Open this path →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 this object →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 this object →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 this object →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 this object →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 this object →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.

Enter the journey“A changed answer may reveal which fact carried the moral weight.”
Change one fact
Would your answer change?
Your earlier choice: Do not read a private message.
What changed: You now have a specific, credible reason to believe someone faces immediate harm.
Continue with privacy, moral responsibility.
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.
Enter this thought experiment →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.
Enter this thought experiment →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.
Enter this thought experiment →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.
Enter this thought experiment →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.
Enter this thought experiment →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.

Ethics in Everyday Life
This path begins with familiar choices and gradually introduces privacy, truthfulness, consequences, duties, and responsibility without requiring allegiance to one ethical theory.
Follow this learning path →Self, Memory, and Identity
This path explores how bodies, memories, records, narratives, relationships, and continuing projects contribute to the sense that one person persists through change.
Follow this learning path →Minds, Machines, and Technology
This path separates useful performance, computation, understanding, consciousness, knowledge, and responsibility while connecting philosophical arguments with present-day AI use.
