What does it mean to not exist? Philosophers have debated for centuries the nature of existence, but have any ever thought about nonexistence? I'm sure some have but I'm not a philosopher student so I know none off the top of my head.
Some people want to believe that to die is to slip into nonexistence. But they do still exist don't they? The body still exists in some form or another until nature finishes recycling it. Memories and records of their life would still exist for a while too. Is that enough to still be in existences? How exclusive is this nonexistence? What does it take to get passed the bouncer at the door?
Because if all it takes is a single thought in a single mind to say that something exists, then for something to not exist every mind in the universe would have to not think about it for all eternity.
And if existence means physically being there, then my thoughts don't exist. And if my thoughts don't exist do I? Does the disruption of physical matter by nonphysical sources, such as thought, count as physically existing? Prime example of what I mean: Sound is just the disruption of air molecules. Is that disruption then a physical existence? Because if it is not than spoken language doesn't exist right along with my thoughts.
