Yes, I was thinking about your post with the mirage as I was writing.
It seems to me that people tend to think that first a thing was real, then it was percieved and became real as a concept to us aswell. People seem to assume that everything begins with physical existence, and that consciousness is secondary. Never mind the fact that many things that have physical reality started out as ideas in consciousness.
As I see it, a statment that would perhaps describe reality in a better way for us might be; reality is a state of consciousness that exists as a tangled hierarchical process.
It assumes, of course, that reality is, at it's most fundamental level, consciousness rather than physical.
The oposite is generally regarded as truth, but it is also merely an assumption. It also leaves us wanting answers to how consciousness came to be and where it came from.
