Hence, it follows, that if a thing is to be useful, it must be not only of an availing nature, but in availing hands. Or, in accurate terms, usefulness is value in the hands of the valiant; so that this science of wealth being, as we have just seen, when regarded as the science of Accumulation, accumulative of capacity as well as of material,--when regarded as the science of Distribution, is distribution not absolute, but discriminate; not of every thing to every man, but of the right thing to the right man. A difficult science, dependent on more than arithmetic. Wealth, therefore, is "THE POSSESSION OF THE VALUABLE BY THE VALIANT;" and in considering it as a power existing in a nation, the two elements, the value of the thing, and the valour of its possessor, must be estimated together. Whence it appears that many of the persons commonly considered wealthy, are in reality no more wealthy than the locks of their own strong boxes are; they being inherently and eternally incapable of wealth; and operating for the nation, in an economical point of view, either as pools of dead water, and eddies in a stream (which, so long as the stream flows, are useless, or serve only to drown people, but may become of importance in a state of stagnation, should the stream dry); or else, as dams in a river, of which the ultimate service depends not on the dam, but the miller; or else, as mere accidental stays and impediments, acting, not as wealth, but (for we ought to have a correspondent term) as "illth," causing various devastation and trouble around them in all directions; or lastly, act not at all, but are merely animated conditions of delay (no use being possible of anything they have until they are dead), in which last condition they are nevertheless often useful _as_ delays, and "impedimenta," if a nation is apt to move too fast. This being so, the difficulty of the true science of Political Economy lies not merely in the need of developing manly character to deal with material value, but in the fact, that while the manly character and material value only form wealth by their conjunction, they have nevertheless a mutually destructive operation on each other. For the manly character is apt to ignore, or even cast away, the material value:--whence that of Pope:-- "Sure, of qualities demanding praise More go to ruin fortunes, than to raise."
