ent of the compositors' hands, and
determine the subsequent results of every impress of the type on paper;
one mind thus, by directing the labour of others, imparting the quality
of much wealth or of little or of none, to every one of the ten thousand
copies of which the edition is composed.
Similarly when a man invents, and brings into practical use, some new
and successful apparatus such, let us say, as the telephone, the same
situation repeats itself. The new apparatus is an addition to the
world's wealth, not because so many scraps of wood, brass, nickel,
vulcanite, and such and such lengths of wire are shaped, stretched, and
connected with sufficient manual dexterity--for the highest dexterity is
very often employed in the making of contrivances which turn out to be
futile--but because each of its parts is fashioned in obedience to
certain designs with which this dexterity, as such, has nothing at all
to do. The apparatus is successful, and an addition to the world's
wealth, because the designs of the inventor, just like the author's
manuscript, constitute a multitude of injunctions proceeding from a
master-mind, which is not the mind of those by whose hands they are
carried into execution.
And with the direction of labour generally, whether in the production of
machinery or the use of the machinery in the production of goods for the
public, the case is again the same. We have manual labour of a given
kind and quality, which assists in producing what is wanted or not
wanted--what is so much wealth or simply so much refuse, in accordance
with the manner in which all this labour is directed by faculties
specifically different from those exercised by the manual labourers
themselves.
And now we are in a position to sum up in a brief and decisive formula
what the difference between the sets of faculties thus contrasted is. It
is not essentially a difference between lower and higher, for some forms
of labour, such as that of the great painter, may be morally higher than
some forms of direction. The difference is one not of degree, but of
kind, and includes two different psycho-physical processes. Labour, from
the most ordinary up to the rarest kind, _is the mind or the brain of
one man affecting that man's own hands_, and the single task on which
his hands happen to be engaged. The directive faculties are _the mind or
the brain of one man simultaneously affecting the hands of any number of
other men_, and through t
