"Our universe, as we experience it . . . is a conceit of our mode of perception". I leave it quite open that there may be a lot to it we can't see at all with our mode of perception.

You could place youself as the center of, and sole motivator of, the universe - that it's all your own perception and there's nothing outside of your perception, but this seems not to work well. If that were so, people would probably not be harassing you so much, would they?

It appears what we have is a consensus perception with a great many different and different kinds of entities contributing to its construction and maintenance.

Different types of entities may perceive the same universe quite differently, but those of near types seem to have a similar perception.
