to have a castle in Spain when one possesses the money to pay for it.

It is the complexity of modern life which enforces moderation. Science
has created vast populations and huge industries, and also given the
means by which single minds can direct them. Invention gives these
gifts, and compels man to use them. Man is as much the slave as the
master of the machine, as he turns to the telephone or the telegram. In
this fierce turmoil of the modern world he can only keep his judgment
intact, his nerves sound, and his mind secure by the process of
self-discipline, which may be equally defined as restraint, control, or
moderation. This is the price which must be paid for the gifts the gods
confer.

Many serious letters and a half-humorous criticism in _Punch_ suggest
that I am to be regarded as the apostle of a pure materialism. That is
not so. I quite recognise the existence of other ambitions in the walks
of Art, Religion, or Literature. But at the very outset I confined the
scope of my advice to those who wish to triumph in practical affairs. I
am talking to the young men who want to succeed in business and to build
up a new nation. Criticism based on any other conception of my purpose
is a spent shaft.
