Contrivances

3 2

Described in physical language the contrivance is
this. Take the twig a straw or a reed, between knot and knot of a tree, the straightest you
can find. Take hold of an end of it, and with
a finger of one of your hands — say the left
hand keep it fixt to the ground. While it is so fixt,
apply a finger of your right hand to the other end,
and keeping it gently turning round in one and
the same direction, till it has come back to the place
at which it was before you began to move it. If the
ground be smooth, and you have taken care that the
twig shall have pressed close upon the ground all the
time it has been thus moving, you will see a figure
traced on the ground a figure called a circle: the
spot on which you kept one end fixt with the finger of your
left hand is called the central point of the circle
or in one word the center: the mark line all round by
which marks the separation between that part of the ground
on which the twig pressed and that part to which it did
not extend is called the circumference

This circle thus described, now, with the same twig
one end of it fixt in the same place, describe another.
To make this other circle, take the other end of the twig
fix it with the finger of your left hand as before, leaving
the end that was first fixt (say the first end) loose. You
have thus another a second circle: the same in all its dimensions
with the first: for it is by the same twig that in the same
manner, with no other difference than that of having a different
end fixt, that it has been described. This second circle described
you will observe has points at which the two circles cut one, enter into
one
one another as it may
and occupies the same
portion of space: call
these the point of intersection.

Note on Text

You may in your mind put aside the consideration of the irregularities
in the twig as you have put aside the consideration of all
the properties on it but those which are designated by the word figure,
and thus you have the posological ideas.
But by putting aside these irregularities you do not cause the other physical
properties not to exist — you do not in the one case more than in the other:
your
your posological ideas
are therefore never any
thing more than your
physical ideas taken
each of them as separately
as possible from all others
from all those other physical ideas which are copies of impressions derived made on sense, or excerpts or compounds of those impressions.
