XXI. We believe there is sufficient soundness in Secular principles to make way in the world. All that is wanted is that advocates of them shall have clear notions of the value of method in their work. To the novice in advocacy policy seems a crime--at least, many so describe it. Unable himself to see his way, the tyro fights at everything and everybody equally; and too vain to own his failure, he declares that the right way. Not knowing that progress is an art, and an art requiring the union of many qualities, he denies all art, cries down policy, and erects blundering into a virtue. Compare the way which Havelock reached Lucknow, and the way in which Sir Colin Campbell performed the same feat, and you see the difference between courage without, and courage with strategy. It was because magnitudes existed, which were inaccessible and incapable of direct measurement, that mathematics arose. Finding direct measurement so often impossible, men were compelled to find means of ascertaining magnitude and distance indirectly. Hence mathematics became a scientific policy. Mathematics is but policy of measurement--grammar but the policy of speech--logic but the policy of reason--arithmetic but the policy of calculation--temperance but the policy of health--trigonometry but the policy of navigation--roads but the policy of transit--music but the policy of controlling sound--art but the policy of beauty--law but the policy of protection--discipline but the policy of strength--love but the policy of affection. An enemy may object to our having a policy, because it suits his purpose that we should be without one; but that a friend should object to our having a policy is one of those incredible infatuations which converts partisans into unconscious traitors. The policy adopted may be a bad policy, and no policy at all is idiotcy. If a policy be bad, criticise and amend it; but to denounce all policy is to commit your cause to the providence of Bedlam. If, therefore, throughout all intelligent control of Nature and humanity, policy is the one supreme mark of wisdom, why should it be dishonourable to study the policy of opinion? He who consistently objects to policy, would build railway engines without safety valves, and dismiss them from stations without drivers; he would abolish turnpike roads and streets, and leave us to find our way at random; he would recommend that vessels be made without helms, and sail without captains, that armies fight without discipline, and artillery-men should fire before loading, and when pointing their guns, should aim at nothing. In fine, a man without policy, honestly and intelligently opposed to policy, would build his house with the roof downwards, and plant his trees with their roots in the air; he would kick his friend and hug his enemy; he would pay wages to servants who would not work, govern without rule, speak without thought, think without reason, act without purpose, be a knave by accident, and a fool by design.
