In Rebus Vagueness: The World’s Indeterminacy

Understanding In Rebus Vagueness

In rebus vagueness, also known as ontic vagueness, is a philosophical perspective that suggests indeterminacy is a fundamental characteristic of reality itself. This means that the world, independent of our minds or language, can be vague.

Key Concepts

The core idea is that certain phenomena or objects in the world do not possess sharply defined boundaries or properties. This is not due to our inability to describe them precisely, but because they are genuinely indeterminate.

Contrast with Other Views

• Epistemic Vagueness: This view holds that vagueness arises from limitations in our knowledge. The world is precise, but we don’t know enough to pinpoint exact boundaries.
• Semantic Vagueness: This perspective attributes vagueness to the meanings of words in our language. Vagueness exists because our linguistic terms are inherently imprecise.

Deep Dive into Ontic Vagueness

Proponents of in rebus vagueness argue that concepts like ‘heap’ or ‘tall’ might reflect genuine fuzziness in the objects or categories themselves. For instance, a collection of grains might be neither clearly a heap nor clearly not a heap, and this indeterminacy is a feature of the collection itself.

Implications and Applications

This view has implications for metaphysics, philosophy of language, and even scientific modeling. It challenges the traditional assumption of a sharply defined reality and suggests that our models might need to accommodate inherent indeterminacy.

Challenges and Misconceptions

A common challenge is to provide a coherent account of how such objective vagueness can exist. Critics often question whether apparent vagueness is truly in rebus or if it can always be traced back to linguistic or epistemic factors. The idea is often misunderstood as simply admitting ignorance.
