noblest type of man, and aim simply at maintaining the largest possible number of persons of that class, and it will be found that the largest possible number of every healthy subordinate class must necessarily be produced also. The perfect type of manhood, as just stated, involves the perfections (whatever we may hereafter determine these to be) of his body, affections, and intelligence. The material things, therefore, which it is the object of political economy to produce and use (or accumulate for use), are things which serve either to sustain and comfort the body, or exercise rightly the affections and form the intelligence.[67] Whatever truly serves either of these purposes is "useful" to man, wholesome, healthful, helpful, or holy. By seeking such things, man prolongs and increases his life upon the earth. [67] It may be observed, in anticipation of some of our future results, that while some conditions of the affections are aimed at by the economist as final, others are necessary to him as his own instruments: as he obtains them in greater or less degree his own farther work becomes more or less possible. Such, for instance, are the fortifying virtues, which the wisest men of all time have, with more or less distinctness, arranged under the general heads of Prudence, or Discretion (the spirit which discerns and adopts rightly); Justice (the spirit which rules and divides rightly); Fortitude (the spirit which persists and endures rightly); and Temperance (the spirit which stops and refuses rightly); or in shorter terms still, the virtues which teach how to consist, assist, persist, and desist. These outermost virtues are not only the means of protecting and prolonging life itself, but they are the chief guards or sources of the material means of life, and are the visible governing powers and princes of economy. Thus (reserving detailed statements for the sequel) precisely according to the number of just men in a nation, is their power of avoiding either intestine or foreign war. All disputes may be peaceably settled, if a sufficient number of persons have been trained to submit to the principles of justice. The necessity for war is in direct ratio to the number of unjust persons who are incapable of determining a quarrel but by violence. Whether the injustice take the form of the desire of dominion, or of refusal to submit to it, or of lust of territory, or lust of money, or of mere irregular passion and wanton will, the result is economically the same;--loss of the quantity of power and life consumed in repressing the injustice, as well as of that requiring to be repressed, added to the material and moral destruction caused by the fact of war.
