEP to clarify difficult ideas → 4. Write your own arguments.

For example:

Yale course on philosophy → Plato's Apology → SEP article on Socrates/Plato → write: “Was Socrates right to refuse to stop philosophizing?”

That last step is important. Philosophy isn't primarily about memorizing what famous philosophers said; it's about learning to construct, analyze, and criticize arguments.

A good progression

If you tell me what kind of philosophy interests you—e.g. meaning of life, ethics, free will, consciousness, God, politics, Stoicism, existentialism, or ancient philosophy—I can give you a free, structured 4–8 week philosophy curriculum with readings and lectures.

Whether you are a complete beginner or looking to dive deep into specialized theories, the internet offers world-class resources for studying philosophy.

Community Perspectives

“I usually start with the relevant Stanford Encyclopedia of Philosophy article, however the SEP is aimed at academics and can often be challenging for beginners. If the SEP article is not what you're looking for, the other links are usually much more...”

“Professional philosophy can seem abstract, esoteric, and hyper-specialized. But we all ask and try to answer philosophical questions myriad times daily—philosophy is the purview not just of the expert, but of all thoughtful people.”

If you'd like to narrow these down, tell me:

• Are you looking for a specific subfield (like ethics, political philosophy, or logic)?
• Do you prefer reading short essays, listening to audio , or following a structured course?

Absolutely. If you’re learning philosophy on your own, I’d combine structured courses, reliable reference works, and actual primary texts rather than relying on YouTube summaries alone.

Best resources

1. Stanford Encyclopedia of Philosophy (SEP) — best overall reference

   • Probably the single best online philosophy reference.
   • Articles are written by academic philosophers and cover philosophers, arguments, movements, and specific problems in considerable depth.
   • Best once you have a basic grasp of the subject.
   • Use it for: “What exactly is Kant's categorical imperative?” or “What are the arguments for and against free will?”

2. Internet Encyclopedia of Philosophy (IEP) — best for beginners

   • Free, scholarly, and generally more approachable than the SEP.
   • It has 900+ articles written by professional philosophers and reviewed through an academic editorial process.
   • Use it for: getting oriented before tackling more difficult sources.

3. Open Yale Courses — best free university lectures

   • Yale's free philosophy courses include video/audio lectures, transcripts, syllabi, readings, and sometimes problem sets.
   • A particularly good starting point is PHIL 181: Philosophy and the Science of Human Nature, taught by Tamar Gendler.
   • Use it for: learning philosophy as an actual course rather than jumping randomly between topics.

4. 1000-Word Philosophy — best quick introductions

   • Short, accessible essays on philosophical questions and thinkers.
   • Particularly useful when you're encountering a concept for the first time and don't want to read a 30-page academic article.
   • Philosophy learners on Reddit frequently recommend it alongside SEP and IEP.

5. Wireless Philosophy (Wi-Phi) — best for visual learners

   • Short animated videos explaining philosophical arguments, logic, ethics, epistemology, and related topics.
   • Good as an introduction before reading the harder material.

6. Internet Classics Archive / Project Gutenberg — best for reading the philosophers themselves

   • Once you've learned the basic vocabulary, go to the primary sources: Plato, Aristotle, Descartes, Hume, Kant, Mill, Nietzsche, etc.
   • Don't substitute summaries for the original works indefinitely. Philosophy is largely about learning to follow an argument firsthand.

If you're starting from zero

I'd go in this order:

Open Yale lecture → IEP/1000-Word Philosophy → primary text → SEP for deeper questions

For example, if you want to learn Plato:

introductory lecture → IEP article on Plato → Apology → Republic → SEP articles on Plato's specific arguments

That approach prevents the common problem of reading a philosopher's difficult text without knowing what problem they're actually trying to solve.

A particularly good learning path

If your goal is to develop a solid general foundation, I'd study roughly:

1. Logic & argumentation
→ 2. Socrates & Plato
→ 3. Aristotle
→ 4. Descartes & early modern philosophy
→ 5. Hume
→ 6. Kant
→ 7. Nietzsche
→ 8. Existentialism
→ 9. Ethics
→ 10. Political philosophy
→ 11. Philosophy of mind & consciousness
→ 12. Epistemology & philosophy of science

You don't need to read everything. The important skill is learning to ask: What is the claim? What reasons support it? What assumptions does it depend on? What would count against it?

If you tell me whether you're a complete beginner, somewhat familiar, or already well-read, I can also give you a free 8–12 week philosophy curriculum with specific lectures, books, and readings for each week.

If you're looking for high-quality philosophy resources, the best approach is to combine a few different formats: reference works for accuracy, courses for structure, videos for intuition, and podcasts for ongoing exploration.

Here's a curated list:

Learning the Hard Stuff

“The Internet Encyclopedia of Philosophy is a great resource for relatively accessible descriptions. The Stanford Encyclopedia of Philosophy is more detailed, but also more technical and less accessible.”

• Do you have a specific era or topic in mind (e.g., Ancient Greek, Ethics, Existentialism)?
