The world as we know it does not exist — it exists only in our senses and somewhat in our thought. It is through an debasing of thought that the world exists. Animals must have a conception of the world as entirely different from our own, as ours from that of the high being to whom Evolution brings us.

The world, as it is, has no existence at all.

E.g. the idea of Space makes Space; it is not Space that makes the idea; it is not because there is Space that we have the idea of it, it is because we have the idea of Space that Space exists.
