(*) Compare _Hinterlassene Werke_, 2nd edition. vol. vii. p. 193 _et seq_. In this case the means of comparison lie much more on the surface than in the foregoing, but they have been equally overlooked, because one-sided views have prevailed, and there has been no freedom of judgment. From the necessity of pointing out a better means which might have been used in place of those which are condemned has arisen the form of criticism almost exclusively in use, which contents itself with pointing out the better means without demonstrating in what the superiority consists. The consequence is that some are not convinced, that others start up and do the same thing, and that thus discussion arises which is without any fixed basis for the argument. Military literature abounds with matter of this sort. The demonstration we require is always necessary when the superiority of the means propounded is not so evident as to leave no room for doubt, and it consists in the examination of each of the means on its own merits, and then of its comparison with the object desired. When once the thing is traced back to a simple truth, controversy must cease, or at all events a new result is obtained, whilst by the other plan the _pros_ and _cons_ go on for ever consuming each other. Should we, for example, not rest content with assertion in the case before mentioned, and wish to prove that the persistent pursuit of Blücher would have been more advantageous than the turning on Schwartzenberg, we should support the arguments on the following simple truths: 1. In general it is more advantageous to continue our blows in one and the same direction, because there is a loss of time in striking in different directions; and at a point where the moral power is already shaken by considerable losses there is the more reason to expect fresh successes, therefore in that way no part of the preponderance already gained is left idle. 2. Because Blücher, although weaker than Schwartzenberg, was, on account of his enterprising spirit, the more important adversary; in him, therefore, lay the centre of attraction which drew the others along in the same direction. 3. Because the losses which Blücher had sustained almost amounted to a defeat, which gave Buonaparte such a preponderance over him as to make his retreat to the Rhine almost certain, and at the same time no reserves of any consequence awaited him there.
