Now if any one should come in and hear you say, "Look at my lamp,"
what would he reply? He would most likely ask at once, "What lamp?"--for
there would be very little resemblance to a lamp in that mere ghost

But to you, who have seen the different parts removed one after another,
that wick soaked in oil (let your friend shake his head about it as
he pleases) will still be the lamp to you, however divested of much

consequence.

And this is exactly what happens when the machine we are discussing
is examined in the different grades of animals. The ignoramus who has
not followed it through its changes and reductions cannot recognize
it when it is presented to him in its lowest condition; but any one
who has carefully observed it throughout, knows that it is, in point
of fact, the same machine still.

This, then, is what we are now going to look at together, my dear
little girl. We will study first, piece by piece, the exquisite machine
within ourselves, which is of such unceasing use to us as long as we
do not give it more than a proper share of work to perform. Do you
understand? We will see what becomes of the mouthful of bread which
you place so coolly between your teeth, as if when that was done nothing
further remained to be thought about. We will trace it in its passage
through every part of the machine, from beginning to end. It will
therefore be simply only the _History of a Mouthful of Bread_ I
am telling you, even while I seem to be talking of other matters; for
