If we rise into larger fields, we shall find more notable demonstration of the starving effect of the entertainment of a single idea. Scattered throughout the country we shall find men who have devoted themselves to the cause of temperance, or abstinence from intoxicating liquors. Here is a grand, a humane, a most worthy and important cause; yet temperance as an idea is not enough to furnish food for a human soul. Some of these men have only room in them for one idea, and, so far as they are concerned, it might as well be temperance as any thing, though it is bad for the cause; but the majority of them were, at starting, men of generous instincts, a quick sense of that which is pure and true, and a genuine love of mankind. They dwelt upon their idea--they lived upon it for a few years--and then they "showed their keeping." If I should wish to find a narrow-minded, uncharitable, bigoted soul, in the smallest possible space of time, I would look among those who have made temperance the specialty of their lives--not because temperance is bad, but because one idea is bad; and the men afflicted by this particular idea are numerous and notorious. They have no faith in any man who does not believe exactly as they do. They accuse every man of unworthy motives who opposes them. They permit no liberty of individual judgment and no range of opinion; and when they get a chance, they drive legislation into the most absurd and harmful extremes. Men of one idea are always extremists, and extremists are always nuisances. I might truthfully add that an extremist is never a man of sound mind.
