Because of its power to siphon emotion out of distinct ideas, the symbol is both a mechanism of solidarity, and a mechanism of exploitation. It enables people to work for a common end, but just because the few who are strategically placed must choose the concrete objectives, the symbol is also an instrument by which a few can fatten on many, deflect criticism, and seduce men into facing agony for objects they do not understand.
Many aspects of our subjection to symbols are not flattering if we choose to think of ourselves as realistic, self-sufficient, and self-governing personalities. Yet it is impossible to conclude that symbols are altogether instruments of the devil. In the realm of science and contemplation they are undoubtedly the tempter himself. But in the world of action they may be beneficent, and are sometimes a necessity. The necessity is often imagined, the peril manufactured. But when quick results are imperative, the manipulation of masses through symbols may be the only quick way of having a critical thing done. It is often more important to act than to understand. It is sometimes true that the action would fail if everyone understood it. There are many affairs which cannot wait for a referendum or endure publicity, and there are times, during war for example, when a nation, an army, and even its commanders must trust strategy to a very few minds; when two conflicting opinions, though one happens to be right, are more perilous than one opinion which is wrong. The wrong opinion may have bad results, but the two opinions may entail disaster by dissolving unity. [Footnote: Captain Peter S. Wright, Assistant Secretary of the Supreme War Council, _At the Supreme War Council,_ is well worth careful reading on secrecy and unity of command, even though in respect to the allied leaders he wages a passionate polemic.]
Thus Foch and Sir Henry Wilson, who foresaw the impending disaster to Cough's army, as a consequence of the divided and scattered reserves, nevertheless kept their opinions well within a small circle, knowing that even the risk of a smashing defeat was less certainly destructive, than would have been an excited debate in the newspapers. For what matters most under the kind of tension which prevailed in March, 1918, is less the rightness of a particular move than the unbroken expectation as to the source of command. Had Foch "gone to the people" he might have won the debate, but long before he could have won it, the armies which he was to command would have dissolved. For the spectacle of a row on Olympus is diverting and destructive.
