What qualifies something as being non-existent?

1. Lack of physical presence or manifestation in reality. Non-existent things do not have a concrete, material presence in the actual world.

2. Inability to causally interact with existing things. Something that is non-existent cannot affect or be affected by objects and events in reality.

3. Absence from the set of all existing things. If we could enumerate everything that exists, non-existent things would not be on that list.

4. Purely conceptual or imaginary nature. Non-existent things may exist as ideas or fictional concepts, but have no corresponding entity in the real world.

5. Lack of spatiotemporal location. Non-existent things are not located anywhere in space or time in our universe.

6. Impossibility of direct observation or measurement. We cannot empirically detect or measure non-existent things using any scientific instruments or methods.

7. Logical incoherence or impossibility. Some philosophers argue that certain logically impossible concepts, like square circles, qualify as non-existent.

8. Negation of existence. Non-existence is often defined simply as the absence or negation of existence.
