Generally, indeed, it may be maintained that right is of a nature analogous to that of certain chemical substances, which cannot be exhibited in a pure and isolated condition, but at the most only with a small admixture of some other substance, which serves as a vehicle for them, or gives them the necessary consistency; such as fluorine, or even alcohol, or prussic acid. Pursuing the analogy we may say that right, if it is to gain a footing in the world and really prevail, must of necessity be supplemented by a small amount of arbitrary force, in order that, notwithstanding its merely ideal and therefore ethereal nature, it may be able to work and subsist in the real and material world, and not evaporate and vanish into the clouds, as it does in Hesoid. Birth-right of every description, all heritable privileges, every form of national religion, and so on, may be regarded as the necessary chemical base or alloy; inasmuch as it is only when right has some such firm and actual foundation that it can be enforced and consistently vindicated. They form for right a sort of [Greek: os moi pou sto]--a fulcrum for supporting its lever. Linnaeus adopted a vegetable system of an artificial and arbitrary character. It cannot be replaced by a natural one, no matter how reasonable the change might be, or how often it has been attempted to make it, because no other system could ever yield the same certainty and stability of definition. Just in the same way the artificial and arbitrary basis on which, as has been shown, the constitution of a State rests, can never be replaced by a purely natural basis. A natural basis would aim at doing away with the conditions that have been mentioned: in the place of the privileges of birth it would put those of personal merit; in the place of the national religion, the results of rationalistic inquiry, and so on. However agreeable to reason this might all prove, the change could not be made; because a natural basis would lack that certainty and fixity of definition which alone secures the stability of the commonwealth. A constitution which embodied abstract right alone would be an excellent thing for natures other than human, but since the great majority of men are extremely egoistic, unjust, inconsiderate, deceitful, and sometimes even malicious; since in addition they are endowed with very scanty intelligence there arises the necessity for a power that shall be concentrated in one man, a power that shall be above all law and right, and be completely irresponsible, nay, to which everything shall yield as to something that is regarded as a creature of a higher kind, a ruler by the grace of God. It is only thus that men can be permanently held in check and governed.
