Pasigraphy

Pasigraphy 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 Pasigraphy rather than just read about it. In short: A pasigraphy (from Greek πᾶσι pasi "to all" and γράφω grapho "to write") is a writing system where each written symbol represents a concept (rather than or not just a word or sound or series of sounds in a spoken language). The aim is to be intelligible to persons of all languages.

Key takeaways

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

Reference excerpt

A pasigraphy (from Greek πᾶσι pasi "to all" and γράφω grapho "to write") is a writing system where each written symbol represents a concept (rather than or not just a word or sound or series of sounds in a spoken language). The aim is to be intelligible to persons of all languages. The term was first applied to a system proposed in 1796, though a number of pasigraphies had been devised prior to that; Leopold Einstein reviews 60 attempts at creating an international auxiliary language, the majority of the 17th–18th century projects being pasigraphies of one kind or another, and several pasigraphies and auxiliary languages, including some sample texts, are also reviewed in Arika Okrent's book on constructed languages. Leibniz wrote about the alphabet of human thought and Alexander von Humboldt corresponded with Peter Stephen Du Ponceau who proposed a universal phonetic alphabet. Examples of pasigraphies include Blissymbols, Real Character, IConji and Yerkish.

Worked examples

Example 1 — a first encounter with Pasigraphy

Start with the simplest possible case. Write down what Pasigraphy 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 Pasigraphy 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 Pasigraphy 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 Pasigraphy

In research: Pasigraphy 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 Pasigraphy 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: Pasigraphy is common in secondary-school and first-year university syllabi. It links to neighbouring topics Interlinguistics, Writing system stubs, Writing systems, so understanding it makes those chapters shorter.
In everyday life: Look for Pasigraphy 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.

Frequently asked questions

What is Pasigraphy in simple terms?

Why does Pasigraphy matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Pasigraphy?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
