In order, however, that they may be so employed successfully and correctly it is essential that the terms should be correctly defined, and that their popular use should conform to correct definitions. No doubt it is generally believed that the terms are easily understood, and present no difficulty. Probably the popular notion is, that liberty means doing as one has a mind to, and that it is a metaphysical or sentimental good. A little observation shows that there is no such thing in this world as doing as one has a mind to. There is no man, from the tramp up to the President, the Pope, or the Czar, who can do as he has a mind to. There never has been any man, from the primitive barbarian up to a Humboldt or a Darwin, who could do as he had a mind to. The "Bohemian" who determines to realize some sort of liberty of this kind accomplishes his purpose only by sacrificing most of the rights and turning his back on most of the duties of a civilized man, while filching as much as he can of the advantages of living in a civilized state. Moreover, liberty is not a metaphysical or sentimental thing at all. It is positive, practical, and actual. It is produced and maintained by law and institutions, and is, therefore, concrete and historical. Sometimes we speak distinctively of civil liberty; but if there be any liberty other than civil liberty--that is, liberty under law--it is a mere fiction of the schoolmen, which they may be left to discuss. Even as I write, however, I find in a leading review the following definition of liberty: Civil liberty is "the result of the restraint exercised by the sovereign people on the more powerful individuals and classes of the community, preventing them from availing themselves of the excess of their power to the detriment of the other classes." This definition lays the foundation for the result which it is apparently desired to reach, that "a government by the people can in no case become a paternal government, since its law-makers are its mandatories and servants carrying out its will, and not its fathers or its masters." Here we have the most mischievous fallacy under the general topic which I am discussing distinctly formulated. In the definition of liberty it will be noticed that liberty is construed as the act of the sovereign people against somebody who must, of course, be differentiated from the sovereign people. Whenever "people" is used in this sense for anything less than the total population, man, woman, child, and baby, and whenever the great dogmas which contain the word "people" are construed under the limited definition of "people," there is always fallacy.
