      §8. Thus a Company of Chess-men, standing on the same squares
of the Chess-board, where we left them, we say they are all in the
same Place, or unmoved; though, perhaps, the Chess-board hath
been in the mean time carried out of one Room into another,
because we compared them only to the Parts of the Chess-board,
which keep the same distance one with another. The Chess-board,
we also say, is in the same Place it was, if it remain in the same part of
the Cabin, though, perhaps, the Ship which it is in, sails all the
— 170 —
while: and the Ship is said to be in the same Place, supposing it kept
the same distance with the Parts of the neighbouring Land; though,
perhaps, the Earth hath turned round; and so both Chess-men, and
Board, and Ship, have every one changed Place in respect of remoter
Bodies, which have kept the same distance one with another. But
yet the distance from certain Parts of the Board, being that which
determines the Place of the Chess-men; and the distance from the
fixed parts of the Cabin (with which we made the Comparison)
being that which determined the Place of the Chess-board, and the
fixed parts of the Earth, that by which we determined the Place of
the Ship, these things may be said properly to be in the same Place,
in those respects: Though their distance from some other things,
which in this matter we did not consider, being varied, they have
undoubtedly changed Place in that respect; and we our selves shall
think so, when we have occasion to compare them with those
other.
