Lost in the Cosmos

Lost in the Cosmos is a science 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 Lost in the Cosmos rather than just read about it. In short: Lost in the Cosmos: The Last Self-Help Book is a mock self-help book by Walker Percy, published in 1983 by Farrar Straus & Giroux. Organized into roughly four sections that explore ideas of the self, Percy's thesis is that the social ills which plague society are a result of humanity's epic identity crisis.

Key takeaways

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

Reference excerpt

Lost in the Cosmos: The Last Self-Help Book is a mock self-help book by Walker Percy, published in 1983 by Farrar Straus & Giroux. Organized into roughly four sections that explore ideas of the self, Percy's thesis is that the social ills which plague society are a result of humanity's epic identity crisis. Percy uses semiotic theories (the theories of signs) to argue that human consciousness of the self is unique from all other 'interactions' in the universe in that it is triadic. It requires two sets of dyadic interactions between that of the sign user, the sign, and what the sign stands for in order to be complete. As a result, persons are thrust into the predicament of finding a sign that 'places' themselves. The book contains numerous essays, quizzes, and "thought experiments" designed to satirize conventional self-help texts while provoking readers to undertake a thoughtful contemplation of their existential situations and the search for meaning and purpose that could derive from such reflections.

Reception According to Andrew Hoogheem, it is:

easily Walker Percy's strangest book. On its surface a darkly humorous parody of the literature of self-help, this late work… runs the reader down a gauntlet of multiple-choice questions… whose cumulative effect is to leave her more bereft of answers than when she began. Along the way it conjures up dialogues between talk show hosts and long-dead theologians, inveigles its readers into seriously contemplating suicide, shoulders in on the debates of academic semioticians, presents an overview of world history that predicts World War III erupting as a consequence of Western anomie, and arrives at its denouement by way of… science fiction stories of nuclear war and alien encounters.

The book is a favorite of the philosopher Peter Kreeft, of Boston College, and a lecture on the subject appears on his personal website.

Worked examples

Example 1 — a first encounter with Lost in the Cosmos

Start with the simplest possible case. Write down what Lost in the Cosmos claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Lost in the Cosmos 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 Lost in the Cosmos 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 Lost in the Cosmos

In research
Lost in the Cosmos appears in science 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 Lost in the Cosmos 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
Lost in the Cosmos is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1983 non-fiction books, Books by Walker Percy, Cognitive science literature, so understanding it makes those chapters shorter.
In everyday life
Look for Lost in the Cosmos 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.
