This question therefore needs careful consideration, and a satisfactory answer can only be derived from an examination of the essential duty of the State.

If this duty consists in giving scope to the highest intellectual and moral development of the citizens, and in co-operating in the moral education of the human race, then the State's own acts must necessarily conform to the moral laws. But the acts of the State cannot be judged by the standard of individual morality. If the State wished to conform to this standard it would often find itself at variance with its own particular duties. The morality of the State must be developed out of its own peculiar essence, just as individual morality is rooted in the personality of the man and his duties towards society. The morality of the State must be judged by the nature and raison d'être of the State, and not of the individual citizen. But the end-all and be-all of a State is power, and "he who is not man enough to look this truth in the face should not meddle in politics." [F]

[Footnote F: Treitschke, "Politik," i., p 3, and ii., p 28.]

Machiavelli was the first to declare that the keynote of every policy was the advancement of power. This term, however, has acquired, since the German Reformation, a meaning other than that of the shrewd Florentine. To him power was desirable in itself; for us "the State is not physical power as an end in itself, it is power to protect and promote the higher interests"; "power must justify itself by being applied for the greatest good of mankind." [G]

[Footnote G: Treitschke, "Politik," i., p 3, and ii., p 28.]

The criterion of the personal morality of the individual "rests in the last resort on the question whether he has recognized and developed his own nature to the highest attainable degree of perfection." [H] If the same standard is applied to the State, then "its highest moral duty is to increase its power. The individual must sacrifice himself for the higher community of which he is a member; but the State is itself the highest conception in the wider community of man, and therefore the duty of self-annihilation does not enter into the case. The Christian duty of sacrifice for something higher does not exist for the State, for there is nothing higher than it in the world's history; consequently it cannot sacrifice itself to something higher. When a State sees its downfall staring it in the face, we applaud if it succumbs sword in hand. A sacrifice made to an alien nation not only is immoral, but contradicts the idea of self-preservation, which is the highest ideal of a State." [I]

[Footnote I: Ibid., i., p 3.]

I have thought it impossible to explain the foundations of political morality better than in the words of our great national historian. But we can reach the same conclusions by another road. The individual is responsible only for himself. If, either from weakness or from moral reasons, he neglects his own advantage, he only injures himself, the consequences of his actions recoil only on him. The situation is quite different in the case of a State. It represents the ramifying and often conflicting interests of a community. Should it from any reason neglect the interests, it not only to some extent prejudices itself as a legal personality, but it injures also the body of private interests which it represents. This incalculably far-reaching detriment affects not merely one individual responsible merely to himself, but a mass of individuals and the community. Accordingly it is a moral duty of the State to remain loyal to its own peculiar function as guardian and promoter of all higher interests. This duty it cannot fulfil unless it possesses the needful power.

The increase of this power is thus from this standpoint also the first and foremost duty of the State. This aspect of the question supplies a fair standard by which the morality of the actions of the State can be estimated. The crucial question is, How far has the State performed this duty, and thus served the interests of the community? And this not merely in the material sense, but in the higher meaning that material interests are justifiable only so far as they promote the power of the State, and thus indirectly its higher aims.
