Traps were set for more than one of us, and if we had walked into these traps our public careers would have ended, at least so far as following them under the conditions which alone make it worth while to be in public life at all. A man can of course hold public office, and many a man does hold public office, and lead a public career of a sort, even if there are other men who possess secrets about him which he cannot afford to have divulged. But no man can lead a public career really worth leading, no man can act with rugged independence in serious crises, nor strike at great abuses, nor afford to make powerful and unscrupulous foes, if he is himself vulnerable in his private character. Nor will clean conduct by itself enable a man to render good service. I have always been fond of Josh Billings's remark that "it is much easier to be a harmless dove than a wise serpent." There are plenty of decent legislators, and plenty of able legislators; but the blamelessness and the fighting edge are not always combined. Both qualities are necessary for the man who is to wage active battle against the powers that prey. He must be clean of life, so that he can laugh when his public or his private record is searched; and yet being clean of life will not avail him if he is either foolish or timid. He must walk warily and fearlessly, and while he should never brawl if he can avoid it, he must be ready to hit hard if the need arises. Let him remember, by the way, that the unforgivable crime is soft hitting. Do not hit at all if it can be avoided; but never hit softly. Like most young men in politics, I went through various oscillations of feeling before I "found myself." At one period I became so impressed with the virtue of complete independence that I proceeded to act on each case purely as I personally viewed it, without paying any heed to the principles and prejudices of others. The result was that I speedily and deservedly lost all power of accomplishing anything at all; and I thereby learned the invaluable lesson that in the practical activities of life no man can render the highest service unless he can act in combination with his fellows, which means a certain amount of give-and-take between him and them. Again, I at one period began to believe that I had a future before me, and that it behooved me to be very far-sighted and scan each action carefully with a view to its possible effect on that future. This speedily made me useless to the public and an object of aversion to myself; and I then made up my mind that I would try not to think of the future at all, but would proceed on the assumption that each office I held would be the last I ever should hold, and that I would confine myself to trying to do my work as well as possible while I held that office. I found that for me personally this was the only way in which I could either enjoy myself or render good service to the country, and I never afterwards deviated from this plan.
