Before it was my sensations that changed; now it is the house itself.
We are drawing this distinction between changes in our sensations and changes in things at every hour in the day.

I cannot move without making things appear and disappear.

If I wag my head, the furniture seems to dance, and I regard it as a mere seeming.

I count on the clock's going when I no longer look upon its face.

It would be absurd to hold that the distinction is a mere blunder, and has no foundation in our experience.
