It is one of his best servants, one of the noblest of God's gifts to
him. Without the thumb three-fourths (at least) of human arts would
yet have to be invented; and to begin with, the art not only of carrying
the contents of one's plate to one's mouth, but of filling the plate
(a very important question in another way) would, but for the thumb,
have had difficulties to surmount of which you can form no idea.

Have you noticed that when you want to take hold of anything (a piece
of bread, we will say, as we are on the subject of eating), have you
noticed that it is always the thumb who puts himself forward, and that
he is always on one side by himself, whilst the rest of the fingers
are on the other? If the thumb is not helping, nothing remains in your
hand, and you don't know what to do with it. Try, by way of experiment,
to carry your spoon to your mouth without putting your thumb to it,
and you will see what a long time it will take you to get through a
poor little plateful of broth. The thumb is placed in such a manner
on your hand that it can face each of the other fingers one after
another, or all together, as you please; and by this we are enabled
to grasp, as if with a pair of pincers, whatever object, whether large
or small. Our hands owe their perfection of usefulness to this happy
arrangement, which has been bestowed on no other animal, except the
monkey, our nearest neighbor.

I may even add, while we are about it, that it is this which
distinguishes the hand from a paw or a foot. Our feet, which have other
things to do than to pick up apples or lay hold of a fork, our feet
have also each five fingers, but the largest cannot face the others;
it is not a thumb, therefore, and it is because of this that our feet
are not hands. Now the monkey has thumbs on the four members
corresponding to our arms and legs, and thus we may say that he has
