Enter an interactive journey →Investigate a philosophical question
Start with a lasting question about meaning, truth, identity, privacy, or responsibility and compare several defensible ways of answering it.
Explore philosophy questions →Ordinary objects, hidden questions
Begin with something familiar.
The Smartphone
A smartphone is not only a convenient tool. It is also a private archive, an attention-shaping environment, a social gateway, and a record of choices. Thinking carefully about how we use, share, and design smartphones reveals tensions among privacy, autonomy, consent, identity, and responsibility.
Examine The Smartphone →The Philosophy of a Photograph
A photograph records a visible moment while also selecting, framing, preserving, and circulating it, making one image carry questions about truth, memory, identity, and care.
Examine The Philosophy of a Photograph →The Philosophy of Money
Money is a practical medium of exchange and a social institution that coordinates strangers, stores claims, measures prices, and can reshape how people compare unlike goods.
Examine The Philosophy of Money →The Philosophy of a Mirror
A mirror returns a present appearance with unusual immediacy, yet what a person learns from it depends on optics, expectations, social meanings, and the larger story of a changing self.
Examine The Philosophy of a Mirror →The Philosophy of a Gift
A gift appears to be a freely given transfer, yet its meaning often depends on relationship, intention, acceptance, gratitude, reciprocity, and expectations that may remain unstated.
Examine The Philosophy of a Gift →The Philosophy of a Clock
A clock divides duration into shared units that coordinate action, but measured time is not identical with the passage, urgency, patience, or significance people experience.

The Borrowed Phone
A message preview appears while you are using a friend's phone for one specific purpose. Decide how far the permission extends, then reconsider when the risk becomes clearer.

The strongest objection we did not want to hear
When a polarized dispute invites us to judge an argument by its speaker, intellectual courage begins with hearing the strongest objection on each side before deciding.

Building Quickly Without Knowing Every Consequence
Fast building is not automatically reckless, nor is caution automatically responsible. When consequences remain uncertain, the ethical question becomes whether experimentation is bounded by serious inquiry, meaningful oversight, correction, and repair.

Emergency powers after the emergency
A reported plan to continue the Washington, D.C., National Guard mission through January 2029 raises a question that outlasts the immediate dispute: what should happen when an emergency measure becomes a durable institution? Plato, Locke, Kant, Mill, and Rawls offer different tests of necessity, autonomy, liberty, and.

Read this reflection →A short reasoning exercise
Change one fact. See what carries the weight.
Begin with a clear situation and a provisional rule. Then add one new fact and choose what you would do. The point is not to earn a score; it is to notice which reason becomes decisive and what your choice costs.
1. Starting situation
You have a friend's phone for one limited task.
Your friend lends you their unlocked phone only so you can send yourself a photograph. A private message preview appears, but its wording is ambiguous and your friend is not in the room.
Your starting position: Do not read the private message. The permission covered the photograph, not the conversation.
2. Change only this fact
The possible danger becomes specific and immediate.
A second preview gives you a specific, credible reason to believe someone faces immediate harm. Your friend still cannot be found.
Given that new information, what would you do?
Classic thought experiments
Change the setting. Keep the question.
The Ship of Theseus
The Ship of Theseus asks whether an object remains the same when all its parts are gradually replaced. A second version of the puzzle imagines the discarded parts being rebuilt into another ship, forcing us to compare material, structural, historical, functional, and practical accounts of identity.
Explore The Ship of Theseus →The Experience Machine
The Experience Machine asks whether you would exchange life in the ordinary world for perfectly convincing experiences of achievement, love, pleasure, and meaning.
Explore The Experience Machine →The Veil of Ignorance
The Veil of Ignorance asks people to choose principles for society without knowing which social position, abilities, aims, or generation they will occupy.
Explore The Veil of Ignorance →The Chinese Room
The Chinese Room imagines a person producing perfect Chinese responses by following formal rules while understanding no Chinese, challenging the claim that computation alone is sufficient for understanding.
Explore The Chinese Room →The Trolley Problem
A runaway trolley forces a choice between allowing five people to be struck and redirecting the danger toward one person, exposing conflicts among harm, rights, agency, and outcomes.
Explore The Trolley Problem →The Prisoner’s Dilemma
The Prisoner’s Dilemma models a situation in which each person has a reason to defect whatever the other does, even though mutual cooperation would leave both better off.

This path explores how bodies, memories, records, narratives, relationships, and continuing projects contribute to the sense that one person persists through change.
Start Self, Memory, and Identity →Minds, Machines, and Technology
