Is Philosophy Just Opinions?

"Isn't philosophy just a bunch of questions without answers? Why waste your time?"

I hear some version of that question often enough that it's worth taking seriously. If philosophy really is opinion-trading dressed up in long words, then yes — go do something else with your afternoon. But I don't think it is, and I want to walk through why.

The classic "gotcha" examples usually miss the point

In high school I was taught that medieval theologians used to spend their time arguing about how many angels could dance on the head of a pin. The example is supposed to make philosophy look ridiculous: even granting that angels exist, how could anyone possibly know the answer?

Here's the thing — nobody actually asked that question expecting a number. You could ask it rhetorically to make a real metaphysical point: that things with location but no extension can be co-located. The pin is just a vivid way to picture the claim.

The same goes for one of philosophy's more famous puzzles: how do we know the universe didn't pop into existence a moment ago, fully equipped with our memories and historical records? Surely that's something we can't know — so why bother asking?

Again, the question isn't asked for an answer. It's asked to make a structural point: we don't actually have certitude about anything in the past. And that turns out to matter a lot.

Lack of certainty doesn't make a field worthless

If you can't be certain about the past, you can't be certain about science either — science depends entirely on past observations being reliable guides to the future. But we still trust science. And we should.

Here's why this matters: if we threw out every inquiry that doesn't deliver perfect certainty, we'd have to stop eating. Any given bite could be the poisonous one — you can't prove otherwise from your past meals — so by that standard, dinner is irrational. Obviously, nobody reasons that way. Most of what we believe is held with more or less confidence, only a small handful of things with total certainty, and we live our lives anyway.

Philosophy operates in that same space. It's not a defect of the discipline; it's the human condition.

Everyone already does philosophy

Now for the bigger claim. Do you have any opinion about what we should and shouldn't do? About what is and isn't real? About what we can and can't know?

If yes — congratulations, you're a philosopher. You have philosophical positions on ethics, metaphysics, and epistemology, whether you've ever called them that or not.

So the question isn't whether you do philosophy. You already do. The question is whether you do it well. And without any training, most of us do it pretty poorly — holding strong views we've never tested, that quietly contradict our other views, that fall apart under the lightest pressure.

That's what philosophy as a discipline actually is. Not the manufacture of opinions out of thin air, but the careful examination of the opinions we already hold.

Let's talk

I think the best philosophy happens in dialogue, so I'd genuinely like to hear from you in the comments. Two prompts to chew on:

What beliefs do you think are the most important to hold? Are those beliefs certain? Is there any way to doubt them?

And — granting for the sake of argument that we never really know anything in philosophy — what are some other things we routinely discuss, decide on, and act on without being certain about them?
