almost invisible train of logical subtleties. If, adhering closely to
the absolute, we try to avoid all difficulties by a stroke of the pen,
and insist with logical strictness that in every case the extreme must
be the object, and the utmost effort must be exerted in that direction,
such a stroke of the pen would be a mere paper law, not by any means
adapted to the real world.

Even supposing this extreme tension of forces was an absolute which
could easily be ascertained, still we must admit that the human mind
would hardly submit itself to this kind of logical chimera. There
would be in many cases an unnecessary waste of power, which would be in
opposition to other principles of statecraft; an effort of Will would
be required disproportioned to the proposed object, which therefore it
would be impossible to realise, for the human will does not derive its
impulse from logical subtleties.

But everything takes a different shape when we pass from abstractions to
reality. In the former, everything must be subject to optimism, and we
must imagine the one side as well as the other striving after perfection
and even attaining it. Will this ever take place in reality? It will if,

(1) War becomes a completely isolated act, which arises suddenly, and is
in no way connected with the previous history of the combatant States.

(2) If it is limited to a single solution, or to several simultaneous
solutions.

(3) If it contains within itself the solution perfect and complete,
free from any reaction upon it, through a calculation beforehand of the
political situation which will follow from it.
