No principle ever was announced of more practical importance in legislating for mankind, than is contained in this passage. The doctrine is somewhat obscurely stated, and not with the precision which in general distinguishes the French writers; but the import of it seems to be this--That no system of government can long exist among men, unless it is substantially, and in the majority of cases, founded in reason and justice, and sanctioned by experienced utility for the people among whom it exists; and therefore, that we may predicate with perfect certainty of any institution which has been generally extended and long established, that it has been upon the whole beneficial, and should be modified or altered with a very cautious hand. That this proposition is true, will probably be disputed by none who have thought much and dispassionately on human affairs; for all human institutions are formed and supported by men, and unless men had some reason for supporting them, they would speedily sink to the ground. It is in vain to say a privileged class have got possession of the power, and they make use of it to perpetuate these abuses. Doubtless, they are always sufficiently inclined to do so; but a privileged class, or a despot, is always a mere handful against the great body of the people; and unless their power is supported by the force of general opinion, founded on experienced utility upon the whole, it could not maintain its ground a single week. And this explains a fact observed by an able and ingenious writer of the present day,[20] that if almost all the great convulsions recorded in history are attentively considered, it will be found, that after a brief period of strenuous, and often almost superhuman effort, on the part of the people, they have terminated in the establishment of a government and institutions differing scarcely, except in name, from that which had preceded the struggle. It is hardly necessary to remark how striking a confirmation the English revolution of 1688, and the French of 1830, afford of this truth.
