Reference excerpt

On the Content and Object of Presentations (German: Zur Lehre vom Inhalt und Gegenstand der Vorstellungen, "On the Doctrine of the Content and Object of Presentations") is an 1894 book by the Polish philosopher Kazimierz Twardowski, a student of the philosopher Franz Brentano.

Reception The philosopher Reinhardt Grossmann has observed that On the Content and Object of Presentations greatly influenced the course of philosophy. The philosopher Alexius Meinong adopted Twardowski's distinction between the individual mental act, its content and its object, and his contention that there are many objects of acts that do not exist. This helped Meinong to clearly separate presentations from the objects which they intend.

Worked examples

Example 1 — a first encounter with On the Content and Object of Presentations

Start with the simplest possible case. Write down what On the Content and Object of Presentations claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 On the Content and Object of Presentations 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 On the Content and Object of Presentations 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 On the Content and Object of Presentations

In research: On the Content and Object of Presentations appears in physics 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 On the Content and Object of Presentations 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: On the Content and Object of Presentations is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1894 non-fiction books, Books by Kazimierz Twardowski, Metaphysics of mind, so understanding it makes those chapters shorter.
In everyday life: Look for On the Content and Object of Presentations 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.
