required, you will be summoned."

When he left me, I still felt very weary, and lay down on a little couch
in the room, falling presently asleep. I was roused by the entry of a
young man, who said he had been sent to fetch me: we went down along the
passages, while he talked pleasantly in low tones about the arrangements
of the place. As we went along the passages, the doors of the cells kept
opening, and we were joined by young men and women, who spoke to me or
to each other, but all in the same subdued voices, till at last we
entered a big, bare, arched room, lit by high windows, with rows of
seats, and a great desk or pulpit at the end. I looked round me in great
curiosity. There must have been several hundred people present, sitting
in rows. There was a murmur of talk over the hall, till a bell suddenly
sounded somewhere in the castle, a door opened, a man stepped quickly
into the pulpit, and began to speak in a very clear and distinct tone.

The discourse--and all the other discourses to which I listened in the
place--was of a psychological kind, dealing entirely with the relations
of human beings with each other, and the effect and interplay of
emotions. It was extremely scientific, but couched in the simplest
phraseology, and made many things clear to me which had formerly been
obscure. There is nothing in the world so bewildering as the selective
instinct of humanity, the reasons which draw people to each other, the
attractive power of similarity and dissimilarity, the effects of class
and caste, the abrupt approaches of passion, the influence of the body
on the soul and of the soul on the body. It came upon me with a shock of
surprise that while these things are the most serious realities in the
world, and undoubtedly more important than any other thing, little
attempt is made by humanity to unravel or classify them. I cannot here
enter into the details of these instructions, which indeed would be
unintelligible, but they showed me at first what I had not at all
apprehended, namely the proportionate importance and unimportance of all
the passions and emotions which regulate our relations with other souls.
These discourses were given at regular intervals, and much of our time
was spent in discussing together or working out in solitude the details
of psychological problems, which we did with the exactness of chemical
analysis.

What I soon came to understand was that the whole of psychology is
