Ethics and philosophy

Deduction and induction make different kinds of claim

Deduction asks what must follow from stated premises, while induction uses observations to suggest what may happen next. A valid deduction still needs true premises for a true conclusion; further observations can overturn an inductive generalization.

Can a disclosure be ethically defensible even when the law prohibits it?

A fictional employee believes the public needs to know about serious wrongdoing, but disclosure is legally restricted. The ethical question concerns the harm prevented, the harm caused, and the alternatives available. A legal accusation is a different kind of judgment; the U.S. government’s 2013 charges against Edward Snowden illustrate why an allegation should not be confused with a verdict.

Why keep a record of a rule's original purpose?

A workplace rule can look pointless after everyone forgets why it exists. A decision record can preserve the problem, alternatives, and reasoning for a future teammate. Compare that practical habit with Chesterton's fence analogy: understanding a barrier's purpose before deciding whether to remove it.

Who should answer for a harmful automated-vehicle decision?

In a fictional incident, an automated vehicle harms someone after a chain of decisions about design, testing, deployment, and supervision. Identifying the immediate cause does not by itself decide who should explain the failure or put it right. Legal liability is another question and requires the facts and law of a particular jurisdiction.

Could your memories prove that yesterday existed?

A diary and a memory both exist in the present, even when they refer to yesterday. Bertrand Russell’s five-minute-world thought experiment asks what would happen if a fictional alternative reproduced all that present evidence, without treating that alternative as a serious history of the world.

How can repeated exceptions make a warning sign seem normal?

A warning can start to feel routine when earlier incidents did not end in disaster. A NASA engineer’s retrospective on Columbia describes how previous foam strikes became a reason to discount concern, even though a safe landing had not demonstrated that the underlying problem was harmless.

A chair and its parts: the material and the object

Saw a wooden plank into four legs, a seat, and a backrest, and you have a pile of lumber; glue them together, and you have a chair. Something changes when those pieces are assembled, raising a classic philosophical puzzle about material constitution: is an object identical to the matter it is made of, or is it defined by its arrangement and function?

A donated sample can outlast its original research project

Research on a donated sample need not end with the first study. UK Biobank's consent and withdrawal arrangements show how a participant's choices, the institution's access decisions, and research already completed can fit together. Explore what continued use means for a donor's control.

Is the red you see the same red that I see?

We can agree that a tomato is red and choose the same matching paint. Does that agreement show that red feels the same to each of us? The puzzle separates what we can compare publicly from what another person’s experience is like.

What if alien civilizations were deliberately staying silent?

Liu Cixin's science-fiction novel The Dark Forest imagines civilizations hiding because contact could be dangerous. The idea offers a speculative response to cosmic silence, not an established explanation. Explore which assumptions make secrecy seem rational and whether observations could distinguish the story from competing possibilities.

A copied mind and two claims to the same identity

Suppose a futuristic scanner recorded the exact state of every neuron in your brain and built an identical digital copy of your mind on a computer. If the biological you woke up from the scan and looked at the screen, both of you would share the exact same childhood memories, personality, and habits, creating a sharp philosophical split between psychological continuity and physical identity.

How do I choose a topic?

Start with something you are curious about and consider what your audience would want to understand. You can narrow the collection by subject and suggested length. Those lengths are estimates, so check your timing as you develop and rehearse your speech.

What will I find on a topic page?

A short introduction, optional questions, and starting readings. You choose the focus and do the research. Save ideas to your free account, share a topic, or copy its reading notes. When you are ready, try a short practice in speaking.app.

How should I use the sources?

Each reading note describes what the linked material offers. Some readings are technical, and some provide only an abstract or overview. Check the original source, its context, and any claims you plan to use. A starting reading list is not an exhaustive review of a subject.
