Imagine two different games both played with chess men on a chess
board.
The initial positions of both are alike.
One of the games is always played with red and green pieces, the
other with black and white.
Two people are beginning to play, they have the chess board between
them with the red and green
165.
pieces in position.
Someone asks them, “Do you know what game
you're intending to play?”
A player answers, “Of course; we are playing
No.2.”
“What is the difference now between playing
no.2 and no.1?” ‒ ‒
“Well, there are red and green pieces on the board and not
black and white ones, also we say that we are playing
no.2.” ‒ ‒
“But this couldn't be the only difference;
don't you
understand what
‘no.2’ means and what game the red and
green pieces stand for?”
Here we are inclined to say, “Certainly I do”
and to prove this to ourselves we actually begin to move the pieces
according to the rules of game no.2.
This is what I should call moving in the immediate surrounding of our
initial position.
