In all this, of course, I strip the process of its plumes and spangles, and expose a chain of causes and effects that Roosevelt himself, if he were alive, would denounce as grossly contumelious to his native purity of spirit--and perhaps in all honesty. It is not necessary to raise any doubts as to that honesty. No one who has given any study to the developement and propagation of political doctrine in the United States can have failed to notice how the belief in issues among politicians tends to run in exact ratio to the popularity of those issues. Let the populace begin suddenly to swallow a new panacea or to take fright at a new bugaboo, and almost instantly nine-tenths of the master-minds of politics begin to believe that the panacea is a sure cure for all the malaises of, the republic, and the bugaboo an immediate and unbearable menace to all law, order and domestic tranquillity. At the bottom of this singular intellectual resilience, of course, there is a good deal of hard calculation; a man must keep up with the procession of crazes, or his day is swiftly done. But in it there are also considerations a good deal more subtle, and maybe less discreditable. For one thing, a man devoted professionally to patriotism and the wisdom of the fathers is very apt to come to a resigned sort of acquiescence in all the doctrinaire rubbish that lies beneath the national scheme of things--to believe, let us say, if not that the plain people are gifted with an infallible sagacity, then at least that they have an inalienable right to see their follies executed. Poll-parroting nonsense as a matter of daily routine, the politician ends by assuming that it is sense, even though he doesn't believe it. For another thing, there is the contagion of mob enthusiasm--a much underestimated murrain. We all saw what it could do during the war--college professors taking their tune from the yellow journals, the rev. clergy performing in the pulpit like so many Liberty Loan orators in five-cent moving-picture houses, hysteria grown epidemic like the influenza. No man is so remote and arctic that he is wholly safe from that contamination; it explains many extravagant phenomena of a democratic society; in particular, it explains why the mob leader is so often a victim to his mob.
