Lecture: What Philosophy Is: Socrates and the Examined Life
Lecture script · about 15–20 minutes spoken · Week 1
Opening
Think about the last time you heard someone say, "That isn't fair." Maybe it was a roommate arguing about a shared bill. Maybe it was a coworker talking about a new schedule. Maybe it was you. In almost every case, the people arguing agree on the facts. What they disagree about is what the word "fair" means.
Whether you're a nursing student asking what consent to treatment really requires, a business major reading a company's idea of a fair bonus, or a juror weighing what counts as reasonable doubt, the first step is the same. You ask what a word means, and you test the answer with one honest case. That habit is where philosophy starts.
This is the first week of the course, so we begin at the foundation. In this lecture I'll tell you what philosophy is and lay out its six main branches. Then we'll meet Socrates through his trial, read one line from Plato's Apology, and learn the method that carries his name. We'll finish with how to read an old text in translation. Next, in Week 2, Arguments and Thought Experiments, we'll give that questioning a fixed shape so you can judge whether an argument works.
1. What philosophy is
Picture three roommates and one electric bill of 90 dollars a month. Two of them want to split it evenly, 30 dollars each. The third works nights, is rarely home, and says that isn't fair. They could ask the landlord to decide. They could let the oldest roommate pick. Either way the argument ends, but nobody learns what's fair.
To learn that, somebody has to give a reason, and the others have to test it. That's the difference between deciding a question and examining it. Philosophy is the examination of fundamental questions about reality, knowledge, mind, value, and reasoning by careful argument rather than by appeal to authority alone.
Let me unpack that sentence, because every piece of it does work. Fundamental questions are the ones other questions rest on, like what makes an act right, or what it means to know something. Careful argument means reasons other people can check. And "rather than by appeal to authority alone" means "because I said so" never ends the conversation. An expert's view can be a good reason. In philosophy, you still ask why the expert holds it.
Here's a fair worry you might have. Philosophers disagree a lot, and some questions stay open for a very long time. Doesn't that make it all opinion? It doesn't. Disagreement is not the same as every answer being equal. Some reasons rest on a mistake. Some definitions fall apart the first time you test them. A view backed by reasons that survive testing is better supported than a view backed by none.
I'll make you one promise about this course. It will never tell you which answer to an open question is correct. It will show you the strongest reasons on each side, and it will ask you to argue for a view of your own.
Pause and try this. The landlord tells the roommates, "Split it evenly." Is that philosophy? Why or why not?
Think about whether any reason got tested.
Here's the answer. No, it isn't, because the landlord settled the question by authority, and nobody's reason was put on the table to be checked. If one roommate said, "We all chose to share the place, so we share its costs," and another answered back, that would be philosophy starting.
2. The six branches
Now picture a hospital break room at the end of a long shift. One nurse wonders whether the person in bed 4 truly understood the consent form. Another wonders whether the hospital's new visiting rule treats families with justice. A third asks whether a painting in the lobby is art or decoration. Those are three different kinds of question.
Philosophy sorts its questions into branches, and this course uses six. Let me give you each one with one question it asks.
Metaphysics is the branch that asks what exists and what it is like. Epistemology asks what we can know and when a belief is justified. Ethics asks how we should live and what makes an act right or wrong. Logic asks what makes reasoning good, and how to tell good reasoning from bad. Political philosophy asks what justice is and what makes a state or government legitimate. And aesthetics asks what beauty is and what makes something a work of art.
That's 6 branches. Here's a quick way to hold them. Metaphysics is about what's there, and epistemology is about what you can know of it. Ethics is about how to act, and logic is about how to reason. Political philosophy is about living together under rules, and aesthetics is about beauty and art.
Here's the part students often miss. Real questions don't stay on one shelf. The nurse's question about consent is mainly epistemology, because it asks whether someone knew something. But it has an ethics side, because consent matters morally. So when you sort a question, name its home branch, and then say what other branch it touches.
Pause and try this. Which branch is home to the third nurse's question, whether the lobby painting is art or decoration?
Listen to what the question is really about.
Here's the answer. It's aesthetics, because it asks what makes something a work of art. It could touch other branches, but the main thing being asked is about art itself.
3. Socrates and his trial
Imagine a courtroom in Athens where a man is on trial for the way he questions people. That's the first case on this course's thought-experiment roster, the trial of Socrates. It's a historical case, not an invented one. The course opens with it because it asks why anyone would spend a life asking questions.
Here are the facts the course relies on, and I want you to have them exactly. Socrates was tried in Athens in 399 BCE, convicted of impiety and of corrupting the young, and put to death by drinking hemlock. BCE means before the Common Era, so those years count backward toward year 1.
Now for a twist that matters for everything you'll read about him. Socrates wrote nothing that survives. What we know of his views comes mainly from his students, above all Plato's dialogues. A dialogue here is a written conversation, and most of Plato's dialogues have Socrates as the main speaker. So when this course says "Socrates says," it means "Socrates, as Plato writes him."
Think of it like a famous coach who never wrote a book. Everything you know about the coach's ideas comes from a former player who wrote about them years later. You'd trust the player a lot. You'd still remember whose pen it was.
The trial also hands you the roster's question: is a life spent questioning worth the risk? The case tests why philosophy examines beliefs at all, even when examining them makes people angry. The course takes no side on that question. Your job is to ask it well.
Pause and try this. A classmate writes, "In his dialogue the Apology, Socrates argues…" What needs fixing?
Think about who held the pen.
