Also F. H. Bradley, Appearance and Reality, p. 346:

"My external sensations are no less private to myself than are my
thoughts or my feelings. In either case my experience falls within
my own circle, a circle closed on the outside; and, with all its
elements alike, every sphere is opaque to the others which surround
it. . . . In brief, regarded as an existence which appears in a soul,
the whole world for each is peculiar and private to that soul."

'que vos guida al som de l'escalina,
'sovegna vos a temps de ma dolor.'
Poi s'ascose nel foco che gli affina."
