from the superstition of the Aristotelians, and exalting it to something higher than a mere verbal exercise for school-boys. The attack that Locke opened with such tremendous effect on the _a priori_ school of philosophy was never more ably supported than by the "Logic" and controversial writings of Mr. Mill. The remarkable fact in regard to both these great thinkers--these conquerors in the realms of abstract speculation--is their relation to politics. Locke was the political philosopher of the Revolution of 1688; Mr. Mill has been the political philosopher of the democracy of the nineteenth century. The vast space that lies between their treatises represents a difference, not in the men, but in the times. Locke found opposed to the common weal an odious theory of arbitrary and absolute power. It is interesting to remember what were the giants necessary to be slain in those days. The titles of his first chapters on "Government" significantly attest the rudimentary condition of political philosophy in Locke's day. Adam was generally considered to have had a divine power of government, which was transmitted to a favored few of his descendants. Accordingly Locke disposes of Adam's title to sovereignty to whatever origin it may have been ascribed,--to "creation," "donation," "the subjection of Eve," or "fatherhood." There is something almost ludicrous in discussing fundamental questions of government with reference to such scriptural topics; and it is a striking evidence of the change that has passed over England since the Revolution, that, whereas Locke's argument looks like a commentary on the Bible, even the bishops now do not in Parliament quote the Bible on the question of marriage with a deceased wife's sister. Nevertheless Locke clearly propounded the great principle, which, in spite of many errors and much selfishness, has been the fruitful heritage of the Whig party. "Political power, then, I take to be a right of making laws with penalties of death, and consequently all less penalties, for the regulating and preserving of property, and of employing the force of the community in the execution of such laws, and in the defence of the commonwealth from foreign injury, _and all this only for the public good_." Locke also enounced the maxim, that the state of nature is one of equality. Mr. Mill's special views on the land question are not without parallel in Locke; for that acute thinker distinctively laid down that "labor" was the true ground even of property in land. Still it must be confessed that Locke's political philosophy is much cruder than Mr. Mill's. His "Essay on Government" is as the rough work of a boy of genius, the "Representative Government" a finished work of art of the experienced master. And this difference corresponds with the rate of political progress. The English constitution, as we now understand it, was unknown at the Revolution: it had to be slowly created. Now the great task of the
