Open Classroom - Fall 2026

Three Dimensions of Philosophical Questioning

Philosophical questions rarely fit neatly into a single category. A question may concern what is real, how we know something, and what we ought to believe or do.

Explore questions from the classroom. Challenge their placement. Then contribute a philosophical question of your own.

Select a question below. Then click anywhere inside the triangle to propose a different placement.

Questions from the Classroom

These questions originated with students in the course. Their placement is open to challenge.

Questions from the Public

These questions were submitted by visitors to the project. A visitor's proposed placement is not necessarily the community's placement.

Ask Your Own Philosophical Question

What philosophical question has been bothering, intriguing, or puzzling you? Submit it here. You'll get to place it on the triangle yourself. If approved, your question will become part of the public philosophy project.

Your philosophical question

Why is this question significant? (optional, but encouraged)

Your name (optional)

Now place your question.

Click anywhere inside the triangle above. Think about whether your question is primarily metaphysical, epistemological, normative, or somewhere between them.

PHILOSOPHICAL ANSWERS

2. Respond to the Question

Answer

Use this space for your own answer to the philosophical question. Try to state what you think and give at least one reason for thinking it.

Good responses might begin with:

I think the answer is… My main reason is… An important distinction is… A possible objection is…

Keep this thread focused on answers. If you mainly want to reply to another visitor, debate a placement, or discuss the significance of the question, use Discuss the Debate below.

CONVERSATION & CRITIQUE

3. Discuss the Debate

Discuss

Use this space to engage with other people's reasoning rather than simply posting another standalone answer.

Discuss an answer Agree, disagree, ask for clarification, or raise an objection.

Discuss a placement Explain why a question seems more metaphysical, epistemological, normative, or mixed.

Discuss significance Say why the question matters, what assumptions it contains, or what follows from it.

A useful discussion post identifies what it is responding to. For example: “On the placement…”, “In response to the argument that…”, or “I agree with the answer, but…”.

How to Read the Triangle

The triangle does not divide philosophical questions into three rigid categories. Think of the corners as three poles within a larger philosophical space. A question can sit close to one corner or somewhere between two or all three.

Metaphysics

What exists? What is real? What are things fundamentally like?

Epistemology

What can we know? What should count as evidence? What makes a belief justified?

Normativity

What ought we believe? What ought we do? What gives us reasons?

Marker Key

1

Numbered circles (1–5)

Example classroom questions. Each number corresponds to one of the classroom examples listed below the triangle.

V1

Visitor markers (V1, V2, V3…)

Questions submitted by visitors and approved for this triangle. Each visitor question gets its own identifier—V1, V2, V3, and so on— and the same identifier appears on its question card. The marker shows that visitor's original proposed placement.

Faint shadow dots

Alternative placements proposed by other visitors. These are challenges to the original placement, not new questions.

C

Community center

When at least two placement challenges have been submitted, this marker shows the average location of those suggestions. It is a summary of the current challenge pattern, not a declaration that the community has reached philosophical agreement.

How to challenge a placement

1. Select a classroom or visitor question.
2. Choose Challenge This Placement in that question's interaction area.
3. Click a different location on the large triangle.
4. Briefly explain your reasoning if you wish, then choose Save Placement Challenge.

Once saved, your suggestion becomes one of the faint shadow dots for that question. The shadow-dot cloud is shown only for the question currently selected.

Which shadow dots belong to which question?

To avoid confusion, the final community view will show the shadow-dot scatter only for the question you currently have selected. When you select a different V question, the previous scatter disappears and the new question's challenge scatter appears around that question's original V marker.

The selected original marker will also be emphasized so it is always clear which question the visible shadow dots belong to.

If two or more challenges exist, a C marker shows the average challenge location. Its dashed halo gives a rough visual sense of how tightly or widely the suggestions are spread.
