Ontological maximalism

Ontological maximalism is a physics 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 Ontological maximalism rather than just read about it. In short: In philosophy, ontological maximalism (or metaontological maximalism) is a ontological realist position that asserts, "whatever can exist does in some sense exist". Overview Meta-ontology deals with question related to ontology, whether there are mind independent (objective) answers to "what exists".

Key takeaways

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

Reference excerpt

In philosophy, ontological maximalism (or metaontological maximalism) is a ontological realist position that asserts, "whatever can exist does in some sense exist".

Overview Meta-ontology deals with question related to ontology, whether there are mind independent (objective) answers to "what exists". Ontological realism asserts that reality (at least a part of it) is independent of the human mind. In contrast to realists, ontological anti-realists deny that the world is mind-independent. Believing the epistemological and semantic problems to be insoluble, they conclude that realism must be false. Maximalism is one of two main metaontological positions. In a maximalist framework, any entity whose existence is consistent with the nature of this world can be taken to exist.

Worked examples

Example 1 — a first encounter with Ontological maximalism

Start with the simplest possible case. Write down what Ontological maximalism 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 Ontological maximalism 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 Ontological maximalism 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 Ontological maximalism

In research: Ontological maximalism 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 Ontological maximalism 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: Ontological maximalism is common in secondary-school and first-year university syllabi. It links to neighbouring topics Metaphysics stubs, Ontology, Set theory, so understanding it makes those chapters shorter.
In everyday life: Look for Ontological maximalism 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 Ontological maximalism in simple terms?

In philosophy, ontological maximalism (or metaontological maximalism) is a ontological realist position that asserts, "whatever can exist does in some sense exist". Overview Meta-ontology deals with question related to ontology, whether there are mind independent (objective) answers to "what exists…

Why does Ontological maximalism matter?

Because it connects several physics 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 Ontological maximalism?

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.
