through the fingers of physiology, she must hold fast to the
considerations suggested by our unconscious states. As far, however,
as the investigations of the pure physicist are concerned, the
unconscious and matter are one and the same thing, and the physiology
of the unconscious is no "philosophy of the unconscious."

By far the greater number of our movements are the result of long and
arduous practice. The harmonious cooperation of the separate
muscles, the finely adjusted measure of participation which each
contributes to the working of the whole, must, as a rule, have been
laboriously acquired, in respect of most of the movements that are
necessary in order to effect it. How long does it not take each note
to find its way from the eyes to the fingers of one who is beginning
to learn the pianoforte; and, on the other hand, what an astonishing
performance is the playing of the professional pianist. The sight of
each note occasions the corresponding movement of the fingers with
the speed of thought--a hurried glance at the page of music before
him suffices to give rise to a whole series of harmonies; nay, when a
melody has been long practised, it can be played even while the
player's attention is being given to something of a perfectly
different character over and above his music.

The will need now no longer wend its way to each individual finger
before the desired movements can be extorted from it; no longer now
does a sustained attention keep watch over the movements of each
limb; the will need exercise a supervising control only. At the word
of command the muscles become active, with a due regard to time and
proportion, and go on working, so long as they are bidden to keep in
their accustomed groove, while a slight hint on the part of the will,
will indicate to them their further journey. How could all this be
