This points to the contrast to which I have referred: the contrast between the keen vigorous good sense upon immediate questions of the day, to which I often listen with the unfeigned admiration due to the shrewd man of business, and the paltry little outworn platitudes which he introduces when he wants to tag his arguments with sounding principles. I think, to take an example out of harm's way, that an excellent instance is found in the famous American treatise, the _Federalist_. It deserves all the credit it has won so long as the authors are discussing the right way to form a constitution which may satisfy the wants and appease the prejudices then actually existing. In spite of such miscalculations as beset all forecasts of the future, they show admirable good sense and clear appreciation. But when they think it necessary to appeal to Montesquieu, to tag their arguments from common sense with little ornamental formulæ learnt from philosophical writings, they show a very amiable simplicity; but they also seem to me to sink at once to the level of a clever prize essay in a university competition. The mischief may be slight when we are merely considering literary effect. But it points to a graver evil. In political discussions, the half-trained mind has strong convictions about some particular case, and then finds it easiest to justify its conviction by some sweeping general principle. It really starts, speaking in terms of logic, by assuming the truth of its minor and takes for granted that any major which will cover the minor is therefore established. Nothing saves so much trouble in thinking as the acceptance of a good sounding generality or a self-evident truth. Where your poor scientific worker plods along, testing the truth of his argument at every point, making qualifications and reservations, and admitting that every general principle may require to be modified in concrete cases, you can thus both jump to your conclusion and assume the airs of a philosopher. It is, I fancy, for this reason that people have such a tendency to lay down absolute rules about really difficult points. It is so much easier to say at once that all drinking ought to be suppressed, than to consider how, in actual circumstances, sobriety can be judiciously encouraged; and by assuming a good self-evident law and denouncing your opponents as immoral worshippers of expediency, you place yourself in an enviable position of moral dignity and inaccessibility. No argument can touch you. These abstract rules, too, have the convenience of being strangely ambiguous. I have been almost pathetically affected when I have observed how some thoroughly commonplace person plumes himself on preserving his consistency because he sticks resolutely to his party dogmas, even when their whole meaning has evaporated. Some English radicals boasted of consistency because they refused to be convinced by experience that republicans under a
