T. M. Scanlon

T. M. Scanlon is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand T. M. Scanlon rather than just read about it. In short: Thomas Michael "Tim" Scanlon (; born June 28, 1940) is an American philosopher. At the time of his retirement in 2016, he was the Alford Professor of Natural Religion, Moral Philosophy, and Civil Polity in Harvard University's Department of Philosophy, where he had taught since 1984.

Key takeaways

  • T. M. Scanlon belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect T. M. Scanlon to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of T. M. Scanlon from memory before moving on to harder problems.

Reference excerpt

Thomas Michael "Tim" Scanlon (; born June 28, 1940) is an American philosopher. At the time of his retirement in 2016, he was the Alford Professor of Natural Religion, Moral Philosophy, and Civil Polity in Harvard University's Department of Philosophy, where he had taught since 1984. He was elected to the American Philosophical Society in 2018.

Life and career Scanlon was born on June 28, 1940, and grew up in Indianapolis, Indiana. He obtained his undergraduate degree from Princeton University in 1962; earned his PhD in philosophy from Harvard under Burton Dreben in 1968; studied for a year at Oxford University on a Fulbright Scholarship; and returned to Princeton, where he taught from 1966 until 1984. He was made a MacArthur Fellow in 1993. His teaching in the department has included courses on theories of justice, equality, and recent ethical theory. His book What We Owe to Each Other was published by Harvard University Press in 1998; a collection of papers on political theory, The Difficulty of Tolerance, was published by Cambridge University Press in 2003. Scanlon is the father-in-law of philosopher and African-American studies scholar Tommie Shelby.

Philosophical work Scanlon's dissertation and some of his first papers were in mathematical logic, where his main concern was in proof theory, but he turned to ethics and political philosophy, where he developed a version of contractualism in the line of John Rawls, Immanuel Kant, and Jean-Jacques Rousseau. Scanlon has also published important work on freedom of speech, equality, tolerance, foundations of contract law, human rights, conceptions of welfare, and theories of justice, as well as on foundational questions in moral theory.

Worked examples

Example 1 — a first encounter with T. M. Scanlon

Start with the simplest possible case. Write down what T. M. Scanlon claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to T. M. Scanlon before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about T. M. Scanlon ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of T. M. Scanlon

In research
T. M. Scanlon appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses T. M. Scanlon in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
T. M. Scanlon is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940 births, 20th-century American philosophers, 21st-century American philosophers, so understanding it makes those chapters shorter.
In everyday life
Look for T. M. Scanlon outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
