Order and Chaos

Chime in that, an absence can certainly be defined as a concept, which makes it at least some manner of thing, doesn't it?

But in order to explore the nature of nothing in greater detail, it could help to set up a point of comparison to measure it against. Take, for example, our reality. The present we sense and interact with. Something we can certainly conceptualize and experience. And we can compare that to something else... the past. Something we can no longer experience or influence, but which we can identify as a concept. Isn't that some manner of Thing made of Nothing? That is to say, if our only access to the past is via a series of memories of supposed events, isn't the past just a series of things that no longer are? A sum of our non-existences? As far as our present and real selves can tell, the present is all that is. It's possible that you merely have some illusory memory of past, fabricated by a lying mind. Mere moments ago, it's possible that nothing actually existed! That existence was null and void!

And yet, you'd still claim it existed, no?