Here's the answer. Socrates didn't write the Apology; Plato did. Socrates wrote nothing that survives, so the fix is to credit Plato as the author and Socrates as the speaker: "In Plato's Apology, Socrates argues…"
4. The pinned line and its translator
The Apology is Socrates' defense speech at his trial. In this title, "apology" means a defense, not saying sorry. In it, Socrates speaks to the jury about the life he has led. In Benjamin Jowett's translation, he says that "the unexamined life is not worth living" while explaining why he will not stop questioning people. This course calls that line Q1, the first of its pinned quotations, and it's the only line from the Apology we quote word for word.
Now I want you to slow down on who is standing behind those words, because there's more than one person there. First there's the speaker, Socrates, who spoke at his trial and wrote nothing down. Then there's the author, Plato, who wrote the Apology. Then there's the translator, Benjamin Jowett, who put Plato's text into English. That's 1 speaker, plus 1 author, plus 1 translator, which makes 3 people between the event and your English page.
So whose English words are these? They're Jowett's. Socrates never spoke these English words. When the course writes "trans." after a quotation, short for "translated by," the name that follows tells you whose English you're reading. A translation is a version of a text in another language, and in a translated quotation the words on the page belong to the translator, who is named, not to the original author.
It's a little like hearing a song covered by another singer. The song came from someone else, but the voice you're hearing is the cover artist's. You'd name both.
Pause and try this. Someone posts, "Socrates wrote, 'the unexamined life is not worth living.'" Name two mistakes in that sentence.
Count the people behind the line.
Here's the answer. First, Socrates wrote nothing, so "wrote" is wrong; Plato wrote the Apology, and Socrates is its speaker. Second, the English words are Jowett's, so the post should name him as the translator.
5. The Socratic method
Back to the roommates. Suppose one of them says, "Fairness means everyone pays the same." How would Socrates answer? He wouldn't shout, and he wouldn't call a vote. He'd ask for a case. Is there a situation where everyone gets the same and it still seems unfair?
That's the Socratic method: a way of examining a belief by asking for a definition, testing it with a counterexample, revising it, and testing the revision again. A definition is a statement of what a word means, meant to fit every case the word covers and no case it does not. And a counterexample is a case that a definition gets wrong. One clear counterexample is enough to show that a definition, as stated, needs revising.
Let's run it on a group project with 4 members. This is an illustrative case, not a real group. Round 1: the first definition, D1, says fairness means everyone gets exactly the same. Here's the test. Say 1 member did none of the work, yet all 4 receive the same credit. Most people would call that unfair. So D1 counts an unfair case as fair, and it fails as stated.
Round 2: we revise. The new definition, D2, says fairness means each person gets what they have earned. Here's the test. One teammate who is hard of hearing gets captions on the group's video calls, and the other 3 don't. Nobody earned the captions, yet most people would call providing them fair. So D2 leaves out a fair case, and it fails as stated too.
That's 2 definitions tested and 2 counterexamples found, so 2 rounds of questioning. And notice where we end up. We don't have a settled definition. We have a sharper question, and we know two things fairness is not. That's real progress.
Here's a handy way to read a counterexample. D1 was too broad, because it let in a case that isn't fair. D2 was too narrow, because it left out a case that is fair. Asking "too broad or too narrow?" tells you what the counterexample has shown.
One more thing. A counterexample does not prove the opposite of the definition. If "fairness means sameness" fails, that doesn't mean fairness means difference. It means you revise and test again, which is why the method has rounds. And it works on ideas, not on people. The goal is a better definition everyone can share, not a point scored against a friend.
Pause and try this. Was the counterexample to D1 a sign that D1 was too broad, or too narrow?
Ask whether D1 let something in or left something out.
Here's the answer. Too broad, because D1 counted the group-project case as fair, and most people would call it unfair. It let in a case it should have kept out.
6. Reading a primary text in translation
A primary text is a work by the philosopher or source being studied, such as Plato's Apology, rather than a later summary or explanation of it. Reading one isn't like reading a news story. The text is old, it wasn't written in English, and the person speaking may not be the person who wrote it.
You already have what you need to handle that. I'll give you four moves for any short passage. First, find the claim: what is the speaker saying is true, or should be done? Second, say who wrote the words on the page, and whether the speaker is also the author. Third, name the translator, so you know whose English you're reading. Fourth, end in one plain sentence that says the claim in your own words.
Let's run the four moves on Q1. The claim is that a life without examination is not worth living. The author is Plato, and the speaker is Socrates. The translator is Benjamin Jowett. And here's one plain sentence: in Plato's Apology, Socrates tells the jury that a life without examination is not worth living, and the words "the unexamined life is not worth living" are Jowett's English for that line.
Listen to how that sentence handles quotation marks. The summary part has none. Only Jowett's exact words go inside them. That's the course's rule: only the pinned quotations appear in quotation marks, word for word, with the translator named. Everything else is a paraphrase, and you mark it as one, with words like "Socrates argues that."
Pause and try this. Of the four moves, which one tells you whose English words you're reading?
It's one of the middle two.
Here's the answer. The third move, naming the translator, because in a translated text the English words on the page belong to the translator.
Closing
Let me pull it together. Philosophy examines fundamental questions by careful argument, not by authority alone, and disagreement doesn't make every answer equal. Its six branches are metaphysics, epistemology, ethics, logic, political philosophy, and aesthetics, and real questions often touch more than one. Socrates was tried in Athens in 399 BCE and put to death by drinking hemlock, and you read him through Plato because he wrote nothing that survives. Q1 is Jowett's English for what Socrates says in Plato's Apology. The Socratic method asks for a definition and tests it with a counterexample, round after round. And reading a primary text means finding the claim, the author, and the translator, then saying it plainly.
Next in this module come the slide deck, the Readings and Resources page, the lecture tutorial, the practice set, and the quiz. Then, in Week 2, Arguments and Thought Experiments, you'll learn to write an argument's reasons on numbered lines above its conclusion, so you can judge whether the reasoning works.
