On purely practical grounds it is impossible to build up a national defence organization by means of private associations, unless the State makes an enormous contribution to it. Whoever thinks otherwise overestimates his own powers. Now it is entirely out of the question to form organizations of any military value for a definite purpose on the principle of so-called 'voluntary discipline'. Here the chief support for enforcing orders, namely, the power of inflicting punishment, is lacking. In the autumn, or rather in the spring, of 1919 it was still possible to raise 'volunteer corps', not only because most of the men who came forward at that time had been through the school of the old Army, but also because the kind of duty imposed there constrained the individual to absolute obedience at least for a definite period of time.
